概要 |
Majalengka sub-basin is located at the middle part of West Java. This basin, regionally, is part of Bogor trough, a back-arc basin. The basin is sedimentary basin formed during the early Tertiary. Get...ting into the middle to late Miocene, sedimentation in this basin was dominated by a turbidite derived from multiple-source, Northwest Java basin in the north and South Mountain in the south. The occurrence of organic matter in this basin is estimated from the north sedimentation source. Based on rock-eval pyrolysis and vitrinite reflectance methods shows that the hydrocarbon source potential is dominated by immature to mature and gas prone type III kerogen. This kerogen type is mainly composed as a product from terrestrial material deposited into deltaic to shallow marine. Preservation of organic material in turbidite is interpreted as results from resedimentation or sedimentation transportation through the channel systems. In addition, magmatism and tectonism is the main parameter to generate organic matter become hydrocarbon.続きを見る
