摘要 八百垅钼多金属矿床地处辽宁省西部,位于华北地台(中朝准地台)北缘山海关―北镇古隆起与辽西凹陷之间的过渡带上,即著名的八家子―杨家杖子岩浆热液钼多金属成矿带的北东部。八百垅钼多金属矿床规模较大,矿床品位高且变化稳定,矿体埋藏较浅,其形成经历了长期的成矿作用和矿化富集,具叠加成因特点,成矿时代为早侏罗世中期,成因类型为高硅、富钾斑岩型脉状、细脉状钼多金属矿床。 Babailong Mo polymetallic deposit is located in western Liaoning Province.The deposit occurs on the transitional zone between Shanhaiguan-Beizhen palaeohigh and Liaoxi Sag on the northern edge of North China Platform,which is known as Bajiazi-Yangjiazhangzi magmatic hydrothermal type molybdenum poly-metallic metallogenic belt.Being characterized by large scale,high grade,stable variation and shallow burial depth of the orebodies,the deposit is formed through long-term mineralization and enrichment,hence the de-posit is featured by superposition with multiple genesis.The deposit is formed in the middle of early Jurassic epoch,and in terms of genetic type the deposit is a high-silicon,rich-potassium porphyry type molybdenum polymetallic deposit which occurs as vein-like or fine vein-like in form.
