Origin of Paleoproterozoic Komatiites at Jeesiörova ... DeepDyve
Komatiites from the ∼2 Ga Jeesiörova area in Finnish Lapland have subchondritic Al2O3/TiO2 ratios like those in Aldepleted komatiites from Barberton, South Africa. They are distinct in that their Al abundances are higher than those of the Aldepleted rocks and similar to levels in Alundepleted komatiites. Moderately incompatible elements such as Ti, Zr, Eu, and Gd are enriched. Neither ...

Komatiite an overview | ScienceDirect Topics
The simple description is that "komatiite" is an ultramafic volcanic rock (Arndt and Nisbet, 1982b) with a lower limit of 18% MgO separating komatiites from picrites, ankaramites or magnesian basalts. Implicit in the definition of komatiite is the notion, difficult to prove, that komatiites crystallise from liquids that contained > 18% MgO ...
