摘要
位于塔里木西南缘的木吉—大同—库地金铜成矿带是西昆仑地区重要成矿带 ,带内金矿主要产于碳质千枚岩、碎屑岩及绢云母石英片岩等岩石中 ,受韧性剪切带及构造蚀变带控制。铜(金 )矿化与华力西期花岗岩类关系较紧密 ,金铜找矿以海相喷流沉积型铜 (金银 )矿、斑岩及夕卡岩型铜金矿、构造蚀变岩型金矿及韧性剪切带型金矿为主。根据金铜成矿环境分析 ,认为该区的金铜矿找矿潜力巨大。
Muji-Dat on g-Kudi gold copper ore belt located in the southwest of Tarim basin is a major ore belt in the west kunlun area. Gold ore deposits mainly occur in carbonaceou s phyllite, clastic rock and sericite-quartz schist and are controlled by ducti le shearing zone and tectonic alteration zone. Copper (gold) deposits are closel y related to Hercynian granitic intrusives. In the area gold ore searching proj ects should be aimed at ductile shearing zone-controlled and altered cataclasti c rock type gold deposit, copper (Au,Ag) ore searching at Sedex type, porphyry type and skarn type. Metallogenic setting analysis of the area show big potentia l for gold and copper ore mineral resources.
