伊德萨斯山铁矿是一个含钛磁铁矿床.它在阿拉伯地盾的东缘形成一个狭长的弧形带.块状富矿(平均含铁63%)赋存于若干透镜状矿体群、板状矿体和矿脉中,并伴有浸染状细脉及扁豆状矿体.第三种类型是由磁铁矿和闪石(阳起石-透闪石)组成的伟晶状矿石.次生镜铁赤铁矿见于充填裂隙内.矿体产于艾马尔伊德萨斯断层以东的辉长岩(辉长苏长岩和变质苏长岩)和变质安山岩(属哈尔班群)内,矿体普遍受到强烈的构造变动,局部被安山岩和微闪长岩岩脉切穿.岩体的走向在该带的北部为北北西-南南东,在
The Idesasan Iron Ore is a titaniferous magnetite deposit that forms a long, narrow arc zone on the eastern edge of the Arabian Shield. Massive bonanza (63% of the average iron content) occurs in a number of lenticular oreblocks, Plate-shaped orebodies and veins, with disseminated veinlets and lentil ore bodies, and the third type is a great crystalline ore consisting of magnetite and amphibole (lithocite-tremolite). The birchite hematite is found in the filling fissures.The orebodies are produced in the gabbro (gabbroic and metamorphic) and metamorphosed andesite (belonging to the Khabarba complex) to the east of the El-Imadis fault, Generally subjected to intense tectonic movements and is locally cut by andesite and diorite dikes.The strike of the rock mass is north-northwest-south-south east of the belt,
