2.04.6(2)(a)
attains a thickness of 150 to 200 feet in the area.
The Lower Coal D:ember consists of interbedded sandstone,
siltstones, shales and coal. The unit averages 270 feet in
thickness and contains three recognized persistent coals in
its lower part: the A, n and C seams. The Lower Coal Member
is almost always capped by a massive sandstone unit which
varies in thickness from 20 to 225 feet. This sandstone is
similar in nature to the Rollins but shows much more
variation in thickness and is more difficult to correlate.
The top of this sandstone marks the bottom of the upper
coal member.
The Upper Coal Member contains approximately 220 feet of
shales, siltstones, sandstones and 3 persistent coals
(recognized as the D, E and F seams). This member displays
sequences of disturbed bedding (attributed to preconsolidational
slumping and bioturbation) in the non-coal units. The shale to
sandstone ratio increases relative to the lower coal member,
and the sandstones appear to be less continuous than those in
the lower coal member, possibly due to a greater fluvial
influence in the depositional regime of the upper member.
' The Farren Piember consists of a thick sequence of interbedded
sandstone, siltstone and shale with a few lenticu lar coal seams.
This unit is of non-marine origin and of minimal economic
t importance. Sandstones in the barren member are the uppermost
' cliff-formers across the area, but are lenticular and of
limited lateral extent in outcrop.
' Cross sections are shown on drawings 2.04.6(?_)(a)-1, N-S cross
section and 2.04.6(2) (a)-2, E[a cross section, ?'he locations of the
' cross sections and drill holes are shoran on P?ap 2.04.6(2)(a)-3. Also shoran
on this map is the surface geology and the C and P coal seam outcrops.
