I spent a second day at the Exploration Data Centre (EDC), logging sedimentary structures and identifying facies: distinct rock units that form under different environmental conditions. From what I've identified so far, it appears to have been very low energy, with slow flowing rivers and lakes.
I photographed 300 m of core that I logged, which only took about 2.5 hrs. Sheesh! But it is extremely useful in case I need to re-define or re-examine particular facies.

Logging rock core from the Winton Formation near Isisford: the core starts at the bottom left of each tray, and progresses down hole to the right.
So all in all, I had a very productive 2 days at the EDC. The facility is well organised and maintained, and the staff are friendly and helpful, so I'd recommend it to anyone needing to examine drill core!
