位于扬子陆块西缘的石棉草科穹状变形变质体，据近年来的研究表明，该穹隆体经历了三次变形变质时期：早期为收缩滑脱变形的区域动力变质、中期热隆伸展动热变质和后期岩浆热接触变质。对主期变质划分出黑云母带、石榴石带、红柱石－十字石带和矽线石带，确定为低压相系，利用变质反应、矿物地质温压计及相关的同位素年龄资料，建立了草科穹状变形变质体演化的ｐ－Ｔ－ｔ－Ｄ轨迹。轨迹图呈顺时针形式，具碰撞造山带环境的特点，变形变质过程受变质体前缘西油房韧性剪切带逆冲－推覆作用和后缘碰撞晚期岩浆大规模上侵的双重制约，为深源岩浆热动力变质成因，属穹状岩浆核杂岩构造。
According to the recent studies, the dome has undergone three stages of metamorphism and metamorphism: regional dynamic metamorphism during the early stage of shrink-slip deformation, mid-term extension of the thermo-hydro stretching thermal metamorphism And late magmatic thermal deterioration. For the main metamorphism, the biotite belt, garnet belt, andalusite-lithic belt and sillimanite belt were identified as low-pressure facies series. Based on the metamorphic reaction, mineralogy geothermometer and related isotopic age data, The p-T-t-D trajectory of the evolution of dome-shaped dome deformities. The trajectory is clockwise with the characteristics of collisional orogenic belt environment. The deformation and metamorphism process is controlled by the thrust-thrusting of the ductile shear zone in west oil chamber at the front of the metamorphic body and the large-scale intrusion of magmatic late late collision. For the deep source of thermal power metamorphism, is a dome-shaped magmatic core complex structure.
