福建建瓯坤口—石呈地区钨钼多金属矿找矿远景分析

Analysis on Prospecting Prospect of Tungsten-Molybdenum Polymetallic Ore in Kunkou-Shicheng of Jianou City,Fujian Province

通过建瓯坤口—石呈地区1∶5万矿产远景调查研究,发现区内与钨钼矿有关的矿床类型主要为中高温热液型,与成矿相关的地质体主要为晚侏罗世侵入岩及新元古代变质岩。综合分析成矿地质条件、成矿作用,总结区内找矿标志,认为以钨钼为主的多金属矿是该区的主要成矿类型,并圈定了成矿远景区。

Based on the investigation of mineral prospect of 1:50 000 in the Kunkou-Shicheng area of Jianou city,it is found that the type of deposit is mainly of medium and high temperature hydrothermal type which related to tungsten and molybdenum deposits in this area.The ore-forming related geological bodies are mainly late Jurassic intrusive rocks and Neoproterozoic metamorphic rocks.Based on the comprehensive analysis of metallogenic geological conditions and metallogenic processes,summarized the prospecting criteria,it is considered that the tungsten and molybdenum polymetallic ore is the main metallogenic type in this area and the metallogenic area is delineated.
