摘要
新寨锡矿矿体呈似层状、透镜状赋存于中寒武统田蓬组第三段(∈2t3)中,矿体顺层产出,含矿围岩为石英云母片岩、绿帘石化矽卡岩。该锡矿床的形成与老君山燕山期花岗岩侵入关系密切,为层控岩浆期后热液矿床。
The ore body of Xinzhai Sn deposit is stratoid, lenticular in Middle Cambrian Tianpeng Formation 3rd member （∈2t3） . The ore body is in bedding occurrence. The ore-bearing wall rock are quartz mica schist, epidotized skam. The formation of this Sn deposit is in close relation with Laojunshan Yanshanian granite intrusion. It is a stratabound postmagmatic hydrothermal deposit.
