Porphyry is a general term that is used rather loosely for igneous rocks which contain relatively large isolated crystals set in a fine-grained groundmass.
The porphyry pictured here has pinkish coloured clinozoisite crystals set in a ground mass of dolerite.
The clinozoisite has replaced but retained the shape of plagioclase feldspar crystals.
