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

Figure 4

Permeability across incipient 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 (a) of the FIE fault, which cuts through packages of evenly distributed clay layers and (b) the FIU fault, which cuts through packages with unevenly distributed clay layers. Fault orientation is denoted in right hand rule with red text, whereas bed orientation is in black text; permeability normalized for bed thickness for the (c) FIE fault and (d) FIU 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 FIE fault and (f) the FIU fault. Color meaning is denoted in the legend below.
