摘要
Xiuyan area is one of the serpentine(Xiuyuan) jade producing areas in China.Marble of Dashiqiao formation in Liaohe group is the main horizon of Xiuyuan jade and the ore body of the jade is strictly controlled by ductile deformation-metamorphism belt and Proterozoic granite.In Xiuyan area occur not only serpentine jade but also tremolite jade.Ore body of the jade is in irregular vein or lens.Genetically,the jades in Xiuyuan area belong to hydrothermal alteration type.
