Pressure solution-fracturing interactions in weakly cohesive carbonate sediments and rocks: Example of the synsedimentary deformation of the Campanian chalk from the Mons Basin (Belgium)

► Pressure solution-fracturing interactions in weakly cohesive micritic carbonate materials. ► Synsedimentary deformation of the Campanian chalk from the Mons Basin (Belgium). ► Development of a dip-slip normal fault in a near-surface marine environment. ► Diagenetic modifications in reservoir qualities, transport properties and nannofacies. ► The diagenetic modifications result from significant mass transfers and volume changes.
