In Flimston Bay is a wide section of sea cliff - comprising Limestone fragments in
a cementing material - gash breccia .
----------------
One Possible Theory for this feature :-
Rain / streams dissolve out caverns , in the limestone , the sides and roof collapse ...
and fill with angular limestone fragments in a sandy matrix / calcite cement -
sometimes stained Red , as here ??.
---------------
Or :-
A Fault Breccia resulting from the grinding action of two fault blocks as they
slide past each other . The broken fragments have become cemented together
through the action of water ???
---------------
Or :
An accumulation of desert rubble during the Triassic Period.
--------------
Present marine erosion is now cutting in to the former Karstic Landscape ,
and exposing this rock type.
