河南省方城县漆树沟矿区风化型矿床特征及成因探讨

Characteristics and genesis of weathered granite type potassium-feldspar deposit in Qishugou Gold Mine, Fangcheng County, Henan Province

漆树沟矿区区域大地构造位置位于华北地台南缘,秦岭地轴北侧,属北秦岭地层区豫西南分区。区域内褶皱简单,断裂构造发育,主要以阎家庄～龙王庄背斜和北西～南东向断裂为主。钾长石矿的矿体围岩为风化花岗岩,燕山晚期侵入岩似斑状黑云母二长花岗岩,是寻找矿床的标志。

The regional geotectonic location of Qishugou mining area is located on the Tainan margin of North China, North of the Qinling axis, and belongs to the Southwest division of Henan Province in the Northern Qinling Formation. The fold in the area is simple and the fault structure develops. The main faults are the Yanjiazhuang-Longwangzhuang anticline and the northwest-south East direction. The surrounding rocks of potassium feldspar ore are weathered granites, and the late Yanshan intrusion into the speckled black mica two-long granites is a sign of finding deposits.
