神农架铁矿位于华中第一高峰——鄂西神农架原始林区。目前发现具有工业价值的矿区主要有两个:一个在铁厂河,另一个在大神农架主峰附近(图1)。铁矿露头一般在标高2000—2500米以上。虽然该铁矿沉积形成于元古代,但由于它至今几乎未受变质,使它具有独特的矿石类型,以区别于一般前寒武纪沉积变质铁矿,因此人们专称它为神农架式。现将该铁矿特征简要报道如下。
Shennongjia iron ore is located in the first peak in central China - Hubei Shennongjia virgin forest. There are currently two major mining sites of industrial value: one at the Ironworks River and the other near the main peak of the Shennongjia (Figure 1). Iron outcrops are generally above the elevation of 2000-2500 meters. Although this iron deposit was formed during the Proterozoic, it has been called Shennongjia because it has little to no metamorphism so far that it has a unique ore type that distinguishes it from the general Precambrian sedimentary iron ore. The characteristics of this iron ore are briefly reported below.
