太山庙地区锡矿地质特征及找矿前景

Geological Characteristics and Prospects of Tin Deposit in Taishanmiao Area, Western Henan Province

太山庙地区锡矿床位于燕山晚期太山庙花岗岩体与中元古界熊耳群安山岩的内外接触带上。矿床受一定的构造、岩浆岩控制,呈不规则细脉及网脉状分布于花岗岩枝伸入安山岩内的构造破碎带中,矿脉规模小,数量多,有必要进一步工作,期待较大型锡矿床的发现。

Tin deposit in Taishanmiao area of Henan Province is located in the inside and outside contact zone of the late Yanshanian period (Jurassic) granitoids and the volcanic rocks of the Mesoproterozoic Xiong'er group, and controlled by a certain structures and magmas. The ore veins with the irregular stringer or stockwork shapes are distributed in the tectonoclastic belt, where the granite apophyses have intruded into andesite. The ore veins are small with a great densitiy, showing potentiality worthy of the further exploration.
