Natural fracture patterns in carbonate rocks

Geometries of 2 fracture families in a carbonate pavement. Lengths of the fractures have been digitized and stored. The data is collected as part of a fieldwork to characterize natural fracture systems in a folded carbonate formation, with the aim of studying the role between large-scale folding and small-scale fracturing. In addition, the specific data from this outcrop has been used in geomechanical and flow models, focusing on stress-driven aperture modelling and quantification of fluid flow. The data has been digitized using DigiFract software, developed at TU Delft (Hardebol & Bertotti, 2003, Computers & Geoscience)
