Mylonite is a fine-grained, compact metamorphic rock produced by dynamic recrystallization of the constituent minerals resulting in a reduction of the grain size of the rock. Mylonites can have many different mineralogical compositions; it is a classification based on the textural appearance of the rock. See more Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones. There are many different views on the formation of mylonites, but it is generally agreed that crystal-plastic … See more • Blastomylonites are coarse grained, often sugary in appearance without distinct tectonic banding. • Ultramylonites usually have undergone extreme grainsize reduction. In … See more • Mylonite photo gallery Archived 2024-11-08 at the Wayback Machine See more Determining the displacements that occur in mylonite zones depends on correctly determining the orientations of the finite strain axis and inferring how those orientations change … See more WebMar 10, 2024 · Separating the Dinwiddie terrane from the Roanoke Rapids terrane are greenschist-facies, highly strained granitic mylonite and bodies of less deformed granite within the Nottoway River fault zone, which is a strand of the eastern Piedmont fault system.
