From 1976 through 1982 intensive systematic geological mapping Was carried out in Irianjaya, the easternmost provice in indonesia, in the western oart of the island of new guinea. Concurrently, sporadic geochemical sampling Was performed in minland Irianjaya and the nearby island.
A hydrothermally altered granodiorite containing molybdenite and chalcopyrte, dicovered by AMAX mineral exploration, has been investigated by rock and detailed drainage basin sampling. This well-exposed mineralisation is found in the Alue Moli, a small tributary of the Kr. Ise-ise, not far from the Takengon-Blangkejeren track, some 108 km south of T…
Pemetaan geologi di lembar Biak, Irian Jaya, di lakukan pada tanggal 15 oktober hingga 28 Desember 1977 oleh sub Direktorat Perpetaan, Direktorat Geologi (sekarang Pusat Penelitian dan Pengembangan geologi), melalui Proyek Pemetaan Geologi dan Interpretasi Foto udara. Hampir semua perlengkapan lapangan termasuk kendaraan bermotor dan perahu bermotor…
Prior to the IAGMP the only significant gravity mapping of Irian Jaya Was undertaken byb the Nederlandsche Nieuw Guinee petroleum Maatschappij(NNGPM) from 1936 to 1960 as reported by visser and Hermes 1962. This pioneering Work Was undertaken as part of a search for oil and gas Was therefore largely restricted to areas of considered hydrocarbon pote…

The Kr. Dusun basin area has been subjected to several previous investigations that have indicated the presence of porphyry-style mineralisation plus the occurrence of some lead-zinc drainage basin anomalies. In this investigation an area a altered granodiorite was surveyed by detailed drainage basin and rock sampling.

The Ransiki 1:250,000 geological sheet is bounded by 1 derajat and 2 derajat sounth latitudes and 133 derajat and 134 derajat 30' east longitudes, and overlaps the eastern coastline of the Birds Head of Irian Jaya, indonesia's easternmost province.
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.
