Abstract

Abstract:

The study of genetic mineralogy of pyrite could provide the important information for the estimation of deep mineralization potential.The deep drilling （ZK96-6，2 735.70 m） at the Sanshandao gold deposit uncovered that the mineralization could still extend to the depth （-2 613 m to -2 684 m） along the Sanshandao fault zone.Therefore，this study will focus on the genetic mineralogy of pyrite from the deep drill of Sanshandao gold deposit （-2 613 m to -2 684 m），exploring the indicators of typomorphic characteristics of deep pyrite for the deep mineralization.The detailed observation was given to the geometry typomorphic characteristics of different stages of pyrites.The contents of the major and trace elements of different stages of pyrites were analyzed by electronic probe and ICP-MS，respectively.The thermoelectrometry apparatus was operated in order to explore the thermoelectric characters of all stages of pyrites.The pyrite of quartz-gold-pyrite stage in deep gold orebody shows larger grain size than pyrite in other stages, which indicates that ore-forming fluids in this stage attained the supersaturation condition and amounts of pyrite precipitated.A lot of reduced sulfur could be fixed into pyrite，which led to the destability of Au-S complexes and gold precipitation.Selected trace elements contents of pyrite in deep gold orebody （-2 613 m to -2 684 m） were drawn in the （Au+Bi+Cu+Pb+Zn）-（As+Sb+Ba+Ag+Hg）-（Ti+Cr+Co+Ni） triangle discrimination diagram，which indicates gold orebody in this location belongs to the middle part of the whole orebody and the depth still has the gold mineralization potential.The occurrence rate of P-type pyrite and the gold grade show positive correlation，which indicates that the coprecipitation of P-type pyrite and gold.This relationship could be used as the criterion for the deep prospecting of gold and also indicate the enormous potential of gold mineralization in the depth of Sanshandao gold deposit.
