(一)概况 邯邢铁矿产于中奥陶统马家沟组灰岩与燕山期偏中性杂岩接触带中,属接触交代～热液充填型磁铁矿床。 主要矿物为磁铁矿、黄铁矿,其次为假像赤铁矿、褐铁矿、黄铜矿;主要脉石矿物有透辉石、石榴石,其次为阳起石、透闪石、金云母、绿泥石、蛇纹石、方解石等。 磁铁矿占矿物总量的一半以上,黄铁矿为本地区的主要硫化矿物。磁铁矿呈半自形、它形晶结构,粒径0.1～0.5毫米;黄铁矿多呈半自形粒状和各种溶蚀交代结构,粒径0.1～0.8毫米。钴以类质同像形式较均匀分布于黄铁矿中,增加了黄铁矿的经济价值。 (I) Overview Handan iron ore production in the Middle Ordovician Majiagou limestone and Yanshanian period of the middle of the contact zone, is a contact metasomatism ~ hydrothermal filling type magnetite deposit. The main minerals are magnetite, pyrite, followed by fake hematite, limonite, chalcopyrite; the main gangue minerals are diopside, garnet, followed by Yang stone, tremolite, gold Mica, chlorite, serpentine, calcite and so on. Magnetite accounts for more than half of the total minerals, pyrite is the main sulfide minerals in the region. Magnetite is semi-self-shaped, its crystal structure, size 0.1 ~ 0.5 mm; pyrite mostly semicircular shape and a variety of dissolution corrosion structure, size 0.1 ~ 0.8 mm. Cobalt is homogeneously distributed in pyrite in the form of isomorphism, increasing the economic value of pyrite.
