WebFoliation is a term used to describe a geological feature that is commonly found in metamorphic rocks. This term refers to the parallel alignment of mineral crystals, grains, or structural features within the rock itself. In other words, foliation describes the layered appearance of the rock. WebThe most basic pattern of foliation in a shear zone is known as sigmoidal oblique foliation. Thisis the fabric that is produced by the flattening of particles or domains (clasts, mineral grains, etc.)in the protolith (the original rock), when heterogeneous simple shear takes place. temu kitchen mat
