【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 ,为在滇西相似的双变质带中进一步寻找宝玉石矿藏提供依据更多还原

【Abstract】 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.更多还原
