Notes & References [1000] So called `komatiite' (discovered in 1969), basalt-like rocks are distinguished by containing magnesium oxide concentrations between 18-30 wt%, as compared to 10-15 wt% for other basaltic rocks. They also exhibit in places distinctive olivine crystals that have interlocking spines described as "spinifex" texture. The greatest number of komatiite occurs in the Archaean. Fewer examples are found in the Proterozoic and only 3 in the Phanerozoic (the most recent is assigned a Cretaceous age). Boninite is also a high magnesium rock.
