Last Thursday I took a trip to the Otway Basin with the Monash 3rd year sedimentary short course students. It was a lovely day and we saw some beautiful outcrops. The Eumeralla Formation is volcanilithic sandstone, siltstone, mudstone, mud-clast conglomerate,
with feldspar and quartz grains, and coal: fine to medium grained,
consolidated, well-bedded, cross-bedded; braided stream deposits. It was deposited the same time as the Inverloch sediments in a similar environment.
Faulting with minor offsets - sandstone with finer grained, organic rich beds
A scour filled with muddy rip-up clasts, some spotted this trip were up to 20cm wide.
