Abstract

Mamuju is a Miocene volcanic complex and become the location of the exploration of radioactive and rare earth elements. These area composed by basaltic and volcanic rocks up to intermediate with ultra potassic and soshonitic afinity. Magmatism processes in this area is a multi-phase process, there by producing a hydrothermal flows through rock porosity and fracturation zone. Hydrothermal fluid interacts with the rock side. Hydrothermal process is very influential volcanic central area of and areas with intensive fracturation. The rocks in these areas experiencing strong alteration to produce a very thick layer of soil, and in some places formed is very intensive mineralization and sulfidation and oxidation. Alteration encountered in the form of the potassic alteration minerals such as biotite paragenesis, actinolite and plagioclase, and formed titanite and adularia. Mineralization and levels of radioactive elements and rare earth elements have a higher concentration on the fracture-fracture and the autoclastic breccia.
