Ruin marble

Ruin marble exhibited in the Natural History Museum, London

Ruin marble is a kind of limestone or marble originating mostly from Florence territory that contains light and dark patterns mainly gray, brown and reddish, sometimes also blue and black, giving the impression of a ruined landscape painting. The patterns (similar to Liesegang rings) develop during diagenesis due to periodic rhythmic precipitation of iron and manganese hydroxides from oxidizing aqueous fluids restricted laterally by calcite and clay filled joints.[1]
