| 摘 要： | 从剪切带及原岩建造分析入手，论述了工作区内金矿的分布特征和主要控矿因素。区内的金矿床（点）无论其物质来源和时代如何，就其空间位置而言绝大多数金矿直接产在剪切变形变质带─—脆性及脆－韧性剪切带中。Ｆｅ／（Ｆｅ＋Ｍｇ）高比值的容矿岩石有利于金的沉淀富集。

| Abstract: | Based on the study of shear zone and protolith formation,this paper discussed the distri-bution feature and major ore-control factors of gold deposits in north Xixia County,HenanProvince. Almost all gold deposits or occurrences of this area occurred in shear deformation-metamorphism zone,that is brittle or brittle-ductile shear zone,no matter what the sourceof gold and the mineralization epoch is. The host rock of higher Fe/(Fe + Mg)ratio isfavourable to deposit of gold. |
