Abstract

Cisadane Watershed is one of the most rapidly growing areas and infrastructure development, and has developed as a residential, industrial, administrative centers and other economic activities. The purpose of this paper is to use remote sensing satellite imageries to identify the morphotectonic characteristics of the Cisadane watershed both qualitatively and quantitatively. Processing stereomodel, stereoplotting and stereocompilation on TerraSAR-X Digital Surface Model (DSM) and SPOT 6 imageries, produced the  Digital Terrain Model (DTM) image, which has not been affected by land cover. Fusion of the DTM  and Landsat 8 RGB 567+8 images  is used to interpret the distribution of lithology, geomorphological units, and lineaments, which are an indication of geological structures. The morphotectonic characteristics of sub-watersheds qualitatively was carried out a bifurcation ratio calculation (Rb) which indicates tectonic deformation. Based on the analysis of satellite images both qualitatively and quantitatively, the morphotectonic characteristics of the upstream, middle and downstream Cisadane Watershed have been deformed.Keywords : satellite images, morphotectonic, DSM, DTM, Cisadane Watershed.

Abstract

Geologi suatu daerah sebagai suatu model dapat mengalami perubahan secara konstruktif (refining), sejalan dengan munculnya gagasan-gagasan baru dalam sedimentasi, stratigrafi, tektonik dan evolusi cekungan, serta vulkanisme, didukung oleh berbagai jenis data baru yang lebih banyak dan lebih akurat. Suatu kolase elemen-elemen dasar yang disusun secara lokal dan dihubungkan satu dengan yang lain menurut kaidah yang dianut akan membentuk pengertian baru. Penelitian ini merupakan hasil pengamatan geologi lapangan ditunjang dengan pekerjaan studio, khususnya dalam interpretasi struktur geologi. Klasifikasi genetik terbentuknya cekungan Kuarter, selanjutnya dibangun dan mengacu juga kepada kontrol struktur terhadap penyebaran batuan vulkanik Kuarter dan gunugapi aktif di Jawa Barat. Atas dasar analisis, pembentukan cekungan pada area studi merupakan cekungan antar pegunungan di Jawa Barat, secara umum dapat dikelompokan menjadi: Anticlinal collapse basin, Half Grabben Basin, Flexure Subsidence Basin, Pull Apart Basin dan Paleovolcano Crater Kata kunci: Jawa Barat, Pembentukan cekungan, Tektonik, volkanisme

Abstract

Volcanoclastic sediments commonly represent low quality reservoir facies, since volcaniclastics are composed largely of reactive and unstable minerals that leads to the destruction of porosity by cementation and compaction processes. During the Neogene time, although the Bogor Trough largely infilled by volcaniclastic deep-water deposits, the arenites that delivered from continental in the north actually still contributed as sequel Paleogene deposits. This manuscript intends to discusses the Neogene provenance of continental sediments  into the Bogor Trough. The samples are taken from sandstone beds of the Cinambo Formation at Cilutung River in Majalengka. Quartz-rich sandstones are better potential reservoirs in term of quality in hydrocarbon exploration of sub-volcanic region in this area.
