新疆木垒县喀拉沙特金矿地质特征及成因

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

摘要:

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1.63×106～2.98×106，平均品位1.62×106。Ⅱ号金矿体产状168°∠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1.72×106～4.44×106，平均品位2.83×106。通过对矿床地质特征的研究，认为该矿床属沉积变质型金矿床。

Abstract:

Kalashate gold deposit located in structural fractural alteration belt. Through general survey, two gold deposits and two gold orebodies have been circled. The occurrence of Ⅰ gold body is 25 ° ∠ 84 °, the length is 80m, average thickness is 0.12~2.40m, and extending depth is 111.40m. Its grade is 1.63×10-6 ~2.98×10- 6, average grade is 1.62×10- 6. The occurrence of Ⅱ ore body is 168 ° ∠ 82 °, the length is 80m, standard thickness is 0.80~1.02m, average thickness is 0.91m, extension depth is 115.27m, grade is 1.72×10-6 ~4.44×10 -6, and average grade is 2.83×10-6. Through study on geological characteristics of this deposit, it is regarded that this deposit belongs to sedimentary-metamorphic type.
