the quartz in the welsh examples is crushed so we aren't talking big lumps and is hard to gauge exact proportions (its been a while) at a guess would say 5% quartz but dont quote me on that x.(Think am getting tired rered last post and meant huge in terms of sheer volume - the mound covered a large area but not huge in proportion) Same as you with the stone ratio tho
but of interest I dug one on Anglesey where the geology was schist same as with you and that was used in the mound
