山东蓬莱地区金矿成矿背景与成矿规律探讨

Reserach on Geological Condition of Ore-forming and Metallogenic Regularity in Penglai City of Shandong Province

摘要:

在系统分析蓬莱地区各矿山已有地质资料及近年来该区金成矿理论研究的基础上，对蓬莱地区区域地质背景进行了分析，认为蓬莱地区金成矿为一系列构造、岩浆活动叠加，中生代集中成矿的结果。蚀变、矿化分带与构造分带协调对应，呈现三位一体；矿床空间分布具有一定规律性，断裂构造拐弯或交会部位赋矿，构造倾角变化部位赋矿，矿体尖灭再现、分枝复合规律，矿体侧伏规律；各种类型金矿床在时空分布和成因上密切相关，由于控矿条件和成矿环境的异同，形成不同类型矿床和同种类型矿床的组合。

Abstract:

Combining with exploration and based on geological data of mines and theoretical research on gold mineralization in recent years in Penglai area, alteration and mineralization regularity, characteristics of gold enrichment, spatial distribution pattern of gold deposits and deposit types distribution regularity have been summarized. It will provide the basis and direction for further gold exploration work.
