Organic ligands and CO2 unlock the potential for energy relevant metals recovery and carbon mineralization from mafic rocks [PDF]
Scientific ReportsThe need to meet the rising demand for energy relevant metals (e.g., Fe, Mn, Al, Cr, Ni) motivates the development of sustainable chemical pathways to recover these metals from earth abundant and unconventional resources such as mafic rocks.

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links
Geophysical Monograph Series, Page 191-228., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The 1.88 Ga Kotalahti and Vammala nickel belts, Finland: Geochemistry of the mafic and ultramafic metavolcanic rocks [PDF]
Bulletin of the Geological Society of Finland, 2009 The mafic and ultramafic volcanic rocks within the Svecofennian (1.88 Ga) Kotalahti and Vammala Nickel Belts, Finland, are spatially associated and coeval with a suite of mineralized mafic-ultramafic intrusions.

Metamorphic olivine in pictritic metavolcanics from southern Finland [PDF]
Bulletin of the Geological Society of Finland, 1990 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.

The age of the ferropicritic volcanics and comagmatic Ni-bearing intrusions at Pechenga, Kola Peninsula, U.S.S.R. [PDF]
Bulletin of the Geological Society of Finland, 1990 Sm-Nd, Pb-Pb and U-Pb isotopic results are presented for samples from the Pilgujärvi Suite of the Pechenga Series. Whole rock samples and clinopyroxenes of ferropicritic volcanics yield a Sm-Nd isochron age of 1990 ± 66 Ma with εNd + 1.6 ± 0.4.
