Since the source of arsenic is believed to be natural as widely reported in other deltaic aquifers of same age (Holocene), it is imperative to evaluate the soil characteristics for identifying the sources of arsenic and its mobilization mechanism. For this purpose, 49 soil samples were collected from near aquifer sites in all three talukas of Tando Muhammad Khan district. Visual analysis revealed that soil is light grey in color with fine texture ranging from silt to silty-clay. The X-ray diffraction study reveals the occurrence of quartz, mica and clay minerals in all collected soil samples. Plagioclase feldspar is second dominant mineral group in the order of albite (calcian) &gt;albite&gt;albite (disordered) = anorthite &gt; anorthite (sodian) = anorthite (disordered). Calcite is major carbonate mineral which is detected in 40 out of total 49 soil samples. The occurrence of other occasional minerals includes amesite, nitro-calcite, rutile and zinnwaldite. The frequency of micaceous minerals in collected samples is in the order of clinochlore&gt; polylithionite&gt; Biotite &gt; phlogopite&gt; muscovite. Polylithionite is found in about half of the total soil samples, where most of the aquifers contain arsenic &gt;20 μg/L (Khan, 2014). Phlogopite is observed in seven soil samples which are also associated with clinochlore. On the other hand, biotite is found in 14 sediment samples collected from Tando Muhammad Khan and Bhulri Shah Karim talukas and muscovite occurs in three soil samples of Tando Muhammad Khan taluka. It can be concluded from present study that fine-grained Phyllosilicates have strong affinity for arsenic retention. These sediments are important source of arsenic Indus delta and other deltaic plains of the world.</p> 2019-12-30T00:00:00+00:00 Copyright (c) 2019 Journal of Geoscience, Engineering, Environment, and Technology https://journal.uir.ac.id/index.php/JGEET/article/view/4258 The Weak Soil Investigation at the Slope Zone in the Hot Spring Area, Rokan Hulu, Indonesia 2020-02-23T00:56:01+00:00 Nur Islami islami@gmail.com <p>The slope failure can occur due to the soil on the slope area is relatively porous and the surface water is easily to move in the soil. The zone of the weak zone of the soil should be detected early to avoid the ground mass movement on the slope area. This study is to investigate the weak zone of the soil on the slope area of the hot spring tourism location using geoelectrical resistivity and soil property analysis methods. The Wenner configuration with a total of 40 electrodes has been employed at each four resistivity survey lines. The electrode spacing was adjusted to be 2 – 5 meter in order to get relatively higher resolution of the resistivity data. Soil samples were collected at several site to measure the soil characteristics of the study area. The soil analysis results show that the study area consist of gravel, sand, clay, silt and weathered methasediment. The geoelectrical resistivity model shows the relatively low resistivity value of about 30 ohm.m at the slope zone which is indicating that the soil has higher porosity. Generally only a few locations with the weak soil zone detected in the slope of the hot spring area, however, it is not potential for the ground mass movement due to the soil is relatively thin. &nbsp;&nbsp;</p> 2019-12-30T00:00:00+00:00 Copyright (c) 2019 Journal of Geoscience, Engineering, Environment, and Technology https://journal.uir.ac.id/index.php/JGEET/article/view/2807 Evaluation of the Hydrocarbon Potentials of Shale Exposures at Okpekpe in Edo North 2020-02-22T23:08:16+00:00 Alexander Ogbamikhumi alexander.ogbamikhumi@uniben.edu Nosa Igbinigie nosa.igbinigie@uniben.edu Ovie Odokuma-Alonge ovie.odokuma-alonge@uniben.edu <p>This study evaluates the source rock characteristics of rock exposures along a newly exposed road cut in Okpekpe. An integrated technique of organic geochemical analysis and biostratigraphy evaluation were adopted to determine the source rock quality, Maturation index, kerogen types, depositional environment andsediment age.