摘要
哈密市横山白云岩矿位于塔里木盆地北缘卡瓦布拉克—星星峡地块,经地质调查与综合研究,提交横山冶镁用白云岩矿推断资源量1.95亿吨(矿石量)。矿体的赋矿地层为蓟县系卡瓦布拉克群,赋矿岩性为浅灰色白云岩和白云石大理岩,矿体整体北倾,主要呈陡倾斜的层状,矿石质量好,内部夹石不连续,围岩为非矿白云岩、条带状灰岩,矿体后期受构造影响有少量脉岩穿插,经初步分析矿床成因为层控海相沉积变质型矿床。区域上该类型矿床严格受地层控制,主要呈近东西向—北东东向展布,具有较大的找矿潜力。成果的取得为哈密市持续布局壮大“镁基”产业提供了丰富的资源保障。
The Hengshan Dolomite Mine in Hami city is located in the Kawabulake Xingxingxia massif on the northern edge of the Tarim Basin.Through this geological survey and comprehensive research,a total of 195 million tons of dolomite ore resources for magnesium smelting have been submitted,reaching a large-scale.The ore-bearing strata of the ore body are the Kawabulake Group of the Jixian System,with light gray dolomite and dolomite marble as the ore bearing rock types.The ore body is generally inclined to the north,mainly in steeply dipping layers,with good ore quality and discontinuous interbedded rocks.The surrounding rocks are non mineral dolomite and banded limestone.In the later stage of the ore body,a small amount of vein rocks were interspersed due to structural influence.Preliminary analysis shows that the deposit is a layer controlled marine sedimentary metamorphic type deposit.This type of mineral deposit is strictly controlled by geological strata in the region,mainly distributed in a nearly east-west to northeast northeast direction,and has great potential for mineral exploration.The achievement of the results provides abundant resource guarantee for the continuous layout and growth of the“magnesium-based”industry in Hami city.
