The Hollyford Formation is a rock unit from the Silurian found in the Cratloe Hills, County Clare, Ireland. It is made mainly of mudstone, greywacke, and fine siltstone. These rocks were formed in a deep sea environment, where sediment was carried into the basin by underwater flows called turbidity currents, building up layers over time.[1]
