Australian Regolith Geoscientists Alliance (ARGA)


ARGA - the GSA's Newest Specialist Group

The Australian Regolith Geoscientists Association (ARGA) has merged with the GSA to become the Society’s newest Specialist Group, the Australian Regolith Geoscientists Alliance (keeping the same, well-recognised acronym of ARGA).

What's new?
21-26 June - Goldschmidt Hawaii 2020: Regolith-related session 08a: Metal Mobility in the Critical Zone and its Implications to Geochemical Exploration in Weathered Terrains
Shallow mineral deposit discoveries are becoming less common and those world-class deposits are either mined out or decreasing in production. One of the fundamental challenges for mineral exploration industry in this century is targeting deeper concealed mineral deposits under the critical zone. The increase in demand for mineral resources worldwide is driving investment in developing new geochemical exploration methods for vectoring concealed mineral deposits in deeply weathered and covered terrains. Extensive older terrains of Australia, India, West Africa, Brazil and China are deeply weathered and others such as Canada and Fennoscandia are overlain by recent glacial sediments. Thus, geochemical signatures of the mineralisation and the host rock can be obscured by deep weathering and transported cover providing challenges for exploring these terrains. The purpose of this session is to bring together a number of contributions showing interdisciplinary integrated approaches for understanding physical and biogeochemical mechanisms for metal mobility from the mineralised source through the critical zone to surface. The session also invites topics discussing recent advances in developing or improving geochemical and analytical (isotopic and dating) techniques, numerical modelling and experimental methods applied for mineral exploration through the critical zone. Geochemistry of supergene ore deposits, indicator mineral chemistry, and hydrogeochemical studies are also part of this session.
Goldschmidt is the foremost annual, international conference on geochemistry and related subjects, organized by the Geochemical Society and the European Association of Geochemistry.

What does ARGA do?

ARGA promotes the important role that regolith science plays in Australia. Regolith geoscience is critical in the Australian context, as more than 70% of the continent is covered by transported material and deep weathering profiles. The alliance has existed since the ending of the Cooperative Research Centre for Landscape Environments and Mineral Exploration (CRC LEME) in 2008. It builds upon the legacy of decades of Australian regolith research, including work at universities, state and Australian government agencies that culminated in CRC LEME.

We welcome all people who have an interest in regolith geoscience and its many facets, including geology, geochemistry, geophysics, geochronology, mineral exploration, pedology, biology, hydrology, meteorology, agronomy, forestry, etc.

The objectives of ARGA are to further the study of regolith geoscience and its allied disciplines (including Critical Zone studies) by:

  • facilitating the exchange of information among members of the association, and in general for all those interested in regolith geoscience
  • stimulating interest in regolith geoscience
  • encouraging the practical applications of regolith geoscience research
  • providing high-quality education and training
  • promoting regolith geoscience to the broader community.

ARGA’s goal is to promote research and education in regolith geoscience by fostering interaction and knowledge exchange between academia, government agencies, the minerals industry and the general public. To achieve these goals as a Specialist Group, ARGA facilitates:

  • an ARGA Symposium and/or field workshop at the next Australian Geoscience Council Convention (AGCC) and/or the Australian Earth Sciences Convention (AESC), together with organisational and editorial support
  • a biennial conference and field trips in opposite years to the AGCC and/or AESC, with extended abstracts volumes
  • the Keith Scott Memorial Award for best presentation at the biennial ARGA conference
  • student travel sponsorship to attend ARGA conferences and student prizes for ARGA conference presentations
  • special issues of AJES
  • ad hoc field trips and training courses for interest groups on a demand basis
  • the ARGA website (
