Penelitian serpih bitumen merupakan proyek inventarisasi sumber daya energi,lembaga Geologi dan pertambangan Nasional-LIPI di daearah Sumatera Barat dalam tahun anggaran 1981/1982.
Dengan adanya informasi mengenai adanya endapan batugamping dan batubara didaerah kecamatan bangko dan sungaimanau, kabupaten sarko, Propinsi Jambi, maka diadakan penelitian mengenai endapan tersebut. Baik secara geologi maupun pertambangan dan batubara dapat digunakan sebagai bahan baku industri besar,sedang dang kecil(rakyat).
The area surveyed is dominated by pretertiary Woyla Group Rock Consisting of a succession of volcanics and sediments with calcareous units. This group is intruded by the miocene geunteut granodiorite.There have been several previous mineral investigations of this area producing conflicting conclusions.Streams not previously sampled give good geochem…

The Baso Granodiorite instrusion, which lies just north of the Sumatra fault zone in a remote part of Aceh Barat, has been the subject of a two-fold mineral exploration investigation. The instrusion and its environs were investigated as a potential source of gold and secondly there were a number of regional geochemical survey anomalies, particularly…

The Hutabargot survey area is a few kilometers west of kecamatan panyabungan on the western side of the batang gadis river. The region was investigated in 1978 as part of the NSP and during this time occurrences of Cu,Pb,Zn,Au and Ag were recoreded in the Tertiary volcanics. This present survey was to investigate geochemical anomalies found during t…
The main objective of this present survey was to outline mineralised areas and determine the nature and significance of mineralisation found during the NSP work. Systematic sampling involving the collection of geochemical samples was carried during the field work.The oldest rocks in the Sijorang area are hornfelsic metasedimens,limestones,metavolcan…

During the course of the north sumatra project (NSP), three quality control reference materials were used GS-1.GS-2,GS-3. The samples were made by collecting a local (lembang) pozzolona derived from andesite to give the low level control sample GS-1. Porions of this material were then spiked with natural minerals to provide GS-2 (AAS high level stan…
