文摘
- •
Arc-related magmatism in Central Tianshan occurred in 450–420 Ma and ceased at 417–400 Ma.
- •
Top-to-the-north ductile shearing deformed the early Paleozoic arc-type intrusions.
- •
Mid-late Paleozoic intrusions were free from regional N–S compressive ductile deformation.
- •
Early Carboniferous amalgamation of the Central Tianshan and Tarim is proposed.
- •
Paleozoic intrusive rocks were locally mylonitized due to Permian transcurrent tectonics.
