Mesozoic tectonic regime and evolution of eastern China: A mini-review based on the recent development

Eastern China experienced multiple tectonothermal events during the Mesozoic. Especially, vast extensional structures was dominated in the late Mesozoic. The geological evolution characterized by large-scale metamorphic core complexes, ductile detachments, and domes is traditionally referred to as the Yanshanian (period) cycle. According to our study, the South China Block (SCB) can be characterized by a general lithospheric extension, as the same as the North China Carton (NCC) and its adjacent regions. Accompanying with Yanshan movement, a variety of intrusions and deposits were formed associated with mantle-derived magmatism. We propose a metallogenic model to better describe the ore genesis of the Au-polymetallic deposit in the Jiangnan Orogen Belt. Furthermore, mechanochemical mechanism has been applied to research the substantial relationship between mineralization and structure. It is a new sight to study the regularity of the constraint on the genesis of shear zone related deposits. We briefly introduce the recent achievements in the regional tectonic regime and its evolution effect on mineralization in eastern China. To further investigate this problem, more work should be undertaken by researchers from both structure and mineralization fields. Copyright (C) 2019, Guangzhou Institute of Geochemistry.
