This report summarizes the geological knowledge gained to date in the indonesian province of irian Jaya. 'Irian' is a Biak-Numfoor Word meaning a hot land rising from the sea, and 'Jaya' is a Malay-indonesian Word meaning victorious.
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 and Mineral Exploration Project is a technical cooperation scheme between the goverments of the Republic of Indonesia (Ministry of Mines and Energy) and the United Kingdem (Overseas Development Administration). It is carried out jointly by the Directorate of Mineral Resources (Salman Padmanagara, Director) and the Briti…

Guna mengetahui gambaran sebaran sumberdaya mineral khususnya endapan logam di suatu daerah di Indonesia, maka perlu diinventarisasi data yang akurat di setiap tempat. Salah satu cara yang efektif dan murah untuk pelaksanaan maksud tersebut adalah dengan melakukan penyelidikan geokimia regional bersistem.
Tugas dan fungsi seksi geokimia regional antara lain adalah melakukan pemetaan, penyelidikan geokimia regional secara bersistem dalam rangka penyelidikan secara umum serta penyelidikan yang berkaitan dengan aspek geologi, mengembangkan metoda penyelidikan dan menyusun laporan berikut peta sebaran unsur dalam berbagai skala
