| Summary: | Prospect Cu - Gold Bulagidun located in North Sulawesi district having climate warmness and wet. By using data logbor and does modelling, can be analysed typical of deposit porfiri - Cu Au. The deposit is deposit type porfiri Cu - Diorite model gold that is usualy is formed in Island Arc. Typical primary mineral in district is magnetite, pyrites, and chalcopyrite.<p>The result of data analysis logbor is continued with ore microscopy study, result of data analysis which in the form of existence of limonite simply elaborated becomes existence of goethite mineral and lepidokrokit. While from some samples which at data logbor is calcocite which compared to result of reconnaissance of its the ore microscopy is calcocite and flirtatious other mineral are kovelit ,malasit and natif Cu. Mineral lepidokrokit is differing from goethite mineral, based on result of microscopy study, the mineral typical of evidence existence of soil water fluctuations happened at prospect district in certain time period.<p>From result of modelling can be analyzed that secondary enrichment zone formed enough of thickness around 7.6 meter. The condition is result of existence of trouble happened during process - forming process. The trouble as result of already the happening of water table fluctuations, soil,land;ground avalanche that is large, and existence of activity vulcanic. |
