| Abstract: | A rhodonite deposit has been discovered and evaluated for the first time in Shaanxi Province.The rhodonite occurs in manganiferous rocks, manganiferous quartz-dolomite marble and quartzite,which are intacalated in the lower part of the middle member in the Sichagou Formation of the lower Proterozoic Kuanping Group.Though the orebodies are distributed in bedding,they are relatively conglomerated.The rhodonite deposit was for- med mainly through two stages,sedimentation and regional metamorphism, and its genetic type belongs to epithermal metamorphic facies. |
