Structural and textural characteristics of HP–LT rocks from the AC. (a) Blueschist outcrop in the AC. (b) Nematoblastic texture defined by Na-amphibole, epidote, chlorite, and rutile/titanite. (c) Elongated rutile inclusions within Na-amphibole, which are also aligned parallel to the NE-SW foliation (d) Garnet exhibiting a poikiloblastic texture, with inclusions of Na-amphibole, epidote, and titanite/rutile. (e) Massive retrograde eclogites in contact with garnet-bearing mica-schists in the AC. (f) Retrograde eclogite surrounded by segregation structures. (g) Granoblastic texture in a retrograde eclogite, with garnet, clinopyroxene, rutile, epidote/zoisite, and amphibole. (h) In the retrograde eclogite, epidote/zoisite is oriented perpendicular to the NE-SW foliation. (i); Garnet-bearing mica-schist outcrop in the AC. (j) Epidote-rich bands parallel to the NE-SW main foliation in the blueschists. (k) Garnet, plagioclase, and quartz veins cutting through retrograde eclogites. (l) Withe mica, quartz, and plagioclase stromatic structures within retrograde eclogites.
