Dr Petrus Le Roux

Chief Research Officer

Igneous petrology, archaeometry



My geological research interest is in the use of light elements (Li, B) in igneous rocks, especially subduction zone and oceanic basalts, to understand the geochemical cycling of material, as well as the possible shallow-level magma assimilation, contamination and/or degassing systematics beneath mid-ocean ridges.

The development of new MC-ICP-MS isotopic analytical methods and novel applications, especially in situ Sr, Pb, Hf, B or Li isotope analysis using laser ablation.

I have a significant multi-disciplinary research focus on the use of Sr (and Pb) isotopes in palaeoanthropological, palaeontological and biological studies to place constraints on origins, landscape use or migration patterns of plants, hominins, early human societies, extinct animals or dinosaurs.
