摘要
通过对东闯特大型金矿床的重点研究，综合前人资料，对小秦岭金矿田矿床成因提出了新的认识。成矿流体由地幔流体交代演化而来，成矿物质主要来自上地幔和下地壳，成矿时代为晚燕山期，不同形式的拆离构造为成矿流体提供了运移通道和富集空间，其成因类型为幔源中高温热液金矿床。
A new genesis of Dongchuang gold deposit in Xizoqinglin gold field is proposed. It is concluded that the ore-forming fluid comes from the evolution of metasomatism of the mantle fluid and the ore-forming material is mainly from the upper mantle and lower crust. The metallogenetic epoch is the later Yanshan period. Different shapes of detachment structure provides the transport channels and enriched spaces of ore-forming fluid. The deposit is a mantle-derived meso-hypothermal gold deposit.
