摘要
矿体主要处于上寒武统核桃坪组及寒武纪片麻岩、条痕状混合岩与燕山期花岗岩体的接触带中,断裂破碎带为含锡石石英脉的赋存、富集提供了空间,矿体呈脉状,但其厚度和品位变化较大,属岩浆高温热液矿床。
The ore body is mainly in the contact of Upper Cambrian Hetaoping Formation and Cambrian gneiss, streaky migmatite with Yanshanian granite body. The fault zone provides the space for the existence and concentration of cassiterite-bearing quartz vein. The ore body is veined, which changes very intensely in thickness and grade. It belongs to a magmatic high T hydrothermal deposit.
