新疆喀喇昆仑成矿带成矿规律概论

西昆仑地区的喀喇昆仑成矿带是我国具有较大找矿潜力的重要远景区,目前已成为西部铁铅锌矿产勘查开发的热点地区之一。本次根据该区域地质建造和成矿特征,借鉴我国地质学家创立的矿床成矿系列理论,对喀喇昆仑成矿带的成矿系列进行了深化研究。按照成矿作用与地质建造的时间关系,将成矿系列细化为同生、后生和表生风化等类别。同一套地质建造有关的几个世代的成矿系列自然地构成一个成矿系列家族(简称成矿系列族)。在喀喇昆仑成矿带初步总结出9个成矿系列族和12个成矿系列。在此基础上,通过成矿谱系,从构造演化角度探讨了各成矿系列及家族形成的背景,为阐明区域成矿规律奠定了基础。

Generality on Metallogenic Regularity of Karakorum Metallogenic Belt in Xinjiang

Karakorum metallogenic belt is one of the hot area for the mineral resource exploration and development in West China with a great prospecting potential.According to the metallogenic theories established by the geologists of China,Karakorum metallogenic belt are further researched based on the metallogenic characteristics and its feature of geological formation. In the light of the time-space relationship of the mineralization and the geological formation,the related metallogenic series can be divided into syngenetic,epigenetic,and superficial weathering metallogenic series.These metallogenic series existed in the same geological formation naturally constitute a metallogenic serie family.In this study,9 metallogenic serie families and 12 metallogenic series are summed up for the main mineral deposits of Karakorum metallogenic belt.On the basis of the mineralization pedigree,from their tectonic evolution angle,we further discussed its dynamic background of the formation for the metallogenic serie families,which provides the basis for clarifying the regional metallogenic regularity.
