Sedimentary basins

 A. A river-fed clastic system in a humid tropical setting (Fig. 1) experiences a cycle of relative sea-level change (from high to low to high) that exposes the entire continental shelf during lowstand. Discuss the likely origin and types of clay minerals, and the eogenetic processes and products in a range of depositional environments during the sea-level cycle, with specific reference to key stratigraphic surfaces and systems tracts. Furthermore, comment on how the diagenetic features, and porosity and permeability will change after 4 km of burial.
