GEOS2190 – Excursion to South Coast

Here are some photos of our structural geology excursion to Potato Point, South Coast NSW. It’s been great. Thanks everyone!


GEOS1050 – Excursion to New England

Here are some photos from the 2017 excursion to New England.


Broken Hill 2017

GEOS3330 excursion to Broken Hill provided a new opportunity this year. For the first time since I started doing this excursion, it rained on the field area during the day. Not enough to make us stop, or worry too much about the dirt road and the creek… Also, with the rain some foliations became a lot easier to spot while other almost disappear.

Following our GEOS2080 excursion to South Coast I posted some photos on social media which can be found using the hashtag #uongeos. If you have photos to share from our excursions please do post and tag. You can be specific and use #uongeos2080 or #uongeos2190 as well.

GEOS2190 – Potato Point – South Coast NSW

GEOS2190 – Structural and Field Geology changed its location in 2016!

Instead a mapping on km-scale in the Hill-End trough, we travelled to Potato Point and Mystery Bay in South Coast NSW. The objective was the mapping of bedding and younging in simply folded Ordovician turbidites of Potato Point to build a cross-section, and stereonet analysis. This exercise really pushes the idea that structure and stratigraphy must be worked out together in folded areas.

Then a short day at Mystery Bay introduced the notion that many areas have been folded several times. Next step, the multiply folded and metamorphosed meta-turbidites of Broken Hill.

My friend Stefan Vollgger from Monash Uni made the basemap used by the students with his UAV. It worked great. A 3D model is also available here: https://skfb.ly/ToHY Check it out!

UAV map

I have performed a mapping of a headland with my friend Stefan Vollgger from Monash University. I will bring the students there for my second year structural geology course (GEOS2190). We did fly the UAV some 40m above the platform and were able to get a high resolution map of the headland to be used as a base-map.

UON Earth Science will get its UAV (drone) very soon. But we will need to sort out the licences as well before we can continue.

Life and death in the Permian: Swansea heads

Last post I did not include any photos of Swansea head. Here are some good shots of our students trying to study the rocks despite the high tide.

Thanks Maxime for the photos.
