This two-day online course aims to introduce the fundamentals of regolith, landscape evolution, mapping, and techniques used in modern exploration geochemistry with a focus on Australian settings (semi-arid mainly). Each day will feature 4 x ~90 min sessions and time allocated for discussion. The format will be PowerPoint presentation with and aim for open communication, with input from participants highly encouraged to share knowledge and experiences. We may have a couple of working examples and exercises to solidify key concepts. Access to a laptop may be useful but not essential and materials will be provided as required. A copy of slides/notes and related materials will be provided on the day.

Day 1

1.      Terminology and development of regolith profiles (Walid Salama)

2.      Regolith-landscape processes and evolution, and the identification of key materials (Walid Salama)

3.      Geochemical mapping (David Cohen)

4.      Geochemical exploration approaches and sampling media in residual areas-case studies (Walid Salama)

Day2

5.      Geochemical exploration approaches, dispersion mechanisms, and sampling media in areas of transported cover-case studies

         (Walid Salama)

5a.   Cover in glacially influenced terrain settings and other weird cover types (uncommonly used/encountered in Australia at least

6.      Analytical methods/QAQC considerations (limitations, partial/total extractions, handheld devices) (Ryan Noble)

7.      Testing ultrafine soils to improve near surface exploration through cover (Ryan Noble)

8.      Putting results in landscape context (Next Gen analytics/LandScape+ as an example of how to do this) (Ryan Noble)
