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.

Aims:
– To strengthen understanding of clastic and carbonate diagenetic processes and
products, and their relationship to sequence stratigraphy
– To improve scientific writing skills and synthesis of appropriate published literature in
(limited starting literature on Minerva)
– To place diagenetic processes within sedimentary basin analysis
Essay questions:
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.
Figure 1: A cartoon of a typical configuration of a river-fed clastic system in a humid tropical
setting. This is drawn during highstand conditions with a flooded shelf.
B. A rimmed carbonate platform in a humid tropical setting (Fig. 2) experiences a cycle
of relative sea-level change (from high to low to high) that exposes the entire
platform during lowstand. Discuss the eogenetic processes and products in a range
of platform 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.

humid tropical setting. This is drawn during highstand conditions with a flooded shelf.
