Description of eclogite

WebAug 4, 2024 · In natural eclogite, omphacite commonly shows evidence of plastic deformation whereby the foliation and lineation of eclogite are defined by a strong CPO and SPO of omphacite grains. Therefore, the rheological behavior of eclogite is dominated by the mechanical behavior of omphacite [ 44 , 47 ]. WebEclogites are divisible into three groups based on mode of occurrence: Group A, inclusions in kimberlites, basalts, or layers in ultramafic rocks; Group B, bands or lenses within migmatite gneissic terrains; Group C, bands or lenses within alpine-type metamorphic rocks.
