... 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...

..., block-in-matrix mixtures, and so on, all of which I bundle into the geologically neutral term “bimrocks” (short for “block-in-matrix rocks”). The competing theories of the processes of melange formation are dauntingly complex but, simply, melanges are found in the mountainous areas of previous...

... amount of exotic blocks in the block-in-matrix structure or bimrock (Lindquist & Goodman, 1994 ). The influence of bimrock rheology on metamorphosed chrome spinel needs further investigation. The compositions of the studied Cr-spinel, in conjunction with BSE imaging of Cr-spinel, indicate...

... 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 to be related to the closure of the Tethys Ocean...

... ‘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...
