Early Paleozoic intracontinental orogeny and post-orogenic extension in the South China Block: Insights from volcanic rocks

The early Paleozoic orogeny represents the first extensive Phanerozoic tectono-thermal event in the South China Block (SCB). Two distinct orogeny models, subduction–collision orogeny and intracontinental orogeny, have been proposed, and one of the key controversies is the nature and the tectonic implications of the associated early Paleozoic volcanic rocks in the SCB, which have not yet been systematically investigated.
