| Description: | A grey, compact oolitic limestone with a buff crust. In thin section the ooliths are found to be 0.5 - 1.5 mm in diameter and frequently have as kernels irregular pieces of shell or echinodermal plate and spine and, less commonly, earlier ooliths with limonitized or pyritized borders. They are embedded in a very fine-grained matrix of calcite containing a few thin-walled microshells and scarce tiny grains of quartz. Subordinate detrital constituents include rolled shell fragments and rolled pebbles of oolite. Limestone, micrograined, oolitic. SL0253. Britrocks S35353. Magnification x40. Light PPL. |
