Abstract
Summary
Faults and fractures are mechanical discontinuities that develop at all scales due to brittle deformation of rocks. Because of their complex geological history, they can be sealing or conductive to fluids. Moreover, this geological complexity results in very heterogeneous fracture systems both in orientation and spatial distribution. Description for the total range of size is difficult to predict from subsurface data or well data. Surface analogues are used to overcome this difficulty. Here, the focus is made on the folds/faults/fractures of the Westphalian interval of the Saar-Lorraine coal basin. This interval is the richest in coal seams and is folded.
