Genetic modelling elements; lithofacies types grouped into channel, upper shoreface and lower shoreface
genetic depositional elements (Image courtesy of Simon Smith)
include conglomeratic, cross-bedded sandstone
and mudstone lithofacies. Figure

shows an
example of several genetic depositional elements
interpreted from core and log observations.
2.4.3.3 Stratigraphic Elements
For models which can be based on a sequence
stratigraphic framework, the fine-scale components
of
the stratigraphic scheme may also be the
