| 摘 要： | 朔里煤矿共生硬质高岭土矿赋存在下石盒子组底部的铝土泥岩中；其主要矿物为高岭石，次要矿物软水铝石，另有少量赤铁矿、金红石、锐钛矿等铁钛矿物；化学成分以Al2O3、SiO2为主，Fe2O3＋TiO2含量超过2％则不能圈定为矿体。朔里煤矿共生硬质高岭土矿共划分四种自然类型：①灰白-浅灰色高岭土矿，②深灰-灰黑色高岭土矿，③花斑状高岭土矿，④灰色含黄铁矿或少量鲕状菱铁矿高岭土矿。

| Abstract: | Hard kaolinite coexisting in the Suli coalmine is hosted in alumina mudstone at the bottom of the lower Shihezi Formation.The primary ore is kaolinite and the secondary boehmite with minor hematite,rutile,anatase and other ferrotitanium minerals.Chemical compositions are dominated by Al2O3 and SiO2.If the content of Fe2O3+TiO2 surpasses 2%,an ore body cannot be delimited.The hard kaolinite in the Suli coalmine is divided into four natural types:(1) grey-white to grayish kaolinite;(2) dark-grey to grey-black... |
