新疆阿勒吞塔格南铜铁矿矿床地质特征及成因初探

Study on geological features and genesis of the southern Aletuntage Cu-Fe deposit in Xinjiang

尉犁县阿勒吞塔格南小型铜铁矿床位于塔里木盆地东北缘。通过大比例尺填图、钻探、槽探等工作对阿勒吞塔格南铜铁矿进行了综合评价,认为矿体呈似层状赋存于辉石岩与钾长花岗岩岩体接触带内,受断裂构造控制明显;根据矿床矿化富集特征,划分出岩浆期、热液期和表生期三个成矿期,初步认为该矿床为岩浆热液型矿床。

Yuli County southem Aletongtagan small copper-iron ore deposit is located in Yuli county, Xinjiang, and the northeastern margin of the Tarim Basin. On the basis of large-scale mapping, drilling and trenching geological work, we found that the orebody is layered in the contact zone between pyroxenite and K-long granite, and controlled by the fault structure. And accouding to the enrichment characteristics of the main mineralization elements of the deposit, we divided the mimeralization course into three periods： magmatic period, hydrothermal period and epipassy period. And it is suggesed that the deposit belongs to magmatic hydrothermal type copperiron ore deposit.
