Microbial Limestone

This red laminated rock is microbial algal limestone, which represents the oldest life form in Britain and Ireland. It was produced by microbes which grew in mats over the rock, fixing limestone and then growing over the earlier layers. The red colour is caused by staining from the overlying sandstones.

    Re your question about the columns on the Stanford Museum - they are Ionic rather than Corinthian.

    I've always liked limestone - it's the best way to get an inkling of the depth of time.

    We have plenty of limestone here in Yorkshire but I think nothing quite like this. Not I must add that I can claim any knowledge of geology except perhaps of the very basic kind.
