Abstract

This study aims to delineate the breadth and depth of the geothermal reservoir and the resulting temperature. The method used is a compilation of lithology, alteration and the temperature profile that is supported by literature references and well data. Delinasi prospect area and deep reservoir of data viewed by lithology, alteration and the temperature profile. Regional prospects in the region of 2000C or more temperatures are also characterized by the presence of epidote minerals and are on lava and pyroclastic stratigraphy perselingan. The results obtained two different reservoir sites, the first located at depths of 800-1300 m above sea level and an area reached 1.37 x 107 m2., While the second is located at a depth (900 m - bottom) and an area of more than 3, 38 x 106 m2. Based on the temperature profile, the type of prospect geothermal reservoir in this area is the type of dominance of steam. .

Abstract

The morphology of investigated area is a flat area and hilly area at elevation reaching 20 meters above the sea level. The lateritic nickel is a residual soil from weathering, resulting from serpentinite, hasburgite and dunite being ultramafic complex according to the geologic map of Batui sheets, Celebes.The extent of investigation is 8000 hectare as the permit from the regency of Banggai, and the thichness of nickel bearing lateritic soil averaging 2 meters, and therefore is roughly estimated 160.000.000 cubic meters. If the specivic gravity of lateritic soil is 2.6 and nickel content average 0.8 %, the reserve of lateritic nickel is will be 160,000,000 M³x 2.6 x 0.8% = 3,328,000 Tons. It is suggested to be mined by open pit method because the lateritic soil on the surface with only averaging thichness of soil 2 meters.

Abstract

Studies of the Quaternary depositional cycles based on character of sea-level changes in the Krueng Aceh Valley ( Aceh Besar), revealed seven of depositional fasies. These depositional fasies consist of beach/ beach ridges (Fep/ Fepp), nearshore (Feldp), offshore (Fellp), river channel (Feas), floodplain (Fedb), swamp (Fer), and marsh (Ferb) deposits. Based on correlation of the lateral and vertical variation of the Quaternary deposits, four Interval of depositional facies (IFP A-D) occurred. Each of depositional facies is, characterized by variation of the depositional environment alternating which is controlled by sea-level changes under influenced by climate circulation and tectonic. Probably, the character of each depositional interval could be called as cycle of five ordo of sea level changes which correlated with Milankovitch cycle of 20,000 years.The study was based on analyses of sedimentology and stratigraphy of nine borehole informations, and the penetration of the bore head varied from 51,50 to 125 m. Three stratigraphical cross section have been correlated, that is BD2 – BD8, BD2 – BD5, and BD8 – BD5 cross sections.

Abstract

Upstream watershed Cikapundung or known by the name of Lembang Basin, including the Regency Bandung, West Java. In general, the rock consists of five units (Plistosen Down - Holocene), the Breccia Unit Volcano (Formation Cikapundung), Old Volcano Deposition Unit, tuff unit (Formation Cibeureum), Sandy Tuff Unit (Cikidang Formation) and colluvium. Lembang normal faults trending east-west which is a major fault structure which limits the rate of soil water retention from the Upper Basin watershed Cikapundung Bandung below it. Land classification is characterized by a mixture of rural land in the area of agriculture and plantation, until the presence of centers planned settlements (real estate). Broad watershed is 80.475 km2, around 51.575 kms and the degree of roundness (Rc) = 0.380. Tributaries of the river hierarchy order 1 = 449 types, the order of 2 = 89, the order of 3 = 23, order 4 = 7, the order of 5 = 3 and order 6 = 1 types. Different numbers of streams with stream order 1 and order 2 is very large, causing Rb values of order 1 to 2 becomes large is 5.04. In addition there is a small Rb between orders 4 and 5 is 2.33. Thus, the influence of valley pond clear fault control morphometry study area. Elevation upstream and downstream (estuary) river is generally inversely proportional to the level-order tributaries. Elevation difference between upstream and downstream of all the rivers are relatively the same order. Basin wide average is consistently proportional to the level of orders the river, while the. tributaries frequency (F) is inversely proportional. Kc and the Rc value is below 1, this

Abstract

The outcrop findings of the inverted Basin fill in the Ombilin Basin Central Sumatra, provides a new opportunity for research into provenance and sediment dispersal system. Sandstone samples were taken for petrographic examination from the Eocene Brani Formation, the Oligocene Sawahlunto Formation and the Miocene Ombilin Formation.Major diagenetic features such as compaction, cementation, replacement and grain deformation are commonly present in all samples, but however they exhibit a different intensity level and variation in detail to each formation.Metamorphic rock fragment, marble rock fragment and plagioclase grain are the distinctive grain types (petrographic classes) of the Brani Formation sandstone. Petrographic classes that characterize the overall populated sandstone of the Sawahlunto Formation consist of undulosed monocrystalline quartz and lithic chert. Petrographic classes that characterize the overall populated sandstone of the Ombilin Formation comprises sedimentary rock fragment (authigenic grain and intrabasinal clast) and lithic volcanic. In terms of parental rock assemblage, it is identified that the provenance (parental rock) of the sand grain in the three formations are possibly sourced from five rock assemblages: A). Pre Tertiary Extrabasinal sediment and volcanic; B). Pre Tertiary Extrabasinal Metamorphic; C). Extrabasinal contemporaneous volcanism; D). Intrabasinal contemporaneous sediment; E). Pre Tertiary Extrabasinal granitoid pluton.
