| Abstract: | In Nov.1992,the auther found a mineral in North Shaanxi province in thesalt-bearing sequence of the Odovician Majiagou formation to be associated with thehalite seams.Microprobe analysis gave the mineral chemical compositions of52.02% K and 47.73% C1,with a measured refractive index 1.4903.In addition,analyses of X-ray diffraction,optical microscope and so on were made for itsidentification.All this reseasonably refered this mineral species to sylvite.Furtherresearches on it included petrological and mineralogical. |
