More magnetic rock

The  rock to the left has the same indentations as the split rock to the right they both attract a small magnet strongly,  i believe they must a be basaltic rock but ive never come across this surface pattern before. Also one was dug from the gavel beds at Stainton the other found in Ormesby beck, but ime certain it originated from the same gravel bed in that location.
