摘要
研究了中国北方石炭系高岭石夹矸的矿物组成和化学成分：主要矿物是高岭石，占９０％以上，化学成分近似于高岭石的理论成分；分析了该层夹矸在不同温度煅烧后的矿物相变化特征；得出了北方石炭系高岭石夹矸是优质高岭石矿产资源，是生产铝盐和Ａ型分子筛的优质无机化工原料的结论．
The main mineral of Carboniferous series tonstein in North China is kaolinite (above 90%). The chemical composition of the tonstein is similar to that of kaolinite. Its structural changes at different temperatures are studied by X -ray diffraction. It is concluded that the tonstein is a high-grade kaolinite mineral resource and is capable of producing aluminium salts and A-model molecular sieve.
