Webinar: Understanding Magmatic Fractionation Processes using Multielement Geochemistry

1
PD Hours
It is now commonplace for mining and exploration companies to analyse drill core and/or chips using a 4 acid digest ICP-MS method. In addition to plotting the commodity metals, companies should also use this data as an aid to improving the identification of rock types, alteration mineralogy and magmatic processes. 

About this event

It is now commonplace for mining and exploration companies to analyse drill core and/or chips using a 4 acid digest ICP-MS method. In addition to plotting the commodity metals, companies should also use this data as an aid to improving the identification of rock types, alteration mineralogy and magmatic processes. There are a few simple plots from the immobile trace elements in the ICP-MS suite that are reliable indicators of fractionation processes and “magmatic fertility” in different geological environments. Examples will be presented from porphyry copper (East Lachlan), Archean gold (Yilgarn), and mid crustal melts (Tasmanian tin granites).

Speakers

Scott Halley

BSc, PhD
Scott has consulted to more than 150 mining and exploration companies in more than 25 countries in the last fourteen years. Having worked as an exploration geologist for 20 years prior to specialising as a geochemist means that Scott understands how geochemistry can be practically and effectively applied to exploration and mining problems. Advances in technology mean that there are significant changes in the quality of commercially available geochemical and mineralogical analysis methods every few years. One of Scott’s aims is to ensure that his clients are using the most appropriate methods and deriving the full benefit from their data.
As well as consulting, Scott is a regular presenter in the CODES MSc (Econ Geol) short course series, and a regular invited speaker at international geology conferences. Scott is the recipient of the Gibb Maitland Medal for 2012. The Gibb Maitland Medal is awarded by the Geological Society of Australia – Western Australia Division for substantial contributions to Western Australian geology.
