| Age range: | Chadian Substage (CI) — Chadian Substage (CI) | ||
| Lithological Description: | The Raydale Dolostone Formation comprises thinly bedded and nodular dolostones (cementstones) interbedded with siltstone and sandstone. The strata are similar to those present in the Ballagan Formation of the Midland Valley of Scotland and Northumberland Trough. | ||
| Definition of Lower Boundary: | The formation occurs immediately above the Wensleydale Granite, which was reached in the Raydale Borehole at 495.05 m depth. | ||
| Definition of Upper Boundary: | The top of the formation occurs at the base of the conglomeratic Marsett Formation. | ||
| Thickness: | About 30 m. | ||
| Geographical Limits: | Askrigg Block. | ||