</p> <p>Results of organic geochemistry gave total organic carbon (TOC) value between 0.81 to 3.04 w.t% (2.08wt.% average) indicative of a good source potentials. The plot of Total Sulphur Content (TSC) against TOC suggests a transitional depositional environment for the samples while the plot of hydrogen index (HI) against oxygen index (OI) shows that the samples are capable of generating mixed type II/III kerogen.</p> <p>Palynological analysis revealed that the basal section of the exposure is characterized by the occurrences of typical and moderately rich Late Cretaceous – Early Tertiary palynomorphs. While the upper section is poorly rich&nbsp; in palynomorph abundance but with spot occurrences. The palynomophs asssemlages is of Late Maastrichtian - Early Paleocene and the outcrop is characterized by the presence of terrestrial pollens and spores indicating a continental to transitional depositional environment, typical of the Mamu Formation of the Anambra Basin.</p> 2019-12-30T00:00:00+00:00 Copyright (c) 2019 Journal of Geoscience, Engineering, Environment, and Technology https://journal.uir.ac.id/index.php/JGEET/article/view/2590 An Integrated Approach in Geophysical Investigation of Road Failure in Crystalline Basement Area of Nigeria 2020-02-22T23:08:18+00:00 Olabanji Adeolu Ojo adeolu.ojo50@gmail.com Victor Adejumo victoradejumo7@gmail.com obaromi Olubunmi obaromi@gmail.com <p>The result of the geophysical investigation carried out to access the cause of road failure and remediation measures along Ilesha-Osogbo expressway, Osun State, South-western Nigeria is presented. The study involved integrating the dipole-dipole technique of electrical resistivity method with the ground penetrating radar (GPR) method. Two dipole-dipole traverses, one long and 20 short GPR profiles were established across the failed section of the road. The dipole-dipole data were interpreted using the Diprowin software to produce the pseudo-section while the GPR data were interpreted using the RadProwin to produce the radargram. The result revealed that the failed road exhibit incompetent layer of resistivity values ranging between 17 Ωm to 171 Ωm lying between two competent layers of resistivity values greater than 200 Ωm. A combination of the dipole-dipole technique and the GPR techniques revealed the depth extend to failure to about 4.5 meters to 5 meters deep which overlie a basement rock of undifferentiated gneiss, a rock that is easily prone to weathering. The water level was observed to occur at shallow depth of about 2 meters and infiltrates the entire weathered layer. The shallow groundwater level coupled with the water-logged clayey layer derived from the weathered materials from basement rock were found responsible for the failure of this section of the road. The study recommends the excavation of the waterlogged clayey layer to a depth of about 5 to 6 meters deep into the subsurface and replacement first with heavy boulders of granitic materials and later overlaid with a thick layer of highly resistive landfill materials such as laterite. The result of the two techniques used in this work have proved to be supportive due to the integration of the double dipole technique with the GPR technique, a relatively new technique recently being introduced into road failure mapping.</p> 2019-12-30T00:00:00+00:00 Copyright (c) 2019 Journal of Geoscience, Engineering, Environment, and Technology https://journal.uir.ac.id/index.php/JGEET/article/view/3783 Geotourism on XIII Koto Kampar: an Approach for Sustainable Eco-Geo System 2020-02-22T23:08:21+00:00 Adi Suryadi adi.suryadi@eng.uir.ac.id Tiggi Choanji tiggich@eng.uir.ac.id Yuniarti Yuskar yuniarti_yuskar@eng.uir.ac.id Nanda Natasia nanda@gmail.com Tristan Aulia Akhsan tristan@gmail.com M Revanda Syahputra Revanda@gmail.com <p>XIII Koto Kampar has become one of the potential geotourism destinations in Riau Province.

