遷安市長(zhǎng)城金礦地質(zhì)特征及找礦標(biāo)志

摘要：遷安市長(zhǎng)城金礦礦床屬于構(gòu)造蝕變巖型金礦床，賦存于薊縣系楊莊組（Jxy）白云巖及部分蝕變閃長(zhǎng)玢巖巖脈中，呈脈狀、似層狀產(chǎn)出，主要受斷裂或構(gòu)造破碎蝕變巖帶控制。隨著勘查與開(kāi)發(fā)的深入，人們對(duì)長(zhǎng)城金礦的認(rèn)識(shí)更加全面。本文結(jié)合長(zhǎng)城金礦的地質(zhì)特征，分析其找礦標(biāo)志，以更好地開(kāi)發(fā)金礦資源。

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.

Keywords： gold mine; geological characteristics; prospecting criteria; deposit; fracture; structural fracture zone; Qian’an City
