Abstract

Magnetic anomaly in the Malingping - Bayah and surrounding areas, ranging from -650 nT to +270 nT, can be divided into three groups. The first group is the low anomaly with a value range from -650 nT to -250 nT, the second group is middle anomaly with a value range from -250 nT to + 50 nT, and the third group is high anomaly with a value range from + 50 nT to +270 nT. Low anomaly zone is thought to be the effect of intrution of acid rocks which is located in 500 to 2000 m depth. This is supported by the existing of granodiorite intrusion of Cihara (Tomg) that also coincides with low anomaly zone. The granodiorite intrusion is thougt to have played an important role in sulfide, gold (Au), and silver (Ag) mineralization which is found in the Cikotok and Cirotan areas. Keywords : Geomagnetic anomalies, Malingping, granodiorite of Cihara

Abstract

The Pendul Intrusion consists of andesite, diabas, diorite, and gabbro; that are widely distributed within the Jiwo Hills, south of Klaten, Central Jawa. K/Ar datings of 4 rock indicate that there are two magmatism episodes; Middle Eocene - Early Oligocene (39,82 - 30,04 Ma) and Middle Miocene (17,22 - 13,85 Ma). Trace element concentrations of the Pendul rocks characterize that the magma was originated from subduction environment as a result of mantle wedge melting. The rocks are characterized by low Nb relative to K and La contents. The rare earth element signatures indicate that the Pendul magmas might have come from defferent parent magmas. The Middle Eocene - Early Oligocene parent magmas posses lower rare earth element concentrations than those of the Middle Miocene ones. Keywords: Bayat, Pendul Intrusion, two magmatism episodes, stratigraphy

Abstract

The Early Miocene Pakaurangi Formation, Waitakere Group, have a high diversity of Ostracoda. Key species include Loxoconcha propunctata, Bradleya semiarata, Bradleya lactea pakaurangia, Hemycythere tarakohensis and Bairdia canterburyensis, and indicate an Altonian age, completely in agreement with foraminiferal ages from this area by other workers.The species Trachyleberis zeacristata Hornibrook is transferred to Henryhowella. Paijenborchella iocosa Kingma, and many generic level taxa were also found in a borehole in Bojonegoro, East Jawa, Indonesia. The previously recorded Clifdenian to Waitotaran range of Henryhowella probesioides Hornibrook is extended downwards into the Altonian. The Ostracoda also show the paleoenvironment of the Pakaurangi Formation to be littoral to neritic, which is also in agreement with the evidence of foraminifera and molluscs as reported by previous workers. Keywords: Ostracoda, Pakaurangi Formation, Waitakere Group, Altonian, New Zealand

Abstract

Geomagnetic and gravity analyses were carried out in the Banjarmasin quadrangle, South Kalimantan. Qualitative analysis of gravity anomaly show that ophiolite is located in the central quadrangle with anomaly values between 550 µms-2 and 750 µms-2 trending southwest-northeast.Geomagnetic qualitative analysis presents high  geomagnetic anomaly part values between 0 nT and 450 nT in the southern area, while low anomaly between -750 nT to 0 nT, generally in northern part of the sheet. Quantitative analysis was done by making subsurface geological profiles model AB, CD, and EF. Ophiolite rock from the gravity modeling have density between 2.7 gr/cc and 2.9 gr/cc. This is probably caused by fragmentation process which affect the basement oceanic rock mix by Pre-Cretaceous rock such as chert, metamorphic and carbonat rocks, accordingly this reduce the rock density, while geomagnetic model have susceptibility of 0.15 SI. Ophiolite rock was interpreted as oceanic crust bolder that overlay on the granitic crust which has less magnetization. This shows a subduction model which cause oceanic crust uplifted and laid on the upper of granitic crust and than revealed as Bobaris and Manjam ophiolite belts. Keywords : Geomagnetic, gravity, ophiolite, oceanic crust

Abstract

Oil shale, as one of alternative energy resources, is recognized in the Late Eosen - Oligocene Kasiro Formation, located in the Rawas Ulu and Batang Asai areas. Based on SEM analysis, the shale  consists of smektite-illite, illite,  kaolinite, organic matter as liptinite (sporinite,and alginite) and contains oil droplet.The oil shale is composed of smectite-illite and illite characterised by wavy parallel fissile,while kaolinite clays show irregular shape characters. The shale has undergone a diagenetic process within an early mesodiagenetic level. Organic matter maturity level of the oil shale, in general, is the immature up to early mature. Keywords : oil shale,clay minerals,smectite-illite,  organic matter

