Petrophysical Properties and Microstructural Analysis of Faulted Heterolithic Packages: A Case Study from Miocene Turbidite Successions, Italy

Figure 5

Permeability across well-developed faults in different styles of multilayer package. Fault orientation is denoted in right hand rule with red text, whereas bed orientation is in black text: line drawings of (a) the FWE fault, which cuts through packages of evenly distributed clay layers, and (b) the FWU fault, which cuts through packages with unevenly distributed clay layers. The grey block is representative of travertine deposit that covers the outcrop; permeability normalized for bed thickness for (c) the FWE fault and (d) the FWU fault; variation of permeability measurements shown in a box and whisker plot, in order to show the high variability across the damage zone in the hanging wall (HW DZ), the fault core, and the damage zone of the footwall (FW DZ) in (e) the FWE fault and (f) the FWU fault. Color meaning is denoted in the legend below.
