遂安石晶系归属探讨

STUDY OF CRYSTAL SYSTEM ASSIGNMENT ON SUANITE

遂安石是一种硼酸盐矿物 ,它的晶系归属一直是争论的问题。通过对辽吉硼矿床的遂安石的双晶观察、X射线衍射分析和电子衍射分析 ,结果表明它应是三斜晶系 ,β=10 4 .5°。

Suanite is a borate mineral. Its crystal system assignment has been not determined by now. The evidences of the twin observation, X ray diffraction analysis and electron diffraction analysis shown that the suanite belongs to triclinic system with β =104.5°.
