No it's not a conglomerate. Conglomerate is a sedimentary rock consisting of distinct rocks that have been cemented together. Usually the smallest pieces run around 2mm and can go up to 20mm or more. it's also called puddingstone. I never heard of Diorite Conglomerate and of course Diorite isn't a sedimentary rock.

The rock above looks like Quartz to me with other stuff mixed in.

No such thing as metamorphosed Quartzite. Quartzite is metamorphosed sandstone so it's just Quartzite.
