大别造山带中生代陆缘向陆内变形的演变及其动力学

Key Points

• The central aim is to understand the historical transformation of Mesozoic deformation from continental edge collision to inland in the Dabie orogenic belt.
• Analyzed regional tectonic evolution focusing on the Dabie orogenic belt.
• Investigated the closure of the Paleotethys Ocean and subsequent metamorphic processes.
• Examined structural and rock unit formation during subduction and exhumation.
• Dabie orogenic belt records complete history of tectonic evolution from ~266 Ma.
• High-pressure and ultra-high-pressure metamorphism observed during southward subduction of the South China plate.
• Transitional phases observed from continental edge collision to inland deformation in the early Jurassic.
