粤东莲花山地区花岗岩脉体锆石U-Pb定年数据集（2018-2019年）

以野外构造-沉积调查为基础，通过对粤东莲花山构造带的花岗质岩石锆石U-Pb定年，精确确定中生代华南构造变形序列，综合武夷构造带的资料，构建中生代华南构造体制转换的动力学模型，并确定古太平洋构造域的启动时间。本条数据对应于项目的考核指标2.3华南中生代构造体制转换过程模式。

Based on field structural and sedimentological surveys, this dataset is developed via zircon U-Pb dating of granitic rocks from the Lianhuashan Tectonic Belt in eastern Guangdong, to accurately ascertain the Mesozoic tectonic deformation sequence of South China. By integrating data from the Wuyi Tectonic Belt, a dynamic model for the tectonic regime transition of Mesozoic South China is constructed, and the initiation timing of the Paleo-Pacific Tectonic Domain is confirmed. This dataset corresponds to assessment indicator 2.3 of the project: Process Model of Mesozoic Tectonic Regime Transition in South China.