Abstract

Andesitic lavas and rhyolitic tuffs are the main products of the Maninjau Lake during Pleistocene. The lava is distributed up to radius of 20 km, whiles the tuff 100 km that suggests a high explosive volcanic. The lava is exposed beautifully along the road from Bukit Tinggi to Lubuk Basung mapped as Qamj on the 1:250 000 geologic map of Padang Quadrangle. The lava is having sheeting joint in some parts, dark gray, highly porphyritic in texture with phenocrysts of plagioclase, clino- pyroxene, ortho-pyroxene and opaques. Quartz phenocryst occurs in rhyolite lavas that are rarely found in the area. Xenoliths of diorite are occurred in some andesite. The lavas have narrow range in silica composition ranging from 54-60 wt % and rarely up to 69 wt%. K2O versus SiO2 relationship shows that analyzed samples belong to calc-alkaline series which are mainly of high-K. While the trace element of the rocks is summarized on the spider diagram, here their patterns strongly resemble the typical of arc lavas with enrichment in large ion lithophile elements (LILE) and light rare earth elements (LREE) relative to high field strength elements (HFSE) and heavy REE (HREE). More over, these patterns show an Nb resembling the arc type magma commonly resulted from subduction, whether in island arc or active continental margin. The geochemical characteristic of the lava from Maninjau Lake is a lower concentration of Ba, Sr and La than other active continental margin like the Andes volcanic rocks. Like many other subducted related rocks, the andesite characterize a very evolved magma, where they have low MgO concentrations (3 wt%) with Mg# 30-53. According to the plate tectonic model, Sumatera is on the continental side to subduction process since Eocene until the present. The presence of subducted magma character in Maninjau Lake area was argued to have been accounted during the eastward subduction of the India-Australia Oceanic Crust. It seems also that Sumatra Fault Zone is a very important agent to conduit magma onto the surface in the Barisan Ranges including the lava resulted from Maninjau Lake. Keywords :  petrology, andesitic lava, rhyolitic tuff, Maninjau, Pleistocene

Abstract

The parent rock of zeolite at the Sangkaropi-Mendila area is composed of altered lithic and glassy tuffs, which is included within Lamasi Volcanic of Oligocene age. The zeolit was originated from volcanic ash with involvement of hydrothermal process. It is indicated by the presence of hydrothermally altered minerals such as chlorite, epidote, clay mineral, carbonate and silica. Nineteen rock samples have been analysed for petrography, SEM, CEC, ASD, XRD, XRF and AAS. Petrographic and SEM analyses show that the types of zeolites are mordenite and heulandite. The mordenite is characterized by textures of rat's nest and fibres, while the heulandite has a blocky monoclinic crystal texture with CEC up to  108,43 meq/100 g. Only three samples of ASD and one sample of XRD treatment contain composition of mordenite. Results of the XRF analysis show contents of SiO2  (62,69%-81,03%), Al2O3  (9,90%-19,82%), CaO (0,10%-0,22%), Na2O (0,12%-4,32%), K2O (0,63%-6,88%) and LOI (1,26%-12,62%). A total resource of 168.480.000 tons of Sangkaropi-Mendila zeolite  was identified within an area of 360.000 m², offering a good prospect to the sectors of fishery, agriculture, waste handling and other industry. Keywords : zeolite, mordenite, heulandite, Sangkaropi, Mendila

Abstract

Marine geological survey of Ekspedisi Widya Nusantara (EWIN) LIPI 2016 was conducted by using RV Baruna Jaya VIII in the Sumba Waters from 4 to 26 August 2016. One of the aim of this survey is to understand the sea floor surface sediment characteristics and its influence to the benthic foraminifera distribution. Seven sediment samples were collected from sea floor surface in Sumba Strait, at the different location and depth using grabbing method with box corer. The samples have analyzed for the foraminifera content, sediment grain size, organic matter and carbonate content, and chemical element by XRF method. The living benthic foraminifera distribution increase to the east of the research area, which have higher content of the organic material and Fe, Rb, Zr, Zn and Sr elements in the sediment. The benthic foraminifera distribution most abundance founded at the depth of 800-1000 m with sediment types are sandy coarse silt  to sandy very coarse silt.Keywords: Benthic foraminifera, distribution, sea floor sediment, Sumba Strait. DOI: 10.33332/jgsm.2019.v20.1.17-26
