新疆西天山金矿成矿条件分析及找矿远景预测

本文通过对西天山研究区的遥感地质解译、野外实地验证和综合对比研究，认为西天山地区与邻区的穆龙套金矿、库姆托尔金矿同处一条巨型的构造带上，具有非常相似的大地构造环境、构造演化和赋金建造条件，尤其是分布于那拉提构造带南缘的弧形构造带和南北向贯穿那拉提构造带的横向断裂组是控矿的重要因素。区域上赋金层炭质岩系的存在和蚀变体的广泛发育，使金元素活化、富集成为可能。研究区内大量的金矿化、异常是金矿体存在的客观反映。据此，笔者预测出４处找矿有利地段。

ANALYSIS OF GOLD METALLOGENIC CONDITIONS AND PROGNOSIS OF METALLOGENIC PROSPECT OF WESTERN TIANSHAN,XINJIANG AUTONOMOUS REGION

Based on the interpretation of remote sensing images of the western tianshan area,the field checking and the comprehensive comparison the author suggests that the western Tianshan area is located in the same mega tectonic belt as the Muluntao and Kumtor gold deposits area,having very similar tectonic environment,tectonic evolution and gold hosting formation.Especially,the arc shape structural zone located at the southern margin of the Nalati tectonic belt and Lateral NS trending faults intersecting the Nalati tectonic belt are important ore controlling factors.The occurrence of gold rich carbonaceous rock series and the extensive development of altered rock bodies in the region made the mobilization and concentration of gold possible.The oceurrence of numerous gold mineralizations and anomalies in the study area are objective indications of gold deposits in the region.Finally,4 favourable prospecting sites are predicted according to the analysis on gold metallogenic conditions.
