内蒙古苏尼特左旗扎拉格沃博勒卓铁矿地质特征与找矿标志
|
摘要
苏尼特左旗扎拉格沃博勒卓铁矿位于内蒙古中部,地处卡巴-红格尔庙铁成矿带,成矿地质条件优越。区内的铁矿主要赋存于蓟县纪温都尔庙群上部哈尔哈达组中,发育的温都尔庙式褐铁矿,属沉积变质型,是以往铁矿勘查的重点。该次勘查除发现上述类型铁矿外,在矿区及外围广泛分布的中元古代变辉长岩中,发育有具工业意义的磁铁矿体,矿床成因为岩浆熔离型。因此,今后在该地区进行铁矿勘查关注沉积变质型铁矿的同时,也应注意后期岩浆熔离型铁矿的寻找。
Zharagbolezhuo iron deposit in Sonid Left Banner is located in the central part of Inner Mongolia. It is located in Kaba-Honggelmiao iron metallogenic belt, and has favorable metallogenic geological conditions. The iron deposits in this area are mainly Haerhada formation in the upper part of Wenduermiao group of Jixian period. The Wenduermiao type limonite deposits developed in this area belong to sedimentary metamorphic type and are the focus of iron ore exploration in the past. In addition to the above-mentioned types of iron deposits, magnetite bodies of industrial significance develope in the Carboniferous metagabbros which are widely distributed in the mining area and the surrounding areas. The genesis of the deposit is magmatic dissociation type. Therefore, iron ore prospecting in the future in this area should be paid more attention to sedimentary metamorphic iron deposits and later magmatic melting iron deposits.
