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

Figure 3

Faults were divided into groups based on the overall architecture. Black layers are representative of claystone, whereas the white beds represent a more competent layer, such as sandstone, limestone, and conglomerates. (a) Incipient faults are usually small in offset (<0.50 m) and are characterized by their lack of fault core; (b) well-developed faults are characterized by the presence of a fault core (in red); (c) complex faults contain two or more fault planes that contribute to an overall more mature fault core.
