Abstract

This research concerning about Facies and Sediment Environment of Carbonate Rock in Wonosari Formation. Research located at Goa Jepang site, in Parangtritis coastal areas, Seloharjo Village, Pundong Sub District, Gunungkidul District, Yogyakarta Special Region. Geographic position S 7o59’54’’-8o00’14’’ and E 110o19’43”-110o19’58”. Method of research is including rock outcrop profile and petrography thin section for three observer location in Goa 1, Goa 2, and Goa 3, from 18 location of Goa. There are 18 sites of Goa Jepang and it has three facies of stone unit, wackestone, packstone and framestone. Carbonate stone evolution for faciesof wackestone and packstone be in stabilization zone and it is placing Goa Jepang on the back reef-reef flat of depositional environment zone. However, for Goa Jepand 2nd location with framestone facies has different carbonate evolution to the diversification phase to come reef crest-reef front of depositional environment zone.

Abstract

Coal is one of the energy resources still become the primary needs of strategic energy for sustaining national energy in Indonesia. This study discusses coal existence in Nanggulan Formation at Yogyakarta area. Coal distribution pattern in Nanggulan Formation can provide the geometry conception base on the geological research in Watupuru area encountered three coal outcrop (OC_1, OC_2, and OC_3) stratigraphically is at the bottom layer.Coal distribution in the research area influenced by the pattern of anticline structure which has the position of the wing of East and West with the relative anticline axis of north-south direction. Reconstruction results show there is two-seam of coal, for the first seam layer have 0,55 meters thickness and for the second seam layer have 20,57 meters thickness. Seam 1 of reconstructed surface data has spread on the East side of the anticline. Seam 2 stratigraphically under seam 1 of the reconstruction results indicate that the spread is close to the anticline axis and spreads on the east side of the anticline with a 26o slope and the western wing side of the anticline with a slope 10o.

Abstract

The research is investigating Middle Miocene to Pliocene geological stage of sediment depositional changing in Dusun Beji, Desa Jelok, Kecamatan Patuk, Kabupaten Gunung Kidul, Special Regionof Yogyakarta. Base on the measure section of cross-section analysis and bentonitic fossil analysis, the research area has three formations from old to young formation such as Sambipitu Formation, Oyo Formation, and Wonosari Formation. The result analyzed that microfossil show Sambipitu Formation deposition in the middle of the neritic zone and changedintothe deep neritic zone until lower bathyal in Oyo Formation, and it changes become more shallow in Wonosari Formation, which is depositions in the lower neritic zone to upper neritic zone as long Middle Miocene to Pliocene age. Sambipitu and Oyo Formation havedepositional changing from Lower Fan to Supra Fan Lobes on Mid Fan with lithology change form silt with bioturbation structure to pumice breccia, tuff, sandstone and claystone with slump structure, lamination and massive. In other depositional in Wonosari Formation have environment of Inner Ramp with clastic limestone dominated such as calsirusite and calcarenite.

Abstract

The Oyo River, which stretches relatively northwest - southeast in Beji Village, has seven rock facies that make up the Sambipitu Foundation with marl lithology, then the Oyo Formation is deposited on it with claystone lithology, breccia, tuff and sandstones, and the Wonosari Formation with calcirudite lithology and calcarenite based on stratigraphic measurements as thick as 165 meters with dips ranging from 5o-15o. The variation in the composition of the bentonic foraminifera shell wall in the Oyo River rocks reflects environmental changes from normal marine lagoon and carbonate platforms to a continental slope and sea shelf when referring to the triangular plot of Murray (1991) and Brasier (1980) based on the type of shell composition Loeblich and Tappan (1988). The existence of sedimentary structures also shows a transition from a lower fan in the Sambipitu Formation to a suprafan lobes on the mid fan in the Oyo Formation based on the underwater fan model Walker (1978) and ending up as an inner ramp according to Buchette and Wright (1992) by Tania (2019). This is in line with the depositional environment by Tipsword et.al. (1966) and the foraminifera group by Bignot (1982) which shows that the Sambitu Formation is dominated by porcelaneous in the middle bathyal, then the Oyo Formation is dominated by agglutine in the upper bathyal and the Wonosari Formation on the outer-inner neritic is dominated by porcelaneous.middle bathyal, then the Oyo Formation is dominated by agglutine in the upper bathyal and the Wonosari Formation on the outer - inner neritic is dominated by porcelaneous.

Abstract

Daerah penelitian berada di Perairan Utara Pulau Bangka, tepatnya di Laut Cupat yakni di sebelah utara dan diantara Tanjung Penyusuk dengan Tanjung Melala yang secara administratif termasuk Kecamatan Belinyu, Kabupaten Bangka Barat, Propinsi Kepulauan Bangka Belitung.Akibat intrusi Granit Klabat saat Trias Akhir, terjadi mineralisasi pada Kompleks Pemali melalui Fase Pneumatolitik yang dicirikan oleh kehadiran mineral cassiterite yang tersebar dalam bentuk urat-urat kuarsa dan greisen sebagai sumber timah primer. Akibat proses eksogen yang berupa pelapukan dan erosi seiring dengan naik turunnya muka air laut, timah primer mengalami pemisahan dari batuan sumbernya, kemudian tertransport dan terendapkan sebagai timah plaser dengan geometri mengikuti konfigurasi batuan dasar yang umumnya berupa Perbukitan Terkikis dan Peneplain dari Bentukan Lahan Denudasional.Hasil analisa terhadap data bor dan data seismik menunjukkan bahwa penyebaran gravel (lapisan bertimah) daerah penelitian mengikuti pola pengaliran Dendritik dengan arah relatif tenggara – barat laut dan dikontrol oleh keberadaan batuan granit sebagai batuan sumber serta morfologi batuan dasar yang bergelombang sehingga menghasilkan endapan tipe Kaksa yang berada pada lembah-lembah batuan dasar Laut Cupat.
