Regolith in Australia: A global and multidisciplinary view

The Australian Regolith Geoscientists Association merged with the GSA in 2019 to become the Society’s newest Specialist Group, the Australian Regolith Geoscientists Alliance (ARGA). To celebrate this, ARGA is proposing a special Regolith Symposium for the upcoming AESC 2021. ARGA builds upon the legacy of several decades of Australian regolith research and promotes the important role that regolith science plays in Australia.

This Symposium aims to promote the science of regolith with a holistic approach including and beyond geoscience, with special emphasis on the emerging international critical zone research. In this Symposium, we invite research contributions that showcase or assist elucidating a better understanding of novel and innovative approaches to the research on regolith, spanning from environment, hydrogeology, economic geology, archaeology, landscape evolution, sedimentary systems, agriculture and soil quality, geoheritage, geochemistry, mineralogy, to surface processes, and technical challenges to greenfields and brownfields technologies for mineral exploration.

The ARGA Symposium includes following four sessions:
Session 1: The physical controls on water movement and regolith-hydrogeochemistry (Conveners: Leah Moore, John Keeling, and Carmen Krapf)
Session 2: Mineral exploration in and through the critical zone (jointly with MinEx CRC; Conveners: Ian Roach, Anna Petts and Walid Salama)
Session 3: Regolith and Landscape evolution (Conveners: Ignacio González-Álvarez, Carmen Krapf, Nadir de Souza)
Session 4: Planetary and regolith oddities (Conveners: Nadir de Souza, Savannah McGuirk, and Ian Roach)

In addition to the Symposium we will offer:

  • 2-day fieldtrip “Salt distribution in different parts of the Tamar landscape due to effects of deep bedrock weathering” (led by Leah Moore et al.)
  • ½ or 1-day fieldtrip “Periglacial deposits in the Hobart area” (led by Leah Moore et al.)
  • Social drinks function following the Symposium

    1 November 2019

  • ARGA has joined the Geological Society of Australia! By a majority vote at the 2018 ARGA Conference in Wallaroo, members voted to join with the GSA as a Specialist Group. The ARGA Committee has been working towards this since the vote, and in November 2019 ARGA was accepted by the GSA as its newest specialist group. ARGA has changed its name to the "Australian Regolith Geoscientists Alliance", but keeps the same acronym (ARGA) and the same website.

    Specialist group membership for GSA members is set at $5.50 per annum initially, but ARGA members who do not wish to join the GSA can still come along to the ARGA field conferences as a "Friend of ARGA" and pay the usual conference fees. Non-GSA members are also welcome to register for any ARGA symposia at GSA conferences at a day rate as you would for attending any other GSA Specialist Group symposia.

    The ARGA Comittee is very excited about the merger, and the benefits that joining the GSA will bring.
