Provenance Evolution of Age-Calibrated Strata Reveals When and How South China Block Collided With Gondwana by Yang, C., Li, X.H., Li, Zheng-Xiang, Zhu, M., Lu, K.

“…The South China Block (SCB) has been regarded by many as an integral part of Gondwana, but proposed timing and processes for its accretion to Gondwana vary and remain contentious, largely owing to the lack of reliable Pan-African age paleomagnetic data and tectono-magmatic records from the SCB. …”
