摘要
矿床含两条脉状物,分别赋存于燕山晚期第一阶段(V1)和第二阶段(V2)花岗岩云英岩化带中,V1为半风化、全风化铌钽矿,V2则为原生锡矿。共生黑钨矿、白钨矿。成因与构造、中酸性侵入岩密切相关。
The ore deposit consists of 2 veined ore bodies,which are separately in the greisenization zone of the first（V1） and second（V2） stage granite of Late Yanshanian.The V1 is the semi-weathering Nb-Ta deposit,whereas the V2 is the original Sn deposit.The paragenetic minerals include wolframite and scheelite.The genesis is close related with the structure and intermediate-acid intrusive rock.
