This contribution presents (i) an overview of how the characteristics of sedimentary facies (composition, grain size distribution, and texture) control the morphology and spatial distribution of stylolite networks, revealing that muddy versus grainy facies and the skeletal component size are the primary controls on the degree of stylolite network connectivity; and (ii) an analysis of how bedding-parallel stylolites may act as barriers and/or conduits for fluids depending on the characteristics of their host rocks, the stress state, fluid pressure, and the forces that drive fluids. This analysis is based on outcrops from the Benicàssim area (Maestrat Basin, Eastern Spain).

摘要

This contribution presents (i) an overview of how the characteristics of sedimentary facies (composition, grain size distribution, and texture) control the morphology and spatial distribution of stylolite networks, revealing that muddy versus grainy facies and the skeletal component size are the primary controls on the degree of stylolite network connectivity; and (ii) an analysis of how bedding-parallel stylolites may act as barriers and/or conduits for fluids depending on the characteristics of their host rocks, the stress state, fluid pressure, and the forces that drive fluids. This analysis is based on outcrops from the Benicàssim area (Maestrat Basin, Eastern Spain).
