... is consistent with outcrop measured UCS located in the same region. The importance of layered, variable-strength rocks to natural fracture development is observed in an outcrop exposure of the Austin Chalk in central Texas. Chalk-rich facies (high UCS) were more fractured and had a broader deformation area...

.... In particular, the strength and related microfabric properties of these rocks. Three microfabrics (MFs) were targeted in this study; those are MF-1: microcrystalline mudstone, MF-2: Intraclastic skeletal peloidal grainstone, and MF-3: Thinly-laminated microbialites. These samples were picked from a well core...

... that are ubiquitous in nature. Here, we employ triaxial direct-shear to investigate the hydromechanical properties of fractures that are created and maintained at in-situ stress conditions. Our results show that in-situ created fractures are rougher, leading to higher frictional strength and more tortuous transport...

While such terminology is often used in a casual sense, there are at least two relevant mechanical definitions. One definition compares the peak and residual strength...