This volcano has side eruption centers or on the slopes of the volcano. The morphology of parasitic eruptions in this volcanoes complex includes maars and boccas. There are about 64 parasitic eruption centers consisting of 37 volcanic cones (bocca) and 27 ranu (maar).</p> <p>The purpose of this research is to study the characteristics of lithology and petrogenesis of this volcano complex, especially in Ranu Pakis and surrounding areas. The analytical method used is to do geological mapping and petrographic analysis.</p> <p>The lithology found in this research area consists of magmatic and phreatomagmatic eruption deposits. Genetically this lithology includes pyroclastic flow, pyroclastic fall (scoria fall and phreatomagmatic scoria fall/accretionary lapili), tuff (phreatic) and basaltic lava. In some pyroclastic deposits, especially in maar there are fragments of accretionary lapilli, while in bocca there are basaltic lavas. Other fragments present in pyroclastic deposits are basalt scoria blocks and bombs embedded in the groundmass of volcanic ash. The results of petrographic analysis indicate that the volcanic rocks in the study area are calc alkaline affinity consisting of pyroxene andesite, basalt and pyroxene basalt lava. The pyroxene basalt lava is composed by plagioclase, clinopyroxene and little olivine embedded in the volcanic glass. Lavas are structured scoria and textured porphyritic, intersertal, trachytic, aphyric and pilotaxitic. Trachytic texture is found in the basalt fragments of pyroxene from the pyroclastic fall deposits in Ranu Pakis and Ranu Wurung. While pyroxene andesite lavas composed by plagioclase, clinopyroxene embedded in the volcanic glass. Lavas are structured scoria and textured porphyritic, intergranular, pilotaxitic and aphyric.</p> 2019-12-30T00:00:00+00:00 Copyright (c) 2019 Journal of Geoscience, Engineering, Environment, and Technology https://journal.uir.ac.id/index.php/JGEET/article/view/3903 Rock Formation Acid Mine Drainage in Epithermal Gold Mineralization, Pandeglang, Banten Province 2020-02-22T23:08:26+00:00 Dudi Nasrudin Usman dudi.n.usman@gmail.com Sri Widayati widayati_teknik@yahoo.com Sriyanti Sriyanti sriyanti.tambang@yahoo.com Era Setiawan Era@gmail.com <p>Mine acid water is acidic water and contains iron and sulfate, which is formed under natural conditions when geological strata containing pyrites are exposed to an oxidizing atmosphere or environment. One of the impacts of the mineralization zone where there is a mining process is the potential for the formation of acid mine drainage, especially in the Cibaliung gold mineralization area and its surroundings, Pandeglang Regency, Banten Province. Acid-forming sulfide minerals include pyrite (FeS2), headquarters (FeS2), picoliters (FexSx), calcocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), chalocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), chalocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), galena (PbS) ) and sphalerite (ZnS). Of all these minerals, pyrite is the most dominant sulfide in acid formation.</p> <p>Alkaline mine water (alkaline mine drainage) is mine water that has an acidity level (pH) of 6 or more, containing alkalinity but still containing dissolved metals that can produce acids. The quality of mine water, acid or alkali, depends on the presence or absence of acid mineral content (sulfides) and alkaline materials in the geological strata.</p> <p>Acid water formation tends to be more intensive in mining areas. This can be prevented by avoiding exposure to sulfide-containing materials in the free air. Acid-forming sulfide minerals include pyrite (FeS2), headquarters (FeS2), picoliters (FexSx), calcocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), chalocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), chalocytes (CuS), covellite (CuS), chalcopyrite (CuFeS2), molybdenite (MoS), mulenite (NiS), galena (PbS) ) and sphalerite (ZnS). Of all these minerals, pyrite is the most dominant sulfide in acid formation. Formation of potential acidic water also occurs in tailings which are residues/processing residues containing sulfide minerals. The formation of acid mine drainage does not always develop in every sulfide-ore mining. In certain types of ore deposits, there are neutralizing agents which prevent the formation of acid mine drainage.