【摘要】 高压—超高压变质岩石在大别山地区广泛分布。本文在概略介绍其产出地质背景,岩石及矿物标志的基础上,根据大别山地区的降升剥蚀量,并利用热力学原理对其形成深度,压力(高压釜机制)进行了推算,对其形成机制与折返过程作了新的探索。更多还原

【Abstract】 It is widely contributed of the High Ultra-high Pressure Metamorphic rocks in Dabie Mountains. It is described on the geological setting, the marks of the petrology and mineralogy of the UHP Metamorphic rocks. According to the estimate of the uplifting and erosion of the Dabie Mountains, and thermodynamics theory, it was evaluated the depth and pressure (high pressure autoclave) of the formed setting of the UHP Metamorphic rocks. Based on all mentioned above, there is a new explanation on the mechanism of formed and the processes of return of the UHP Metamorphic rocks. Keywords: blue schist belt, eclogite bearing coesite belt, "abnormal crustal pressure", "autoclave of high pressure更多还原
