... engineers. Mélanges are the most intractable bimrocks (block-in-matrix rocks), complex geological mixtures composed of hard blocks of rocks surrounded by weaker matrix, and are famously exemplified by those within the Franciscan Complex of Northern California. Bimrocks also include olistostromes...

... related to melange formation. As well, there are a confusing number of geological terms for chaotic fabrics: melanges, olistostromes, sedimentary breccias, block-in-matrix mixtures, and so on, all of which I bundle into the geologically neutral term “bimrocks” (short for “block-in-matrix rocks...

... slope ( Leopold and Völkel, 2007 ), is frequently a challenge for researchers given its bimrock-like fabric ( Medley, 2001 , 2002 ). The formation of extensive colluvial deposits on steep slopes in southwest China poses a major hazard to the construction of important hydropower projects ( Liu et al...

... entirely within a serpentinite mélange. Assuming this, the strength (or the weakness) of serpentinite mélange might differ owing to the variable amount of exotic blocks in the block-in-matrix structure or bimrock (Lindquist & Goodman, 1994 ). The influence of bimrock rheology on metamorphosed chrome...

... differ owing to the existence of variable amount of exotic blocks in the block-in-matrix structure or bimrock (Lindquist & Goodman, 1994 ). Given the configuration stated above, which is based on the coexistence of intraoceanic subduction types, the early tectonomagmatic episode is considered...

... ‘bimrock’ for rock bodies that contain competent blocks of varied lithologies, embedded in sheared matrices of weaker rock. Medley (1994 , 2001 ) introduces this term in a geological engineering purpose and defines the bimrock as ‘a mixture of rocks, composed of geotechnically significant blocks...
