1 describes a type of rock consisting of broken pieces of other rock
The initial stage of sedimentation in these basins was characterized by terrestrial and shallow marine deposits that consist of both clastic and carbonate deposition.
The resulting channel bars will have provided more extensive areas of clastic substrates, which will have favoured the fern-pteridosperm complex.
The predominant fill-type is a clastic-textured, orange/brown biomicrite containing abundant comminuted brachiopod material.
The system controlling the composition of clastic sediments.
Extensional faulting created local accommodation space for the redeposition of material and focussed clastic supply routes into the basin at transfer zones.
Stratigraphically diagnostic fossils are scarce or absent in many of these clastic sequences, which furthermore differ markedly in lithological succession between different outcrop areas.
Clastic layers up to 10 cm thick are common within thick seams.
This may partly be because the pteridosperms were probably growing on the levees and other raised areas in the forest with clastic substrates.
