| 中文摘要: |
| 岫岩是我国主要蛇纹石玉产地,辽河群大石桥组大理岩层是岫岩玉石矿最重要的蕴矿层位,矿体严格受地层中韧性变形变质构造带和元古宙花岗岩的控制。在岫岩不仅产有蛇纹石岫玉,还产出透闪石岫玉。矿体形态呈不规则脉状及透镜状产出。岫岩地区的岫玉矿床成因应属于热液交代蚀变矿床类型。 |
| 英文摘要: |
| 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. |
