| Description: | A dull fawn-grey limestone, containing scattered smooth-surfaced black bodies which include limestone. This specimen is Calciferous Sandstone Series (Carboniferous) in age. BGS Sample Number SL 217. British Geological Survey Petrology Collection sample number S 35897. The rock is composed of very finely divided calcite, locally slightly and irregularly recrystallized, with sparse, small rhombs of dolomite reaching 0.2 mm size. Scattered through the rock are fairly numerous thin shells and shell fragments densely permeated by pyrite. Quartz grains are small and few. Irregular, short veins of limonitic matter and cracks sealed by calcite are common. Many of the fossils are ostracods, either whole or broken and collapsed, and often filled with clear coarsely granular calcite. |
