How does porphyritic texture look like?

Answer:
There are 2 or more very distinct gain sizes.
The smaller grains are called phenocrysts and
the material around it is called matrix or
groundmass. The phenocrysts are 0.3 - 5 mm.

To truly see what a porphyritic texture looks like
just search on google images and you'll see a nice
example along with a diagram that explains it.
