This is a complex collision tectonics region of Precenoozic terranes, which can be divided into several elements from west to east, as follows: northwest Fujian terrane, Longquan collision zone, southeast Zheijiang、terrane, costal collision zone and Wen Don terrane.
The Moho that underthrusts beneath the Dabie orogen and the south-dipping reflections of southern Dabie create a crossed reflection image, depicting the collisional structure beneath the collision of the Yangtze foreland and Dabie orogen.
By means of geochemical and geobarometric methods, it is estimated that the depth of emplacement for Jinjiling batholith was about 6.5km, and the rock forming pressure was about 180MPa. Jinjiling composite granitic batholith belongs to S type granitoids, forming in collision orogeny environment.
Regional metamorphism related to collision tectonics in the Late Carboniferous (Hercynian) and later during the Alpine orogeny, caused intensive recrystallization and partial mobilization of the various carbonate phases.
The mineralising event is interpreted as relating to input of deep-sourced fluids during late-orogenic exhumation at the transitional stage between collision tectonics and the late-Variscan extensional regime.
The collision tectonics of the southern Greek Neotethys
Eastern European alpine system and the Carpathian Orocline as an example of collision tectonics.
They are useful information for understanding the collision tectonics of the Taiwan Island.
