Sediment composition and maturity reflect the tectonic depositional setting: rift basins shed feldspar-rich arkose from rapidly eroded basement, trench settings receive immature lithic-rich greywacke, stable beach settings produce mature, well-sorted quartz arenite, and fore-arc basins receive volcaniclastic lithic arenite from the adjacent arc.
Rift basins are associated with Arkose, sourced from rapid erosion of granitic/gneissic basement under fault-controlled relief (i-C). Trench settings are associated with Greywacke, poorly sorted,...
