.... At this locality, the upper 50 m of the Mount Copleston volcanics consist of matrix-supported volcaniclastic diamictite of volcanic gravel and cobbles in a matrix of volcanic grit. It is unclear if this deposit is a debris flow or a glacial diamictite formed of reprocessed volcanics. We have included this deposit...

Because sea levels are low during glacial and interstadials periods, most fossil corals have been exposed to meteoric waters for a significant portion of their post-depositional history. This exposure creates the potential for these corals...
