The Typomorphic Feature of Pyrite and Metallogenic Prognosis at GA Area in Neglasari Gold Deposit of Indonesia West Java Area

Pyrite is the most common metal mineral in gold deposit.It not only has a close relationship with the gold mineralization,but also is the main gold-carrier.The crystal form typomorphism of pyrite at GA area in Neglasari gold deposit is mainly analysed.From the study,it is found the crystal form of pyrite in this area are relatively simple,it shows nearly the crystal of {100}、{210}、{111} and their combination and irregular shape.Based on the relationship between the morphology of pyrite and the mineralization intensity,a summary of the typomorphic feature of pyrite and the gold mineralization is presented.
