福州峨嵋铝绿泥石叶蜡石型矿石

A New Type of Ore in Emei Pyrophyllite Deposit,Fuzhou Sudoite-Pyrophyllite Ore

借助于ｘ光粉晶衍射、差热、红外光谱、化学分析等方法对福州峨嵋叶蜡石矿中的纯叶蜡石型和高岭石型叶蜡石矿石进行研究，表明它们大部分是属于铝绿泥石─叶蜡石组合的矿石。矿物组合简单，化学成分较特殊，与纯叶蜡石型、高岭石型有明显的区别。

Studies on pure-pyrophyllite ore and kaolinite-pyrophyllite ore,in Emei pyrophyllite deposit,Fuzhou, have been carried out using XRD, DTA, IR and chemical analysis.The studics show that most of them consist of sudoite and pyrophylllite and have the compositions with higher Al2O3 and lower SiO2.They are different from the so-called pure-pyrophyllilte and kaolinite-pyrophylite ore in their mineral association and chemical composition, and are, therefore,found to be a new type of ore in the deposit.
