BSC Geology adalah jurnal yang dikelola oleh Fakultas Teknik Geologi Universitas Padjadjaran,terbit 3 kali dalam setahun (April, Agustus, dan Desember), yang menerbitkan karya tulis ilmiah dalam bidang kebumian terutama yang berkaitan dengan geologi seperti : Petrologi Paleontologi Geomorfologi Stratigrafi Geologi Dinamik Geologi Lingkungan dan Hidrogeologi Geologi Teknik Geokimia Geofisika Sedimentologi. Setiap artikel yang akan diterbitkan adalah bersifat tanpa biaya (no processing charges dan no submission charges). Dewan redaksi dan penerbit tidak pernah meminta bayaran untuk penerbitan pada jurnal ini. Tujuan dari jurnal ini adalah untuk memperkaya pengetahuan dan informasi tentang ilmu kebumian dan dapat dimanfaatkan untuk kemaslahatan bersama.

Abstract

Site plan of coal mining at Sorolangun, Jambi, is required geotechnical study for cut slope design. Mining plan. In open pit plan, to take stable slope, is required slope mass rating (SMR). SMR method is requiring rock mass rating value. According to soil and weak-rock mass properties of Muaraenim Formation, stable

Abstract

Geochemical studies of cap rock (overburden) on coal mining can be used as an indicator to predict the potential of acid mine drainage (AMD) not from coal itself. Coal overburden at PIT 1 IUP PWR, East Kalimantan composed by clay rocks. Geochemical measurements whic is carried from overburden samples KSD11 and KSD11H; shows that the overburden-based reference SNI 6597-2011 can be categorized as rock Type 1. Plotting on curve grouping PAF / NAF based on the relationship between pH and PAN PPAN KSD11dan KSD11H site shows all samples including NAF group. Analysis of TCLP (toxicity characteristic leaching procedure) showed that low dissolved ferrous metals (0.6 g / L) while the metal content of calcium and magnesium respectively are 0.23 g / L and 0.47 g / L (Table 4.7). When the calculated total of mole equivalents , calcium and magnesium is greater than the iron dissolved, so that although the acid formed will be neutralized. Thus overburden in Likasi PIT 1 is a type of cap rock that not form acid mine drainage when exposed in water and air, so it does not require special handling to prevent the formation of acid mine drainage

Abstract

Ofiolite and metamorphic the oldest rock which found in Obi Island in pre-tertiery age. Contact of both rock estimated as structural contact. Ofiolite consist of peridotite, piroxenite, gabro, basalt, and metabasalt. As for metamorph are schist-mica and phylite. Those rocks especially found in the west side of Obi Island and the minor part found in the outcrops of the south.Peridotite in research area is source rocks which affected by hydrothermal fluids which occur in the end of magmatism processes and change peridotite into serphentinite (peridotite-serphentinite) and this processes known as the beginning of nickel laterite deposit formation process.Mechanical and chemical weathering to the provenance which contain Ca, Mg, Fe, Na, Si, Cr, Mn, Ni, Co, causes this integration and decomposition where those material soluble and then deposited again as somekind of mineraqlsw

Abstract

Ten samples taken from delta front by grab sampler. Sediment grain size of delta front varies from fine silt to fine sand. Acetolyzed method was used to separate fungal spore from sediment. Two methods used to identify of fungal spore i.e. Elsik classifications and fungal classification. Fungal spores in delta front derived from terrestrial and marine. Fungal spore is effective to study deposition environment and paleoenvironment.
