摘 要: | 根据扫描电镜观察、X射线衍射和化学分析,研究断层泥中伊利石矿物的特征。研究表明,小湾断层泥中伊利石属I+ISII结构,膨胀层约占15%,IM多型,层间阳离子2Ca+Na+K≈1,伊利石的b。值等于8.993A,这些参数反映了小湾断层活动的机制为低压、低温(<200℃)。

CHAKACTERISTICS OF ILLITE MINERALS IN FAULT GOUGE FROM XIAOWAN,YUNNAN AND THEIR GEOLOGICAL SIGNFICANCE |
| |
Abstract: | In this paper,characteristics of illite in fault gouges are studied by SEM, XRD and chemicalanalysis.The study shows that illite belongs to I +ISIl structure;expansibility takes approxi-mately 15%; IMis of multiple paterns interlayer positive ions 2Ca+Na+K≈l;b_0 value of illite is8.993 in fault gouge at Xiaowan,which show that mechanisms of fault movement in Xiaowanare of low pressure and temperature(<200℃ |
