The study indicates that the chemical cemposition types of various typomorphic minerals are as follows: picotite CrOa-a(c)3aa>53%, Ala-a(c)2aaOa-a(c)3aa£1/411%,MgO£1/412%, the value of Craa(c)#aa is above 0a±7, pyrope Cra-a(c)2aaOa-a(c)3>5%, Al_a(c)2aaOa-a(c)3aa<19%, t.
研究得出,各矿物指示含矿的化学成分标型为:铬尖晶石Cr2O3>53%,Al2O3<11%,MgO<12%,Cr#值大于0 7。
The lacunary picotite was found in the 1950′s and over a long period of time it had been mistaken for the magnetite because of its high reflectivity and magnetism.
