已知辉钼矿有两种多形体:六方的(2H)与三方的(3R);由于测定辉钼矿多形体的方法尚未齐全,因而辉钼矿新的结构形体所呈现的特点实际上还未予以研究。利用 X射线研究方法(Deane 等,1970)鉴定辉钼矿的多形体是最能令人信服的。本文提出直接在光片中并不破坏颗粒以反射光的色散曲线鉴定辉钼矿多形体的方 It is known that there are two polymorphs of molybdenite: hexagonal (2H) and tripartite (3R); the characteristics exhibited by the new structural form of molybdenite are actually also due to the incomplete method for the determination of molybdenite polymorphs Not studied. The identification of polymorphs of molybdenite using X-ray studies (Deane et al., 1970) is most convincing. In this paper, we propose a method for the identification of polymorphs of molybdenite directly in the light film without destroying the particles to reflect the dispersion curve of the light
