摘要
滑间皂石产于二叠系茅口组下部的黑滑石矿中。共生矿物为滑石、方解石、石英和炭质。滑间皂石具有强的23—24(?)(001)及11—12(?)(002)的 X 射线衍射峰,Mg-甘油饱和后,(001)的反射膨胀至26—27(?),d(060)值为1.526—1.527(?)。滑间皂石的电子显微象与蒙皂石类似,红外吸收光谱及差热曲线兼具滑石及皂石的特征。本次发现的滑间皂石有序度较差。
Aliettite occurs in the black-talc deposit in the lower part of the Permian Maokou Formation.Its associated minerals are talc,calcite,quartz and carbonaceous substance. Aliettite has intence XRD peaks of 23-24 (?)(001)and 11-12 (?)(002),and the reflection of (001)expands to 26-27 (?) when it is Mg-glycerine saturated.The value of d(060)is 1.526- 1.527(?).Electron micrograph of aliettite is similar to that of smectite.Infrared adsorption spectra and thermodifferential cures of aliettite are characteristic of both talc and sapohite. Degtees of order of aliettite discovered this time are not good.
