oa Numerical and Experimental Evidence for Polygonal Faults in Carbonate Rocks

Polygonal fracture patterns in clastic environments have been first observed in the early 90’s, thanks to 3D seismic. Incarbonate rocks only few examples, e.g. Abu-Dhabi grainstone reservoirs, are observed using seismic attribute techniques. The lack of fossil analogues and the absence of resolvable displacement results in a debate about their origin: differential compaction under low differential isotropic extensional stress or seismic artifact.
