Porphyry is a general term that is used to refer to igneous rocks containing relatively large, isolated crystals set in a fine-grained ground mass. This porphyry has pinkish colored clinozoisite crystals in a mass of dolerite. The clinozoisite has replaced but retained the shape of plagioclase feldspar crystals.
