Visit to Linhay Hill Quarry, Ashburton

An opportunity to visit the E & J W Glendinning owned Linhay Hill Quarry at Ashburton. The quarry shows predominantly dark-grey with some medium-grey well-bedded limestones of the Chercombe Bridge Limestone Formation of Middle and possibly also Upper Devonian age. The lower boundary of the limestone is a major low-angle thrust fault roughly parallel to the bedding on which the limestones have been ‘thrust’over younger slates of the Kate Brook Slate Formation with displacement of many kilometres.

• About 250m thickness of limestone.
• Consistent south-easterly dip in the limestone
• The lower thrust fault contact (Bickington Thrust) with the limestone overlying the younger Kate Brook Slate Formation.
• Exposures of typical Kate Brook Slate Formation
• Unusual large calcite replacement feature in the limestone
• Abundant fossil corals, stromatoporoids and brachiopods in the limestone.
• Shallow solution weathering at the rock surface
• Fossil corals and shells weathered out in near-surface limestone

Followed by a visit in the afternoon to the disused quarries of the Buckfastleigh area.
