| 摘 要： | 俯冲带中流体与岩石相互作用以及流体循环一直是地质学家关注的焦点之一.硬玉岩(翡翠)作为高档宝玉石材料,其成因一直备受关注.硬玉岩产于与俯冲带有关的蛇纹石化超镁铁质岩中,是俯冲带中流体与超镁铁岩相互作用的特殊产物.岩石组合、岩相学、显微结构及矿物化学特征表明:橄榄岩与流体的作用可以分为5个阶段,分别为蛇纹石化→(绿泥石、...

| Abstract: | The fluid-rock interactions and fluid circulations in subduction zone have been a focus for geologists.As a kind of high-grade gem material,the genesis of jadeite rocks attracts an increasing concern.The jadeite rocks generally occur in the serpentinized ultramafic rocks in subduction zones and its formation is related to the interaction between subduction-related fluids and ultramafic rocks(peridotite).Based on rock association,petrography,microstructure and mineral chemical characteristics,the processes o... |
