Schistose amphibolite and metagabbro are represented by fine-grained, equigranular rocks of granonematoblastic, nematoblastic, relict gabbro, poikilitic texture.
The compositional banding is reflected by alternating nematoblastic (hornblende) and granoblastic (plagioclase) bands, within which epidote-group minerals and garnet porphyroblasts occurs.
The compositional banding is reflected in alternating hornblende-bearing nematoblastic and plagioclase-bearing granoblastic bands, within which epidote-group minerals and garnet porphyroblasts occur.
The metamorphic units comprise garnet-glaucophane schist (lepi-doporphyroblastic texture), epidote-chlorite schist (lepidoblastic texture), garnet-lawsonite-glaucophane schist and epidotite (nematoblastic texture) (Fig.
