Implications for provenance and tectonic setting of the Middle–Late Mesozoic clastic sedimentary rocks in the Nanling Region, South China

The South China Block (SCB) hosts numerous economically significant granite-related uranium deposits and critical metal mineralization, notably in the Nanling Region. This study investigates the petrogenesis, provenance, tectonic setting, and potential link to uranium mineralization of Middle–Late Mesozoic clastic sedimentary rocks from the Fengzhou Basin and surrounding areas, SCB. Field and petrographic observations reveal litharenite, arkose, and wacke, mostly cryptocrystalline and variably c
