This blog focuses upon stylolites which are structures that either form during burial or by later tectonic movements and have a serrated appearance on rock surfaces.
This blog outlines a simple method to predict fracture distribution from geomechanical principles including the common observation that thicker beds usually have less and more widely spaced fractures than thinner beds.
Faults often have more than 1 slip surface. In this blog, we present a major fault with multiple surfaces which juxtaposes the Upper Devonian Sediments (at arbroath) against the Lower Devonian Sediments.
