摘要
以地质作用为表现形式的成矿能量释放方式和成矿地质-地球化学环境为依据,将金矿床分为5种主要类型;并针对我国金矿成因的复杂性和有关过渡性地质作用及多期多阶段的成矿特点;提出了以含金建造为基础的金矿端员类型、过渡类型和叠加类型的划分方案。这种新的分类设想不但可以对金矿成矿类型的现有认识加以总结和分类,同时也考虑到今后该项研究的深入发展,为可能发现的金矿新类型提供合理的分类位置。
Five major types of gold deposits are classified according to theenergy-releasing way expressed as a certain geological process bywhich the ore deposit was generated and their geological and geochemi-cal environment; and in accordance with the gold deposits in China, someof them showing transitional ore-forming environments or multiplesuperimposed geneses, a concept of end-member, transitional andsuperimposed types about the classification system of gold deposits layingthe material base of the gold-bearing formation is suggested. This newidea not only summarizes and classifies known types of the deposit, butalso provides suitable sites in classification for potentially discoverednew types of gold deposit considering the future development of thisfield.
