摘要
弄屯矿床是西大明山地区新发现的规模最大的铅锌矿床,是受断裂控制的典型热液脉型矿床。文章在充分搜集已有勘查资料的基础上,认为铅锌矿体主要受NE向和(近)EW向断裂控制,矿体主要产在断裂浅部产状较缓的部位,向深部断裂产状变陡,矿体厚度减薄直至尖灭;而且主矿体沿NE向断裂具有向SW侧伏的趋势。在此基础上,利用控矿断裂的擦痕、阶步以及伴生的节理、牵引褶皱等小构造,对控矿断裂的运动学和动力学特征进行了解析,分析认为控矿断裂在成矿期表现为逆断层活动特征,是受近SN向主压应力作用下形成的。利用SPSS、Surfer软件对矿体的产状、有用组分含量等数据进行统计分析并绘制了等值线图,研究得出成矿热液是先由F1断裂进入NE向断裂中,随后沿NE向断裂由西南向北东运移,并最终导致Zn、Pb先后沉淀富集形成厚大的矿体。根据已有的同位素数据和构造解析资料,可基本确定弄屯铅锌矿床形成于燕山晚期。
        The Nongtun deposit is the largest Pb-Zn deposit discovered in the Xidamingshan area, and is also a typical hydrothermal vein type deposit controlled by fault. On the basis of fully collecting the existing exploration data, the authors hold that the Pb-Zn orebodies are mainly controlled by the NE-and nearly EW-trending faults, and the orebodies are mainly produced in the shallow part of the faults where the dip angle is relatively smooth, whereas in the deep part of the faults where the dip angle is steep, the thickness of the orebody is thinned until termination. The main orebody along the NE-striking fault tends to plunge southwestward. On such a basis, the kinematic and dynamic characteristics of ore-controlling faults were analyzed by using scratches, steps and associated joints, traction folds and other small structures of ore-controlling faults. The results show that the ore-controlling faults are characterized by the reverse fault activity in the ore-forming stage, which was formed by the nearly SN-striking compressive stress. Using SPSS and Surfer software, the authors made statistical analysis of orebodies' attitude and useful component content and drew the contour map. It is concluded that the ore-forming hydrothermal fluid migrated from F1 to NE-striking fault, then migrated from SW to NE along the NE-striking fault, and eventually formed the thick orebodies by the precipitation of Zn, Pb. Based on the existing isotope data and structural analysis data, it can be basically confirmed that the Nongtun Pb-Zn deposit was formed in the late Yanshanian period.
