Lithogeochemistry and origin of the komatiites from Mundonguara mine …
Based on these trace element ratios, the komatiites from the Manica greenstone belt are most likely affected by crustal contamination, particularly through the addition of Th to the magma, similar to what is described from the Belingwe greenstone belt (Dirks et al., 2015). This contamination may also have contributed to the negative Nb ...
