Metamorphic olivine in pictritic metavolcanics from southern Finland

Metamorphic olivine occurs in magnesian (>18 wt.% MgO) medium-Ti (TiO2 = 1.0‒2.0 wt.%), mafic to ultramafic metapicritic rocks in the Early Proterozoic Svecofennian domain of Southern Finland. Relatively Fe2SiO4-rich porphyroblastic olivines formed in those rocks through decomposition of Fe-Mg ch...
