polytype

基本解释

On the basis of relative diffraction strength, the criterion for differentiating polytype 1Tr from 2M wollastonite is provided.
初期以多型转变为主,后期以晶体结构破坏为主,晶格畸变效应贯穿变化的全过程。
Their crystallinity is very high and their polytype is 2M_1.Both of them are dioctahedral because the d_(060) and b of micro-crystal muscovite and phengite are 0.1502 nm,0.9012 nm and 0.1505 nm,0.9030 nm,respectively.
二者都属二八面体型白云母类矿物;但d060和b值偏大;微晶白云母的d060=0.;1502 nm;b=0
