河南省安林式铁矿地质特征及成矿规律——以安阳县李珍铁矿为例

The Geological Characteristics and Metallogenic Regularity of Anlin Iron Deposit in He'nan Province——The Case of Lizhen Iron Deposit,Anyang County

河南省安林式铁矿主要以矽卡岩(接触交代)型铁矿为主,接触交代型铁矿主要产在中酸性—中基性侵入岩类与含钙镁质碳酸盐类岩石的接触带或其附近,分布范围大,层位稳定,成矿条件好,其特点是小而富,有着良好的找矿前景。从该类型铁矿的地质特征及成矿规律着手,探讨了铁矿的富集规律,为今后找矿与勘探提供理论依据。

Anlin iron mine are mainly skarn（contact metasomatic） iron ore,which is produced in the contact zone of acidic-intermediate mafic intrusive rocks and calcium magnesian carbonate rocks.It has large area,stable layer and good ore forming conditions.So it has good prospecting potential.The author attempts to look for iron ore enrichment regularity from its geological characteristics and metallogenic regularity to provide theoretical basis for future prospecting and exploration.
