塔里木-中朝准地台北部内生磷矿成矿带研究

ON MINERALIZATION BELTS OF ENDOGENETIC PHOSPHATE DEPOSITS IN THE NORTHERN POSITION OF TALIMU AND SINO-KOREAN PAROPLATFORMS

塔里木一中朝两个准地台相关构造-岩浆带中,有两个巨大的超基性-碱性-碳酸岩杂岩型磷矿成矿带。塔里木准地台北缘巴楚-柯坪区、黑应山区、焉耆县胡拉沟区、赛列克布拉克-且干布拉克-阔克塔格区、团结村-北山区等是一个与碱性杂岩有关的磷、蛭石、铁、铌、钽、铍、锆石、稀土等系列矿种的成矿带。中朝准地台北部可划分出蒙中卓资-兴和区、阳原-怀来区、蓟县东部区、兴隆-青龙-绥中区、辽宁凤城-朝鲜朔州区等磷成矿远景区,其中阳原、怀来区中还可进一步确定出5个磷矿找矿靶区。

A tectno-magmatic province in relationship with the Dalimu and Sino-Korean paraplatforms defines two giant hyperalkaline to alkaline to carbonate mineralization belts. One belt, covering areas of Bachu-Keping, Heiyingshan, Hulagou of Yanchi county, Seliekebulake-Qieganbulake-Kuokedage, and Tuanjiecun-Beishan, is well-known as productive of phosphorus, vermiculite, iron, niobium, tantalum, beryllium, zircon and RE ores in association with alkaline complexes. The other, lies at the northern part of Sina-Korean paraplatform and stretching through districts of Zhuozi-Xinghe, Yangyang-Huailai, Eastern Jixian county, Xinglong-Qinglong-Suizhong and Fengcheng-Suzhou (Korea) may referred to as a prospective zone for phosphate mineralization. The Yangyuan-Huailae districts may be separated into five subdistricts as targets for phosphate-hunting.
