摘要
巴东县刘家湾铁矿属鄂西宁乡式铁矿,含矿层位为泥盆系上统黄家磴组(D3h)和写经寺组(D3x),其中写经寺组上段(D3x2)底部为主要矿层。对矿层地质特征及矿石组构进行了对比分析,对铁矿的成矿环境、铁质来源、成矿机制进行了讨论,指出该矿床沉积于滨海—浅海相古地理环境。
The Liujiawan iron deposit in Badong county belongs to the Ningxiang-type iron deposit in western Hubei. It occurs in the transitional horizon in Huangjiadeng formation （ D3 h ） and Xiejingsi formation （ D3 x） of the upper devonian system,especially the bottom of the upper Xiejingsi formation（D3x2）. The article analyzes the seam＇s geological charac- teristics and the ore fabrics, discusses the metallogenic environment, the source and minerogenetic mechanism for the iron ore, points out that the ore deposit sedimentates on the palaeogeographic environment of littoral-shallow seafacies.
