朝鲜朔州碱性杂岩体蛭石-磷灰石矿床是塔里木-中朝准地台北缘最早发现并勘探的典型偏碱性超基性岩-碱性岩-碳酸岩三位一体的碱性杂岩体蛭石-磷灰石矿床,其后的20年里我国陆续发现矾山、且干布拉克、马伸桥三个典型碱性杂岩体磷矿,表明塔里木-中朝准地台北缘具有良好的碱性杂岩型磷矿成矿地质构造条件,是具有重要成矿远景的成矿带.朔州杂岩体为印支期侵位于太古宇黑云母花岗岩、片麻岩中,大地构造位置属于营口-宽甸-狼林隆起.岩体由三个侵入期岩石组成,第一期侵入岩为偏碱性超基性岩,第二期为碱性岩,第三期为碳酸岩,磷灰石矿体按成因类型分为碳酸岩型、碱性岩型和交代型,磷矿与碳酸岩和碱性岩有关,蛭石矿与超基性岩有关,磷矿探明储量1亿t,远景储量数亿t,为大型蛭石--磷矿床.

It is a typical ternary basic complex rock vermiculite- apatite deposit of light alkaline ultrabasic rock-alkali rock-carbonatite, which was discovered at soonest and prospected at north edge of Tarim-Sino Korean paraplatform. The three typical basiccomplex rock phosphorite of Fanshan, Qiebulake, Mashenqiao which were discovered in later 20 years, all of which show that the north edge of Tarim-Sino Korean paraplatform have the better geological structure condition for forming basic phosphorite. Be invaded in the archaean biotite granite and gneiss in Indo-Chinese epoch, the geotectonic location of Shuozhou countycomplex rock belongs to Yingkou-Kuandian-Langlin doming. Three intrusive rocks including light alkaline ultrabasic rock and alkali rock as well as the carbonatite formed the rock body. There are three types apatite body of carbonatite, alkali rock and metasomatic type. The phosphorite is developing with carbonatite and alkali rock as well as the vermiculite is developing with ultrabasic rock. It is a large scale vermiculite- phosphorite deposit with the demonstrated reserves of a hundred million phosphorite and future reserves of somenumber hundred million phosphorite.
