Provenance of Middle Triassic sediments in the Southern Youjiang Basin: Insights from detrital zircon geochronology and tourmaline geochemistry
The sedimentary provenance and tectonic setting of the Youjiang Basin in southwestern China remain debated, particularly regarding the relative contributions of the Indochina Block and the southeastern margin of the South China Block (SCB) during the Indosinian Orogeny. This study integrates detrital zircon U–Pb geochr...
