Structural Geology – South Coast excursion 2018

Our yearly excursion to the South Coast for GEOS2190 Structural Geology was a great success. Thanks to Murray Kendall for assisting in the field and food making. Thanks to the Beachcomber caravan park for the friendly venue, and thanks to our students for the fun.

Below are some of my photos. Many more by our students can be found here. If you have more photos of excursion with us don’t hesitate to post and tag with #uongeos


Combined excursions GEOS3170-GEOS3330

This year GEOS3170 – Resource and Exploration Geology provided an excursion to Cobar NSW to explore how the mineralizations are structurally controlled in the Cobar basin. The excursion included mapping of the folded and faulted host rock as well as visits of the CSA and Peak Gold mines to demonstrate how the geology is explored from exploration and production cores. We are very gratefull to both companies to have provided such window into the real work of a mine geologist.

We combined the excursion to Cobar with our usual field trip to Broken Hill for GEOS3330 where the effects of multiple phases of metamorphism and deformation are unravelled. We had the opportunity to get a lecture by Prof. Ian Plimer on the Broken Hill ore body formation. Thank you very much Ian.


GEOS2080 – 2018 – Excursion to South Coast NSW

The semester has started with another excursion to the South Coast for GEOS2080 – Field Geology. Rain on day one at the Bombo Quarry and big swell at Bingie point on the last day. This year the tide was high around mid-day making most of the outcrops less accessible.

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: 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.
