甘肃北山地区拾金坡式岩浆热液型金矿成矿模式建立

摘要

通过对拾金坡金矿的区域地质背景和成矿地质环境（含矿地层、控矿构造、侵入岩、矿质来源、含矿热液运移方式及矿体赋存形态等）分析认为：拾金坡金矿床矿质主要来源于拾金坡复式岩体,受断层构造控制,后期构造活动及热液扰动促使了成矿作用的发生。本文总结归纳了主要成矿要素,揭示了典型矿床的成矿规律,并尝试性的建立了拾金坡式岩浆热液型金矿成矿模式,以期指导拾金坡—金场沟侵入岩区金成矿带的矿产勘查与研究。%Through analyzing the background of regional geology and the geo-environments of metallogeny in Shijinpo gold deposit（ore bearing bed,ore-controlled structure,intrusive rocks,source of ore-forming substances,migration of ore bearing hydrothermal solution and emplacement occurrence of ore body）,the paper summarized the main metallogenic factors,expounded the metallogenic regularities of typical deposit,and established the metallogenic model of Shijinpo magmatic-hydrothermal-type gold deposit.
