Calculating Shale-Gouge Ratio - a worked example

Part of The Shear Zone Channel. Shale-Gouge Ratio (SGR) is a widely used, easy-to-calculate parameter that predicts the make-up of deformed materials entrained along faults in sedimentary basins. It deals with multi-layer successions of sandstone and shale (i.e. siltstone-claystone) layers. The results can be mapped onto fault surfaces to forecast their ability support buoyancy pressure differences in formation fluids. See other videos on this channel to find out more about fault rocks and the visualisation of juxtaposition across faults.
