what can these rocks be?

Recommended Posts

It looks like the ore of lead and zinc. The shiny grey crystals are galena (lead) and the green crystals are sphalerite (zinc). The tiny white crystals are calcite.

All of your rocks look to be the same stuff. Some more crystalized than the others.

I think a better photo may help, you posted 7 of the same image. maybe take it outside on a sunny day and get a closeup if possible.  But to me it looks more like a pegmatite with k-feldspar and biotite but a better photo could change my guess.

You need to take better pictures. Go outside in natural light and  photograph them.

In the textbook terminology its a granite.  Very nice looking Biotite in that sample.
