摘要
从矿石研究入手,文章论述了北祁连西段小沙龙铁矿床的矿石类型、组构、成分等特征。该铁矿石主要为泥钙质板岩型,包括磁铁矿矿石、菱铁矿矿石、赤铁矿磁铁矿矿石、黄铁矿化磁铁矿矿石、磁铁矿菱铁矿矿石等5种自然类型,金属矿物主要为磁铁矿、菱铁矿、赤铁矿,次为黄铁矿、褐铁矿,矿石全铁含量较低,磁铁矿颗粒较细,这些特点与火山沉积变质型铁矿床一致。
Based on the study on iron ore characteristics, the authors discussed iron ore types, ore fabric and chemical compo- nents in the Xiaoshalong iron deposit. The iron ore mainly is the mud - calcareous slate type, including magnetite iron ore, siderite ore, hematite - magnetite ore, pyrite - magnetite ore and magnetite - siderite ore. Main metal minerals are magnetite, siderite and hematite, minor pyrite and limonite. The iron ore has lower iron concentration and fine magnetite particles, which are similar to those iron ore of the volcanic sedimentary metamorphic iron depos,.＇t.
