    The New Red Sandstone chiefly in British geology is composed of beds of red sandstone and associated rocks laid down throughout the Permian (280 million years ago) to the end of the Triassic (about 200 million years ago) that underlie the Jurassic-Triassic age Penarth Group. The name distinguishes it from the Old Red Sandstone which is largely Devonian in age and with which it was

    Hematite and magnetite are two iron oxide minerals. Most iron ore deposits consist mainly of hematite magnetite or both. Iron oxide concretions iron oxide nodules and ironstones are often mistaken for meteorites because their unusual shapes catch people s attention and they are denser than most other rocks. Hematite concretions form by precipitation of iron oxide from iron rich solutions.