</p> 2019-12-30T00:00:00+00:00 Copyright (c) 2019 Journal of Geoscience, Engineering, Environment, and Technology https://journal.uir.ac.id/index.php/JGEET/article/view/3918 The Hydrochemistry of Groundwater in Jambakan, Klaten Regency, Central Java Province, Indonesia 2020-02-22T23:08:29+00:00 Ekha Yogafanny ekha.yogafanny@upnyk.ac.id Ardian Novianto ardian.novianto@upnyk.ac.id Rika Ernawati ernawati.rika@gmail.com Wibiana Wulan Nandari wibianawulan@gmail.com <p>Jambakan is a hamlet in Bayat District, Central Java Province, Indonesia, which commonly has brackish groundwater. Its unique geological profile leads to variation in groundwater quality that is even found between adjacent wells. This study was designed to identify the quality and hydrochemical type of groundwater and the distribution of brackish groundwater in Jambakan. It employed a quantitative method to analyzethe data collected in the field survey and groundwater quality data (major ions). Meanwhile, the hydrochemical facies of groundwater was interpreted from the plots of major ions on trilinear and quadrilateral Piper diagrams. The results showed that some of the groundwater quality parameters in six wells, namely A6, A34, A38, A65, A67, and A73, had exceeded the standard thresholds. The parameters in question were TDS, EC, salinity, sodium, calcium, chloride, sulfate, magnesium, and hardness. Compared with the six wells, A40 and A45 had better quality. The distribution of brackish groundwater could not be modeled horizontally because salinity highly depends on rock layers where the observed wells are located. Based on the trilinear Piper plots, the groundwater consisted of four hydrochemical facies, namely magnesium bicarbonate, a mixed type, calcium chloride, and sodium chloride. Meanwhile, the quadrilateral Piper diagrams showed the presence of Type I (bicarbonate water), Type II (semi-bicarbonate water), Type III (evaporite water), and Type IVb-IVc (sulfate water) in the groundwater of Jambakan Hamlet.</p> 2019-12-30T00:00:00+00:00 Copyright (c) 2019 Journal of Geoscience, Engineering, Environment, and Technology https://journal.uir.ac.id/index.php/JGEET/article/view/4101 Analysis of Land Cover Changing and Vegetation Index at Kuranji Watershed in Padang, West Sumatera, Indonesia 2020-02-22T23:08:31+00:00 Rifky Putera rifky.putera@gmail.com Junaidi Junaidi junaidi@eng.unand.ac.id Ahmad Junaidi ahmad_junaidi@eng.unand.ac.id <p>Various activities around Kuranji watershed included the land conversioncan be impacted to topographic condition and also contributed to altering the vegetation density. Remote sensing technology is an effective methodfor land cover mapping. The objectives of the present study were to analyze the changing of land cover and classifying the vegetation density index in the upstream Kuranji Watershed. This study was conducted at Kuranji Watershed in Padang, West Sumatera Province. Two Landsat images representing the changing of the watershed area during 2017 and 2018 as well as obtaining the classification of vegetation density during corresponding years.Landsat 8 OLI images were classified using a supervised classification technique, then computed the vegetation index using the Normalized Difference Vegetation Index (NDVI). The result showed that the extension of forest area, settlement area and paddy field (283.92; 35.06; and 27 Ha, respectively) and decline of mix dryland agriculture, shrub and garden area (93.68; 277.43; and 190.95 Ha respectively). Decreasing of dense vegetation found at lower dense class (6.47 Ha) and highest dense class (5535.35 Ha). Therefore, the increasing area found at the cloud, dense and higher dense class (93.17; 5525.1; and 109.94 Ha, respectively). So, it is highlighted that changing land cover and vegetation index happen during the only one-year period.</p> 2019-12-30T00:00:00+00:00 Copyright (c) 2019 Journal of Geoscience, Engineering, Environment, and Technology https://journal.uir.ac.id/index.php/JGEET/article/view/4672 Back matter JGEET Vol 04 No 04 2019 2020-02-22T23:08:14+00:00 JGEET (J.
