Karakteristik dan Diagenesis beberapa Percontoh Batuan Oil Shale Formasi Kasiro Terpilih, di Jambi dan Sumatera Selatan berdasarkan Scanning Electron Microscope (SEM)

Mohammad Heri Hermiyanto, Hermes Panggabean

Abstract


Oil shale, as one of alternative energy resources, is recognized in the Late Eosen - Oligocene Kasiro Formation, located in the Rawas Ulu and Batang Asai areas. Based on SEM analysis, the shale  consists of smektite-illite, illite,  kaolinite, organic matter as liptinite (sporinite,and alginite) and contains oil droplet.The oil shale is composed of smectite-illite and illite characterised by wavy parallel fissile,while kaolinite clays show irregular shape characters. The shale has undergone a diagenetic process within an early mesodiagenetic level. Organic matter maturity level of the oil shale, in general, is the immature up to early mature.

 

Keywords : oil shale,clay minerals,smectite-illite,  organic matter
