WebMylonite. Mylonite is a fine-grained, compact rock produced by dynamic crystallization of the constituent minerals resulting in a reduction of the grain size of the rock. It is classified as a metamorphic rock. Mylonites can have many different mineralogical compositions, it is a classification based on the textural appearance of the rock. WebThey are characterized by an abundance of Fe-rich minerals like greenalite (Fe-rich serpentine), minnesotaite (Fe-rich talc), ferroactinolite, ferrocummingtonite, hematite, and magnetite at low grades, and ferrosilite, fayalite, ferrohedenbergite, and almandine garnet at higher grades. Manganiferrous.
WebMylonite Ore is an ore that has been mylonitized or "stretched" by metamorphic processes. It is a fine-grained, compact metamorphic rock produced by dynamic recrystallization of the component minerals resulting in a reduction of the grain size of the rock. Mylonites can have many different mineral compositions. Web11 jun. 2024 · Yet in most mylonite, the mineral or minerals making up the matrix usually deform by one or more thermally activated deformation mechanisms that are associated with both non-linear (dislocation creep) and linear (diffusion-accommodated grain-boundary sliding, pressure solution) viscous rheologies ( Schmid and Handy, 1990 ).
