新疆木垒县喀拉沙特金矿地质特征及成因

喀拉沙特金矿产于构造破碎蚀变带中。通过普查工作共圈定2个金矿体和1个金矿化体，I号金矿体产状25。＜84。，长80m，水平厚度0．12～2．40m，倾向延深111．40m。品位1．63×10“～2．98×10－^6，平均品位1．62×10一^6。Ⅱ号金矿体产状168。么82。，长80m，水平厚度0．80～1．02m，平均厚度0．91m，倾向延深115．27m，品位1．72X10一^6～4．44×10一^6，平均品位2．83X10一^6。通过对矿床地质特征的研究，认为该矿床属沉积一变质型金矿床。

Geological Characteristics and Origin of Gold Deposit in Kalashate in Mulei County in Xinjiang Uygur Autonomous Region
