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.
However, most of the studied metabasites are nematoblastic amphibolites, consisting of Amp, Ep, Rt, Chl, Qz [+ or -] Grt [+ or -] white-mica [+ or -] Cb and Ilm [+ or -] Ttn after Rt.
The textures in the rocks are nematoblastic and granoblastic.
The textures found in the rocks are nematoblastic, granoblastic and porphyroblastic.
The nematoblastic texture is defined by its preferential orientation of hornblende (Figure 3e).
