Exposed Units: Huntley Hill Formation


This quarry and the small adjacent pit are now very overgrown and the exposure limited.  The rock here is the Silurian Huntley Hill Formation, which consists of very coarse-grained sandstone containing pebbles of quartzite, pink feldspar and rare brachiopod fossils. The unit is thought to have been deposited in shallow marine conditions near to a shoreline.

The quarry itself is situated on the north east side of the May Hill Dome structure, a regional fold of Ordovician and Silurian sediments bound by the Blaisdon fault to the east and Glasshouse Fault to the north.
