Rock365 : 10 02 2010 : Grinshill White

Day 41 : This is Grinshill White, or more correctly the white facies of the Helsby Sandstone. This Lower Triassic sandstone from the Cheshire Basin is the lateral equivalent of the Hollington Sandstone (Days 35 and 36) from the Needwood Basin and the Bromsgrove Sandstone (Day 34) from the Stafford Basin. All of them used to be the Lower Keuper Sandstone. This is from the Grinshill Quarry itself.
