Splay geology
WebThe geology comprises of flat lying beds of cyclic limestone and shale units. Certain horizons within the limestone sequence exhibit fossils, namely corals, brachiopods, crinoids and stromatolites and these form a good marker zone for this particular bench within the former Eastgate quarry which Lady Annabella now works.

Overbank deposits are fine-grained and accumulate vertically. The disturbance of adjacent environments during flooding events leads to deposits containing terrestrial organic debris such as plant matter, and the intervening dry periods allow subaerial bioturbation by roots and burrowing animals. Notable sub-environments within the floodplain include natural levees and crevasse splays.

A crevasse splay is a sedimentary fluvial deposit which forms when a stream breaks its natural or artificial levees and deposits sediment on a floodplain. A breach that forms a crevasse splay deposits sediments in similar pattern to an alluvial fan deposit.
