Ruin marble
Appearance
Ruin marble is a kind of limestone or marble that contains light and dark patterns, giving the impression of a ruined cityscape. The patterns (similar to Liesegang rings) develop during diagenesis due to periodic rhythmic precipitation of iron hydroxides from oxidizing aqueous fluids restricted laterally by calcite filled joints.[1]
