Overview

Synchrotron X-ray Fluorescence Microscopy (XFM) provides exceptionally detailed, large multi-element microchemical maps of thin rock specimens. Together with conventional optical and electron-beam imaging methods, XFM maps permit novel insights into coupled mass transfer processes at the grain scale controlling important Earth processes such as earthquake formation, volcanism, reactive fluid flow, and CO2-sequestration.

However, to this date, most scientific work using XFM is mostly qualitative and does not make full use of the statistical information that can be obtained from the data. This project aims to develop a simple workflow for characterising XFM maps of rocks with spatial statistical methods. This workflow will be developed in a simple high-level programming language (MATLAB, R, or Python) and applied to new data from the Australian Synchrotron.

Research activities

The successful candidate will:

  1. Review existing approaches to spatial statistics
  2. identify the most suitable algorithm for hypothesis testing applicbale to XFM maps
  3. implement these algorithms in a high-level code
  4. test the code on new XFM data from the Australian Synchrotron.

Outcomes

  • A new set of codes for spatial statistical analysis of XFM maps
  • the core of a journal article communicating the new methodology.

Skills and experience

  • Basic coding
  • basic statistics
  • basic image analysis
  • interest in chemistry.
