摘要
五亩山地区燕山期花岗岩侵入活动后,形成了高温热液裂隙石英脉型黑钨矿(白钨矿)矿床。矿化脉体多分布在区域断裂的裂隙构造中,矿化体在地表以中(或低)角度产出,向下以高角度产出,或者两者交替产出形成类似于倾斜的"阶梯"状。通过对含矿裂隙的测量和统计,确定了成矿前或成矿期的裂隙,NE向裂隙为钨矿的容矿构造,并提出了找矿方向。
Hypo-thermal granite in the Wumushan tungsten deposits came into being after intrusion of ore-bearing Yanshanian area. These mineralized vein bodies are usually distributed within fractures of regional fault with medium or low dip angle near surface and high angle bellow or their alternating occarrences. The preminerogenic and syn-minerogenic fractures are defined by measurement and statistics of the ore-bearig fractures. The NE fractures host ore thus the ore-searching direction is pointed out.
