山东省栖霞市金山矿区金矿床地质特征及成因研究

Geological characteristics and genesis of gold deposits in Jinshan mining area,Qixia City,Shandong Province

山东省栖霞市金山地区金矿位于东金成矿区中部、蓬莱—栖霞成矿带南段的栖霞金矿田内,矿床成因类型为受韧—脆性构造控制的深源中低温热液充填石英脉型金矿床,具体成矿期分别为新太古代末期—元古代末期、中生代与新生代,其成矿热液主要来自中生代区域构造—岩浆热事件,次为元古代韧性剪切构造—变质热液。

The gold deposits in Jinshan area,Qixia City,Shandong Province are located in the Qixia gold field,which is located in the middle of the East gold metallogenic area and the south part of Penglai Qixia metallogenic belt.The genesis of the gold deposits is controlled by the ductile brittle structure.The specific metallogenic periods are from the late Neoarchean to the late Proterozoic,Mesozoic and Cenozoic.The metallogenic hydrothermal fluid is mainly from the middle The regional tectonic magmatic thermal event in the Cenozoic era was followed by Proterozoic ductile shear structure metamorphic hydrothermal.
