摘要:
成矿单元是区域成矿背景、成矿规律研究成果的集中表现,也是矿产勘查及预测评价的基础。根据找矿工作的需要,在全面收集前人研究成果的基础上,以大地构造演化为基础,以区域成矿规律为主线,突出研究区域内地层、构造、岩浆岩带和相关矿产的成矿作用,针对青海成矿构造单元之多样性、复杂性及独特性,系统阐述了青海成矿单元的划分方案。青海成矿单元划分为秦祁昆和特提斯2个Ⅰ级成矿域,北祁连、柴达木盆地、东昆仑、西秦岭西、可可西里—巴颜喀拉、三江北西延6个Ⅱ级成矿省,16个Ⅲ级成矿带和41个Ⅳ级矿带。分析讨论了划分出的Ⅲ级成矿带和Ⅳ级成矿亚带的成矿条件、优势矿种及矿床类型等,为进一步研究青海成矿规律奠定基础,对青海今后区域找矿方向和成矿预测提供指导。
Abstract:
Metallogenetic units show regional mineralization setting and regularity, and are the foundation of mineral prospecting, exploration and prediction assessment. According to the demand for mineral prospecting and exploration, based on the former’s research achievement, in terms of regional tectonic evolution and mineralization regularity of stratigraphy, tectonic, magmatic belt and associated mineral, the metallogenic units in Qinghai were classified systematically, complicatedly and uniquely. The classification of metallogenetic units include 2 Ⅰ-grade metallogenic domains of Qin-Qi-Kun and Tethyan, 6 Ⅱ-grade metallogenic provinces of North Qilian, Qaidam Basin, East Kunlun, the western of West Qinling, Hoh Xil-Bayan Har and the westward extension of North Sanjiang, 16 Ⅲ-grade metallogenic belts and 41 Ⅳ-grade metallogenic subbelts. And then, the mineralization condition, dominant minerals and deposit types of Ⅲ-grade metallogenic belts and Ⅳ-grade metallogenic subbelts were analyzed in order to find the mineralization regularity and provide prospecting direction and metallogenic prediction in Qinghai.
