迁安市长城金矿地质特征及找矿标志

摘要：迁安市长城金矿矿床属于构造蚀变岩型金矿床，赋存于蓟县系杨庄组（Jxy）白云岩及部分蚀变闪长玢岩岩脉中，呈脉状、似层状产出，主要受断裂或构造破碎蚀变岩带控制。随着勘查与开发的深入，人们对长城金矿的认识更加全面。本文结合长城金矿的地质特征，分析其找矿标志，以更好地开发金矿资源。

Abstract： The Great Wall Gold Deposit in Qian’an City belongs to the tectonic altered rock type gold deposit， which occurs in the dolomite and some altered diorite porphyrite veins of the Yangzhuang Formation of the Jixian System （Jxy）， it is produced in a vein like and layered manner and is mainly controlled by faults or tectonic fractured altered rock zones. With the deepening of exploration and development， people’s understanding of the Great Wall Gold Mine has become more comprehensive. Based on the geological characteristics of the Great Wall Gold Deposit， this paper analyzes its prospecting criteria， in order to better develop gold resources.
