摘要
滇西及缅北克钦邦、掸邦一带 ,属于欧亚板块与印巴板块碰撞带。该区存在的双变质带是闻名于世的宝玉石矿产地。此带以东即为高黎贡山变质岩带展布区及三江地区 :该区东部为高温低压变质带 ,西部为低温高压变质带 ,两者之间为过渡带。宝玉石矿床、矿点都受到岩性、断裂的控制。分析双变质带宝玉石矿床 (点 )的控矿因素、成矿规律及成矿机理 。
The region of west Yunnan and Kachin, Shan of north Myanmar belongs to the collision zone of eurasian plate and Indian plate. There are many famous gemstone-jade deposits in the bimetamorphic zone of it. East of this region, the Gaoligongshan metamorphic zone and three-river area consist of east high T-low P metamorphic zone, west low T-high Pmetamorphic zone and the transitional zone between them. And the gemstone-jade deposits are controlled by lithology and fracture. The analysis of control factors, mineralization rule and mechanism of gemstone-jade deposit in the bimetamorphic zone is the basis of searching for new deposit in the similar metamorphic zone.
