Facies S4: Upper Shoreface
Facies S5: Foreshore and coastal plain
Facies S2: Offshore
transition
Facies S3: Lower Shoreface
Fine to medium grained sandstones
with occasional relict stratification
and strong bioturbation. Low angle
discontinuities and scour-and-fill
structures occasionally observed.
Stratified sandstone with cross- and planar-
stratification and carbonaceous-rich
mudstone, ripple stratified sandstones and
thin coal beds - low preservation potential.
Very fine grained sandstones
with abundant horizontal
burrows.
Sandy mudstone to very
muddy sandstones showing
strong bioturbation.
