| Abstract: | The Precambrian gold deposits in central Hunan Province,distributed mainly in the Baimashan-LongshanZiyunshan E-W-trending tectonomagmatic belt,are with different mineral assemblages including Sb-Au,Sb-As-Au and As-Au.The gold deposits are mainly of fracture zone altered rock type,with minor quartz vein type.The orebodies occur within or near the exocontact of intrusive rocks and above the hidden igneous rocks.The genesis of the gold deposits belongs to metamorphic hydrothermal type and thermal contact metamorphic hydrothermal type.The regional metallogenetic regularity is obvious,with distinguishable ore-forming indicator for prospecting. |
