The Following methoda of analysis are aplicable to the determination of trace amounts of elements important in the geochemical survey of Southern Sumatra. The methods are applicateble to all waters, stream sediments,soils and in some casses rocks and panned concentrates.
Mesozoic-Cenozoic plutonic rock are present throught western sumatra,defining a series of subpararel,fault-controlled,northwest-southest trending belts. regionally they,broadly,correspond to the southerly extension of the western granite province of peninsular Thailand-Burma but some of the creataceous granites focussed along and west of the main su…
The regional geochemical sampling of Siuthern Sumatra was carried out by the Directorate of Mineral Resourches between 1980 and 1992. All result have been published for each quadrangle area as single element proportiional symbol maps at 1:250.000 scale

A Brief mineral investigation was carried out in the Tinjoan area, Sumatra Utara. This took the form of a drainage basin survey which was conducted at a time when the main target area (the Hatapang Granite( was being investigated by the project. No significant mineralisation was seen in the field or is indicated by the drainage basin survey

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 …
