Phanerozoic metamorphism and crustal evolution in the southeastern part of China

摘要: Abstract From the point of view metamorphic cycle, crustal evolution during Phanerozoic in southeastern part China can be divided into two cycles, i.e. Palaeozoic cycle (600-190 Ma) and Mesozoic-Cenozoic (190-10 Ma), which separately reflect different features heat flow geological environment. The from Caledonian to Variscan-Indonisian epoch, metamorphism is characterized by low pressure type regional dynamic thermal polymetamorphism, while greenschist facies temperature monometamorphism, reflecrs changes higher lower environment active stable. During Mesozoic-Cenozoic, affected movement Pacific Plate, Yanshanian led formation Changle-Nan'ao Lianhuashan belts series, Danan'ao belt mostly glaucophane facies. They must have occurred as paired formed time. Eastern Taiwan burial Western low-temperature were Himalayan event Cenozoic.
