| 摘 要： | 青田县石平川钼矿床是浙江省现已发现的规模最大的钼矿床，多数人认为石平川钼矿床的形成与钾长花岗岩有密切关系。本文主要从岩相学、岩石地球化学、LA—ICPMS锆石U—Pb年代学等方面研究石平川钾长花岗岩，并探讨其成岩环境及成因。研究表明，石平川岩体属于高钾钙碱性、弱过铝质S型花岗岩，其形成于早自垩世晚期挤压环境，源岩物质主要是壳源，并有少部分幔源物质成分参与。

| Abstract: | Shipingchuan Mo-deposit in Qingtian county is a biggest molybdenum deposit in Zhejiang province at present, and most of researchers consider that the genesis of this deposit is closely related to the K-feldspar granite. This paper studies petrography, petrogeochemistry, LA-ICPM zircon U-Pb geochronology of the K-feldspar granite to approach its diagenetic environment and genesis. The study shows that the Shipingchuan K-feldspar granite belongs to high potassium calc-alkaline, weakly peraluminous S-type granite, which was formed in compressional environment in the late of Early Cretaceous. The original materials of the granite mainly came from the crust and some mantle-derived materials were involved. |
