Dr Maya Kamenetsky graduated from the Moscow State University in 1984. Since graduation, Maya has worked in experimental, petrographic and analytical laboratories in the State Institute of Glass, Moscow, and Institute of Experimental Mineralogy, Chernogolovka (Russian Federation), Centre d'etudes de Saclay/C.N.R.S., Saclay (France), Geology Department and Research School of Earth Sciences, Australian National University, Canberra (Australia), Max Planck Institute for Chemistry, Mainz (Germany) and Institute of Earth Sciences, the Hebrew University of Jerusalem (Israel). In 2006 she received her PhD from the University of Tasmania. Since then Maya has worked for Program 4 at CODES, using a scanning electron microscope (Quanta 600) for mineral liberation analysis (MLA).
Mineral Liberation Analyser
The MLA is a FEI Qanta 600 Scanning Electron Microscope and EDAX energy dispersive X-ray analysis system combined with a software suite written at the Julius Kruttschnitt Mineral Research Centre, University of Queensland (JKMRC).The software combines "back-scattered electron" (BSE) image of a sample and X-ray techniques for: accurate and efficient measurements. This technique can be used for quantitative mineralogical details for the sample (sample mineralogy, sizes of every particle and grain and mineral associations); and efficient detection of very minor (typically between 0.01 to 1.0 vol.%) and fine (sub-micron) minerals or components, such as gold.
Maya successfully adopts and applies the MLA analytical technique for ore characterisation, tracking trace element budgets (including gold, silver, U and REE-bearing minerals) in concentrates and uncrushed samples and for searching small mineral grains (perovskite, zircon, apatite, rutile and monazite) for isotope analyses. She trains and supervises research staff and PhD students in the use of MLA for different research tasks. Maya applies her expertise in melt and fluid inclusion, and experimental and analytical studies to the interpretation of petrological and geochemical issues of magma genesis, fractionation and evolution in different geodynamic settings: Kimberlites and Large Igneous Provinces (Baffin Island, Canada and Emeishan, China). She is also actively involved in the industry-funded project Setting, age and architecture of the Olympic Dam Au-Cu-U-deposit, South Australia.
