What is Differential compaction as a control on depositional architectures across the Maiella carbonate platform margin (central Apennines, Italy) about?

The role of differential compaction as a control in the creation of accommodation and on compaction-modified depositional features and stratal geometries across the Maiella platform margin, has been investigated through a combined analysis of seismic scale outcrops, porosity evaluation and modeling. Geologic evolution and large exposures make the platform margin of the Maiella an ideal place to investigate the effects of differential compaction. A high-relief cemented carbonate platform, a deep basin filled with highly compactable deposits, and a prograding grain-rich succession sealing morphologic differences across the platform margin, represent suitable features for promoting differential compaction. Stratal relationships across the platform margin exhibit evidence of differential compaction-induced effects, such as basinward divergence and thickening of strata, updip pinch-out of wedge-shaped stratal packages, and an anticline hinge. Porosity analysis and modeling indicate that, through progressive loading, mechanical and chemical processes act in concert to destroy most of the depositional porosity. Mechanical compaction appears to have played the greatest part in the total bu
