摘　　要：黑石河铁矿位于攀西地区,其含矿岩体以辉长岩体为主,岩体具弱分异并显示一定的层理构造;矿体呈似层状、透镜状、脉状产。通过对矿石特征研究,认为矿石主要以海绵陨铁结构及浸染状构造为主,矿物组成主要有钛磁铁矿、钛铁矿等金属氧化物、以黄铁矿为主的硫化物,以及辉石等组成。基于矿区主要矿物的结晶阶段及黑石河铁矿石典型的结构构造特征,结合攀西地区其它钒钛磁铁矿床成因研究资料,认为黑石河铁矿床属岩浆晚期分异结晶成因类型。The Heishihe iron deposit is located in Panxi region. Gabbro is the key ore-bearing body weak differentiation and bedding. The ore body is layeroid, lenticular and veinlike. Study on the ore character- istics shows mainly sponge iron metyeorite texlure and dissemination structure. The lore is composed of Ti-magnetite, ilmenite and metal oxides, sulfides （mainly pyrite）, pyroxene etc. The Ti magnetite, il- menite and metal oxides are the ore minerals. Combined with discussion of the ore genesis in other vanadi- um-titanium magnetite ore that is located in Panxi region and also based on the main mineral crystallization stage and the typical texture and in Heishihe iron ore, the deposit is a late magma fractional crystallized deposit.
