新疆鄯善地区彩霞山铅锌矿大比例尺成矿预测

彩霞山铅锌矿是中天山地区目前发现的唯一一个储量有望达到大型规模的沉积改造型铅锌矿床。成矿与青白口系卡瓦布拉克群第一岩性段碎屑岩-碳酸盐岩建造、华力西期岩浆热液活动、区域性阿奇克库都克断裂及其次级断裂有关。矿体的定位与地质异常有关,可通过定量圈定地质异常单元来对矿体进行预测定位。通过对矿区地质异常进行定量研究,对矿区进行了大比例尺成矿预测。预测结果表明,彩霞山矿区有较大的找矿潜力。

Large scale metallogenic prognosis in Caixiashan Pb-Zn deposit, Shanshan area, Xinjiang, China

Caixiashan deposit, which belongs to sedimentary alteration type, is the only large Pb-Zn deposit in middle Tianshan area at present. Clastics and carbonate formation which is in the first member of Kawabulake group, magmatic hydrothermal of Variscan and sub-faults of Aqikekuduk fault control the forming of the deposit. The positioning of ore bodies is correlated with geo-anomaly. Mineral prediction could be conducted by the delineation of geo-anomaly units. Through the quantative study of geo-anomaly, large scale metallogenic prognosis was completed in Caixiashan deposit, which proved that there were great potential for mineral exploration in the area.
