摘　　要：分析了河南省南召县石林沟地区铁多金属矿床的地质特征及成因.矿床矿体呈层状、似层状,与围岩产状一致.矿石结构有半自形晶粒状结构和他形粒状结构,另有少量残余结构、镶嵌结构等;构造主要有块状构造、条带状构造、浸染状构造等.初步认为该矿床是沉积变质热液改造型铁等多金属矿床.The geological features and genesis of the iron polymetallic deposits at Shilingou ditch,Nanzhao County,Henan Province are analyzed.It is clarified that the deposit body possesses a lamellar or pseudo-lamellar structure,in analog to those of the peripheral rocks;and the ore itself is both semi-diomorphic and alltriomorphic,with a small amount of residual structures embedded within it.The geological structure of the deposit is massive,banded or disseminated.A preliminary analysis concerning the genesis of the deposit shows that it is a sedimentary,metamorphic and hydrothermal iron-polymetallic ore deposit.
