Isopach maps of three Mesozoic intervals: a TMa-BMa (Upper Jurassic), b BMa-TMk (Middle and Lower Jurassic and Upper Triassic) and c TMk-BMz (Middle and Lower Triassic). Thickness is calculated as true vertical thickness. The faults shown are those that offset the upper horizon of each interval. All three maps reveal an abrupt increase of thickness across the SFZ, from west to east. The TMk-BMz map also shows an increased thickness within the Unterlören Graben with respect to the area east of the RFZ
