Sometimes sand contains new minerals or mineral aggregates that were non-existent in the source rocks. Notable example is a clay mineral glauconite which forms in marine sand and gives distinctive dark green color to many sand samples. In some instances glauconite in sand may come from disintegrated glauconitic sandstone nearby, but eventually it is of marine origin anyway.
