摘要
通过对龙溪软玉中矿物纤维所进行的电子衍射研究,发现了透闪石针状晶体中存在众多(010)多链层错,透闪石和滑石以(010)为晶界面形成连生,以及滑石晶体呈纤维状存在;探讨了透闪石退变质为滑石的反应运动学和反应动力学机制;提出了拓扑定向反应系列的理论。
An electron diffraction study of mineral fibres in Longxi nephrite wascarried out mainly under an H-800 electron microscope, revealing that a lot of(010) multiple-chain faults are developed in acicular crystals of tremolite, tre-molite and talc are intergrowing with (010) as the interface, and talc crystalsoccur in the form of fibres. Thus, the kinematic and kinetic mechanisms fortremolite-talc retrogressive reaction were explored and a theory of topotacticreaction sequence has been proposed.
