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…
