The area consists mainly of a sequence of clastic metasediments,limestones and metavolcanics known as the Geumpang Formation, Which forms part of the Woyla Group of late Jurassic to Early Cretaceous age.To the South-east this succession is cut by the Anu-Batee Fault, a major splay of the North Sumatra Fault System that strikes NW-SE down the axial l…

The kr. Dusun area of Aceh Tengah has been the subject of several previous mineral investigations that have indicated the presence of mineralisation, possibly in the form of a molybdenum prophyry copper with associated lead-zinc mineralisation. This investigation has shown the Dusunintrusive complex is more extensively hydrothermally altered and tha…

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 survey area lies 90 Km northwest of Tapaktuan on the west coast of Sumatra in Aceh Province. A regional geological and mineralisation. The Susoh instrusion (late cretaceous to palaeocene in age)intrudes volcanics and limestones presenting the possibility of skarn-type mineralisation. Also the drainage basin survey had indicated copper anomalies …

The Dusun Intrusive complex, which lies about 40 km southeast of lake tawar in a remote part of Aceh Tengah, has been the subject of a mineral investigation programme. Previous investigations in this area have revealed the presence of chalcopyrte, galena,sphalerite and molybdenite, with indicatations of both porphyry-style and vein mineralisation.…

Three low priority areas were investigated in the Takengon quadrangle because of their proximity to a more important area being studied. These areas-Panomon, Kebyaran and keuretu -were suggested as follow-up targets on the basis of geochemical anomalies found during the regional geochemical survey of the north Sumatra Project (NSP).
The North Sumatra Geochemical adn Mineral Exploration Project (NSGMEP) is a 4 year (1984-1988) mineral exploration programme being undertaken by a combined team of geologist seconded from the British Geological Survey (BGS) and Counterpart from the Directorate of Mineral Resources (DMR), Indonesia
