甘肃金塔县穿山驯铅矿地质特征及找矿标志
|
摘要
穿山驯铅矿区域上位于塔里木板块、北山中—南带加里东期褶皱带、柳园—旧寺墩前陆基底,北邻北山南带(红柳园—大奇山—野马井)华力西裂谷,南与塔里木地台、敦煌地块相接。矿体产于华力西晚期第三次侵入的花岗闪长岩体与长城系古硐井群第二岩组白云石大理岩的外接触带附近。呈透镜状状、层状、细脉状赋存在白色厚层状白云石大理岩中。围岩蚀变主要有透闪石化、透辉石化、硅化、石棉化、萤石化、重晶石化、石膏化、黄铁矿化、褐铁矿化、孔雀石化等。长城系古硐井群第二岩组白色厚层状白云石大理岩是矿床的直接找矿标志,透闪石化、透辉石化、硅化、石棉化、萤石化、重晶石化、石膏化、黄铁矿化、褐铁矿化、孔雀石化等围岩蚀变是矿床的间接找矿标志。
The Chuanshantao lead deposit is located in the Tarim plate, the Caledonian fold belt in the middle-south zone of Beishan, the Liuyuan-Jiusidun foreland basement, the Hualixi Rift Valley in the South Zone of Beishan(HongliuyuanDaqishan-Yemajing), and the Tarim platform and Dunhuang block in the south. The orebody occurs near the outer contact zone between the third intrusive granodiorite body of late Variscan and the dolomite marble of the second formation of Gudongjing Group of Great Wall System. Lens, layers and veins occur in white thick-layered dolomite marble. Surrounding rock alteration mainly includes tremolite, diopside, silicification, asbestos, fluoride, barite, gypsum, pyritization, limonite,malachite and so on. White thick-bedded dolomite marble of the second formation of Gudongjing Group in Great Wall System is the direct prospecting indicator of the deposit, and wall rock alteration such as tremolite, diopside, silicification,asbestos, fluorite, barite, gypsum, pyritization, limonization and Malachite are indirect prospecting indicators of the deposit.
