Registrations close Tuesday 14 July.

This event is brought to you by the AusIMM Adelaide Branch, our 2020 Branch Partners of Bureau Veritas & OZ Minerals, our 2020 Technical Lunch Partner, Thermo Fisher Scientific, and is worth 1 PD hour.

Please come and join guest speaker Dr Carl Spandler, Associate Professor in Earth Sciences at the University of Adelaide, as he presents his talk titled Geology and Tectonics of Australian Rare Earth Element depositsat the AusIMM Adelaide Branch July Technical Event. We are pleased to announce that we will be returning to our physical events held at the beautiful Adelaide Pavilion. Get in quick though as numbers are strictly limited to a total of 55 attendees due to restrictions.

Prior to Carl’s talk we will hear a short presentation from Ben Forrest, honours student studying geophysics at the University of Adelaide, titled ‘Tracking waste in a sub-level cave operation using geochemistry’.

Please join us as Carl & Ben re-start our face-to-face technical lunch series for 2020 and for what promises to be another fantastic event!

Tech Talk Overview

Australia is host to a diverse range of rare earth element (REE) ore deposits, and therefore is well placed to be a major supplier of REE into the future. This talk presents a review of the geology and tectonic setting of Australia’s hard-rock REE resources. The deposits can be classified into four groups: 1. Carbonatite associated; 2. Peralkaline volcanic associated; 3. Unconformity related, and; 4. Skarns and iron-oxide-copper-gold (IOCG) related. The majority of these deposit groups are directly or indirect related to continental alkaline magmatism, with hydrothermal transport and concentration of REE being important in some cases.

The vast majority of Australia’s REE deposits formed in the Mesoproterozoic in intra-continental settings in association with crustal-scale fault zones or structures that acted as transport conduits for ore-forming magmas or fluids. In general, Australia’s inventory of REE deposits is similar to global record. Globally, the Mesoproterozoic appears to be a particularly productive time period for forming REE orebodies, due to favourable conditions for generating ore-fertile magmas, and favorable preservation potential due to a general lack of aggressive continental recycling (i.e., active plate tectonics).

Presenter

Dr Carl Spandler was recently appointed to the University of Adelaide under the top talent initiative. He uses petrology and geochemistry to research the evolution of the Earth’s crust and mantle, and the formation of metalliferous ore deposits. His areas of expertise include microanalysis of trace elements and isotopes in minerals within their context in rock formations. His current research focuses on understanding how and where ore deposits of critical metals, such as the rare earth elements, are formed in the Australian continent
