| 中文摘要:中国内生金矿分布广，矿化产出层位多，矿床类型复杂。成矿物质主要来自四类含金地质建造。矿化与构造关系密切，与岩浆活动也有程度不同的联系。实际资料表明，燕山-喜马拉雅期是中国内生金矿的主要成矿期。中新生代中国大陆所处的特殊板块运动环境所导致的构造-岩浆事件及随之出现的前所未有的热效应和扩容空间效应，是中国内生金矿集中形成于这一时期的根本原因。本文最后对中国内生金矿成矿的演化过程作了归纳。 |

| Abstract:Endogenic gold deposits of China are characterized by wide distribution, multiple mineralized beds and complex ore deposit types. Ore-forming substances are derived mainly from four types of auriferous geological formations, namely, Archeozoic metamorphosed intermediate-basic volcanic formation (greenstone belt), ultrabasic-basic volcanic formation, turbidite (flysch) formation and Mesozoic-Cenozoic intermediate-acid volcanic-subvolcanic formation. Mineralizations are closely related to structures and also have something to do with magmatic activities. The data available show that the Yanshanian-Himalayan period is the major metallogenic period for endogenic gold deposits in China. The tectonic-magmatic event caused by specific plate movement environment in which Mesozoic-Cenozoic Chinese continent lay and the unprecendented heat effect as well as the dilation space effect seem to be the fundamental reason why endogenic gold deposits in China are concentrated in this period. Finally, this paper summarizes the ore-forming evolutionary process of endogenic gold deposits in China. |
