Journal ArticleDOI
The Emperor Seamounts: Southward Motion of the Hawaiian Hotspot Plume in Earth's Mantle
John A. Tarduno,Robert A. Duncan,David W. Scholl,Rory D. Cottrell,Bernhard Steinberger,Thorvaldur Thordarson,Bryan C. Kerr,Clive R. Neal,Frederick A. Frey,Masayuki Torii,Claire Carvallo +10 more
TL;DR: P paleomagnetic and radiometric age data from samples recovered by ocean drilling define an age-progressive paleolatitude history, indicating that the Emperor Seamount trend was principally formed by the rapid motion of the Hawaiian hotspot plume during Late Cretaceous to early-Tertiary times.
Journal ArticleDOI
Geodynamo, Solar Wind, and Magnetopause 3.4 to 3.45 Billion Years Ago
John A. Tarduno,Rory D. Cottrell,Michael K. Watkeys,Axel Hofmann,Pavel V. Doubrovine,Pavel V. Doubrovine,Eric E. Mamajek,Dunji Liu,David G. Sibeck,Levi P. Neukirch,Yoichi Usui,Yoichi Usui +11 more
TL;DR: Analysis of ancient silicate crystals indicates that Earth’s magnetic field existed 3.40 to 3.45 billion years ago, pushing back the oldest record of geomagnetic field strength by 200 million years.
Journal ArticleDOI
Rapid formation of Ontong Java Plateau by Aptian mantle plume volcanism
John A. Tarduno,William V. Sliter,Loren W. Kroenke,M. Leckie,H. Mayer,John J. Mahoney,Robert J. Musgrave,Michael Storey,Edward L. Winterer +8 more
TL;DR: Formation of the OJP may have led to a rise in sea level that induced global oceanic anoxia and carbon dioxide emissions likely contributed to the mid-Cretaceous greenhouse climate but did not provoke major biologic extinctions.
Journal ArticleDOI
Evidence for Extreme Climatic Warmth from Late Cretaceous Arctic Vertebrates
John A. Tarduno,D. B. Brinkman,Paul R. Renne,Rory D. Cottrell,Howie D. Scher,Paterno R. Castillo +5 more
TL;DR: A Late Cretaceous vertebrate assemblage from the high Canadian Arctic implies that polar climates were warm rather than near freezing, and magmatism at six large igneous provinces at this time suggests that volcanic carbon dioxide emissions helped cause the global warmth.
Journal ArticleDOI
A Hadean to Paleoarchean geodynamo recorded by single zircon crystals
TL;DR: Full-vector paleointensity measurements of Archean to Hadean zircons bearing magnetic inclusions from the Jack Hills conglomerate are reported to reconstruct the early geodynamo history and imply that early atmospheric evolution on both Earth and Mars was regulated by dynamo behavior.
