Ref. 2751:Bioclastic accumulations composed of crinoids, brachiopods, molluscs, spongiomorphs and scleractinian corals at Pardonet Hill. These small buildups (~100 to 500 m3) have planar bases and broadly convex tops (3 small reefs). These mounds are interpreted as small patch reefs composed of packstone, bioclastic floatstone/rudstone and carbonate breccia intercalated with mixed siliciclastic carbonate sediments deposited in a shallow subtidal setting.
