TS3 (Fig. 7). Allostratigraphic unit 2 is 65 to 127 m
thick and records at least six 10 to 24 m thick and
up to several kilometres wide heterolithic upward-
coarsening or upward-fining units (UCU or UFU)
composed of laterally amalgamated facies associa-
tions. The upward-coarsening and upward-fining
units are separated by local flooding surfaces (FSb-e)
overlain by less than 1 m thick shale beds with
dominantly terrestrial palynomorphs and subordi-
nate amounts of marine palynomorphs (Fig. 9). The

Description: Progradational to aggradational
architectural elements

The sandy heterolithic allostratigraphic unit 2
overlies the flooding surface FSa at all the localities
and is topped by either TS2 or the combined SU1/
