Whilst walking in Scotland we sat and had lunch on the remains of an old lead mine. We picked up a few rocks and saw that some had blue/grey square crystals. The rocks were quite heavy, white on shiney. Firstly were the blue crystals lead? and secondly what were the carrier rocks. Sorry no photo!

If you were near Elvanfoot, it's a fair bet it was lead.

It's an even better bet that it was galena- a lead ore.

I think most of the galena I have seen was in among quartz, but I'm not sure.
Is there a geologist in the house?

square crystals+blue grey color- no doubt it's galena (lead sulfide).
White carrier rocks (we use the jargon matrix or gangue) most likely quartz, though calcite, barite or anglesite are also possibilities.

That's what I was thinking as well...Galena.
