| 摘 要： | 冯昌金矿区位于河北省武安市东北部。利用重砂、水系沉积物测量和土壤地球化学找矿方法，通过对武安冯昌一带系统扫面和重点加密工作和1：1000比例尺填图，找到十余处含金蚀变矿化带。根据探槽取样分析数据圈定出5个金矿体。矿体产于闪长（玢）岩外围的三叠系长石砂岩破碎带中，褐铁矿化是地表的找矿标志。该类金矿是河北省金矿类型中少见的一种较特殊的类型，对其深入探讨和研究有重要的理论意义和找矿意义。

| Abstract: | Fengchang gold field is located in the northwestern part of Wu'an city,Hebei Province.More than 10 gold-bearing alteration-mineralization belts were found with the methods of heavy minerals,stream sediment survey and 1/1 000 geological mapping.5 gold orebodies were outlined according to the analysis data of the prospecting trench samples.The orebodies developed in the Trias arkose fracture belts outside the diorites.The limonite is the criteria for ore prospecting.This kind of gold ore is an especial one in Hebei Province and is very important to study the gold ore in this area for further prospecting. |
