| Description: | A flesh-coloured, porous mass of tufa, composed of a turbid mass of very fine-grained calcium carbonate showing irregularly concentric growths from many centres. The open aggregate formed by these growths is partly filled by a brownish, slightly ferruginous marl containing small organic debris and scarce grains of quartz and feldspar. Tests on the material give the ordinary refractive index for calcite. SL0254. Britrocks S35354. Magnification x40. Light XPL. |
