摘    要：河南洛宁蒿坪沟－铁炉坪地区内银金多金属矿床以脉状矿床为主,明显受断裂构造控制,其形成与地壳伸展造山及变质核杂岩构造密切有关,变质核内的太华群地层是矿源层;伴随变质核隆起的花岗岩侵入活动,一方面提供部分成矿物质,另一方面促进成矿物质的活化转移;拆离断层的形成与活动,为矿液的运移和富集提供了有利的空间.

Abstract: The silver－gold polymetallic deposits in the Haopinggou－Tieluping mainly belong to veindeposit and are evidently controlled by the fracture structure,The formation of the depositsis closely related to the crystal extensional orogenesis and the metamorphic core complexstructure.The Taihua Group has been considered to be the ore－original stratum. The intru-sion of the granites accompanied by the uplift of the metamorphic core provides part of theore·forming material on the one hand and promotes the activation and movement of ore-form－ing material on the other hand. The formation and action of the detachment fault provide thespace for the movement and concentration of the ore－forming material.
