The fireplace on the west wall is a fine example of a marble. In this country stone masons call a limestone which takes a polish a marble but this is not scientific accuracy but colloquial use. However this is an imported red marble possibly from Italy. It shows good calcite veining and secondary calcite (CaCO3<\/sub>) infilling of dissolved shell material. The veining occurred after the deposition and alteration of the rock, as it cuts through original structures. This can be used as a relative dating technique. The hearth of the fireplace is a local possibly Austwick sandstone of Silurian age. Have a look at the hearths of all the fireplaces in all the rooms. Are they the same material?<\/p>\n
