PESA WA: Evening Field Trip

Tuesday, March 6, 2018 @ 16:30 - 19:00

Event Categories:

Guest Speaker: Milo Barham

Milo Barham arrived in Perth in February 2012 after completing his BSc (hons), PhD and a year of teaching at the National University of Ireland Galway. Milo worked for five years as a lecturer in sedimentology and stratigraphy at the Department of Applied Geology, Curtin University and is now a Curtin researcher on the Capricorn Orogen, analysing detrital mineral associations to track sediment routing and basin evolution and thus better resolve the geological history of the region. Milo’s past research has focussed on integrating sedimentological, palaeontological and geochemical techniques to elucidate palaeoenvironmental conditions, track basin evolution and contextualise geological and biological events in Earth history. Milo currently sits on the Geological Society of Australia, Western Australia committee and the sub-commission of Western Australian Stratigraphy.

Peppermint Grove Field Trip – 6th March 16:30

PESA WA is holding another field trip!

In a repeat of last years’ interesting evening mini-trip we will visit the Tamala Limestone outcrops at Peppermint Grove (more details below).  Afterwards we will adjourn to the Albion Hotel for a short debrief from our trip leader and a short Q&A session on PESA WA plans for field trips in the rest of 2018.  If you are unable to attend the field trip on the 6th March but are a PESA member interested in having your say on future field trips then come along for 18:00 (ish) to the Albion Hotel.

Peppermint Grove fieldtrip

The Tamala Limestone crops out in a near continuous ribbon for over 1000 km along the southwestern coast of Western Australia. Although dominated by Pleistocene aeolianites, with increasing study and recognition of discrete members, the temporal and environmental complexities of the Tamala Limestone’s deposition are becoming clearer.

At Peppermint Grove, several facies are well-exposed in a relatively small area, allowing for easy investigation of classic Western Australian lithofacies, and broader carbonate-dominated sedimentary features from a variety of paralic depositional environments (aeolian to shallow marine). Improved age constraints and investigation of facies-relationships at Peppermint Grove allow for the generation of simple sea-level curves for this section and a broader discussion of Pleistocene glacio-eustatic sea-level curves and their influence on sediment packages.

Please bring any of these a clipboard, stationary, compass clinometer, hand lens, tape measure, obligatory item for scale, hard hat (for real geologists) water/food as required and money for cash bar/food at Albion Hotel.

Milo will provide some basic notes, a simple worksheet and his expert guidance.

Please download the flyer for maps etc. (please ignore the date and time – the trip is at 16:30 on the 6th March 2018)
