The Palaeoproterozoic positive excursion of δ 13C carb is now considered as three positive
shifts of δ 13C carb separated by returns to 0‰, which all occurred between 2.40 and 2.06 …

The first significant buildup in atmospheric oxygen, the Great Oxidation Event (GOE), began
in the early Paleoproterozoic in association with global glaciations and continued until the …

Compared with present-day global plate tectonics, Archaean and Palaeoproterozoic plate
tectonics may have involved faster moving, hotter plates that accumulated less sediment and …

The inability to resolve the exact temporal relationship between two pivotal events in Earth
history, the Paleoproterozoic Great Oxidation Event (GOE) and the first “snowball Earth” …

We have compiled a record of the geochronology of mantle plume activity between 3.8 and
1.6 Ga. Over this time period, the ages of komatiites, and those of global plumes, correlate …

Recent geological studies have provided new concepts concerning the timing of the final
break-up of the Archaean craton. Age data on detrital zircons from sedimentary rocks in …

A tectonic model is proposed for the Palaeoproterozoic Lapland-Kola orogen (LKO) in the
northern Fennoscandian Shield. Although long regarded as an Archaean craton, integrated …

We identify 304 mafic magmatic events ranging in age from ca. 3500 Ma to the present and
assess their potential for linkage to the arrival of mantle-plume heads. For each, we …

Radiometric dating, including numerous high-precision U-Pb baddeleyite and zircon ages,
of Paleoproterozoic flood basalts, dike swarms, and layered mafic intrusions worldwide …

New isotope and trace element data are presented for komatiitic basalts and a related
peridotite Vinela Dike from the large Vetreny Belt in the southeastern Baltic Shield. The MgO …
