Presidential Address To The Mineralogical Society Of Amrica, Boston, November 6, 2001: Some Precambrian Banded Iron-Formations (BiIFs) From Around The World: Their Age, Geologic Setting, Mineralogy, Metamorphism, Geochemistry, And Origin
Abstract Banded iron-formations (BIFs) occur in the Precambrian geologic record over a wide time span. Beginning at 3.8 Ga (Isua, West Greenland), they are part of Archean cratons and range in age

Old sedimentary rocks record the history of oxygen in the form of redox-sensitive chemical species such as iron, uranium or cerium ions, and mass-independent fractionation of sulphur isotopes. These
Oxygenation of the Mesoproterozoic ocean and the evolution of complex eukaryotes
The Mesoproterozoic era (1,600–1,000 million years ago (Ma)) has long been considered a period of relative environmental stasis, with persistently low levels of atmospheric oxygen. There remains much
A 4463 Ma apparent zircon age from the Jack Hills (Western Australia) resulting from ancient Pb mobilization
Hadean (≥4.0 Ga) zircon grains provide the only direct record of the first half-billion years of Earth’s history. Determining accurate and precise crystallization ages of these ancient zircons is a
A Palaeoproterozoic tectono-magmatic lull as a potential trigger for the supercontinent cycle
The geologic record exhibits periods of active and quiescent geologic processes, including magmatism, metamorphism and mineralization. This apparent episodicity has been ascribed either to bias in
Supercontinents and the case for Pannotia
Abstract Disagreement about the existence of the late Neoproterozoic supercontinent Pannotia highlights the limitation of defining supercontinents simply on the basis of size, which, for pre-Pangaean
