| Summary: | Research area is divided into six geomorphological units, there are: Homoclinal Valley, Homoclinal Ridge, Volcanic Ridge, Folded Ridge, Intrusion Ridge and Alluvial plain. Geomorphology research area controlled by structural geology such as fault, fold and fracture. Stratigraphy of research area is divided into six units, since Late Miosen until Holosen with order of sequence from old to young: Claystone-sandstone, Breccia-sandstone, Claystone, Intrusion, Volcanic Breccia, and Alluvial Deposit. Structural geology occured in the research area are fold with axis direction E-W, and strikeslip fault (dextral strike-slip thrust fault) with direction NE-SW formed in Pliosen-Pleistosen. The Study of sedimentology on Claystone-sandstone show that equivalent with Cinambo Formation and Breccia-sandstone is equivalent with Jatigede Member, both of them deposited in upper bathyal-outer neritic environment with interfingering contact. While Claystone is equivalent with Kaliwangu Formation which deposited in transition-middle neritic environment. Method of sedimentology study through by measuring stratigraphy column. Based on sedimentation analysis, then Claystone-sandstone and Breccia-sandstone have facies A, C, F and G (turbidite facies classification by Mutti dan Ricci Lucci, 1972) while according to turbidite facies classification Walker (1978) both of them have classic turbidites, clast-supported conglomerate, pebbly sandstones and matrix-supported bed fasies which deposited passing by turbidity current mechanism on middle-upper submarine fan. Claystone have mixedflat and mudflat facies (Dalrymple, 1992) passing by suspension current mechanism. |
