摘要 范疙瘩金矿区位于华北地台南缘华熊台隆之熊耳山断隆区。其特征是区域断裂控制成矿带分布,局部断裂控制金矿床(点)的产出。沿着五丈山岩体接触带以外,1~5km范围内分布。本区内的古火山机构以及围绕着古火山口的环状、放射状构造往往是成矿的有利部位。围绕燕山期花岗岩体的外蚀变带也是找矿的有利靶区。 Fangeda gold ore field is located in the Xiongershan uprise - fault zone of Huaxiang platrform uprise at the south edge of the north China platform, which is characterized by the regional fault control of the ore - forming belt distribution and the local fault control of the occurrence of gold deposits ( sites ) , which are distributed in the area 1--5 km distant from the outside the Wuzhangshan rockmass contact belt. In the area, paleovolcanic structure and the ring and radial structures surrounding the paleovolcanic crater are often the spots favorable for ore forming. The outer alteration zone surrounding the granite rockmass of Yanshan stage is also the target of ore prospecting.
