中国超高压变质岩十五年研究进展
Development of Studying Ultrahigh-Pressure Metamorphic
Rocks from China during the Past 15 Years
摘要
Abstract
Studies on the ultra-high pressure metamorphic (UHPM) rocks from China started in 1980s. Progresses so far made in the field could be summarized as follows.① The Dabieshan-Su-Lu UHPM belt has been well-known since many new outcrops of UHPM rocks were found;② Mineralogical evidences indicate that the continental crust rocks with low density could subduct down to depth of >200 km and undergo UHPM;③ UHPM rocks from the Dabieshan-Su-Lu area were dated as early Mesozoic when the Yangtze Craton subducted northward beneath the Sino-Korean Craton; ④ Fluids were not active and oxygen isotope composition of meteoric water could be preserved during UHPM process, as is evidenced by O, C, and H isotope data; ⑤Multistage models were suggested to explain the exhumation of the UHPM terrain. Some hotly debated issues were summarized.关键词
