吉林省“三稀”元素矿床成矿特征及找矿前景

“三稀”矿产资源调查已上升为国家战略。在全国开展的矿产地质志研编基础上,全面总结吉林省“三稀”矿产的基本特征,根据“中国矿产地质志”矿床类型划分方案,将“三稀”元素矿床划分了岩浆作用、变质作用和沉积作用3个二级分类和11个三级分类,并分析了各类型矿床的资源潜力。研究表明,富碱侵入岩带是寻找“三稀”矿产的重要靶区,长白山天池周围新近纪碱性火山岩为“三稀”矿产重点研究区,松辽盆地中生代火山岩蕴含“三稀”矿产潜在资源,油页岩、钼矿、煤矿中共伴生的“三稀”矿产资源具有一定远景,应加强综合评价。

Metallogenic characteristics and prospecting potential of "three rare" elements deposits in Jilin Province

"Three rare" mineral resources investigation has become a national strategy.This paper summarizes the basic characteristics of "three rare" minerals in Jilin Province based on the national study and compilation of mineral geology,divides the "three rare" elements deposits into 3 secondary classifications:magmatism,metamorphism and sedi -mentation,and 11 tertiary classifications according to the classification scheme of deposit types in "geology of mineral resources in China",and also analyzes the resource potential of various types of mineral deposits.The study shows that the alkali-rich intrusive rock belt is an important target area for searching for "three rare" minerals,and the Neogene alkaline volcanic rocks around Changbaishan Tianchi are the main research region for "three rare" minerals;the Meso -zoic volcanic rocks in Songliao Basin contain the potential mineral resources of "three rare",the mineral resources associated with oil shale,molybdenum mine and coal mine have a certain prospect and comprehensive evaluation should be strengthened.
