Petrographic, Geochemical, and Isotopic Constraints on the Provenance of the Early Proterozoic Chelmsford Formation, Sudbury Basin, Ontario
TL;DR: The early Proterozoic Chelmsford Formation, a coarse-grained turbidite unit in the Sudbury Basin, was deposited near the margin of the Superior Province craton at about the time of Penokean orogenesis as discussed by the authors.
Journal ArticleDOI
Contrasting conditions preceding MIS3 and MIS2 Heinrich events
Elsa Jullien,Francis E. Grousset,Sidney R. Hemming,Victoria L Peck,Ian Hall,Cédric Jeantet,Isabelle Billy +6 more
TL;DR: In this paper, an integrated multi-tracer study performed on piston cores recovered in the glacial ice-rafted detritus belt, stretching from Newfoundland to the Irish margin across the North Atlantic (40-55°N), in order to compare in detail the internal structure of each Heinrich event (HE).
Journal ArticleDOI
A 19 to 17 Ma amagmatic extension event at the Mid-Atlantic Ridge: Ultramafic mylonites from the Vema Lithospheric Section
Anna Cipriani,Enrico Bonatti,Enrico Bonatti,Monique Seyler,Hannes K. Brueckner,Hannes K. Brueckner,Daniele Brunelli,Luigi Dallai,Sidney R. Hemming,Marco Ligi,Luisa Ottolini,Brent D. Turrin,Brent D. Turrin +12 more
TL;DR: In this paper, strong deformed mylonitic peridotites were found at 14 contiguous sites within a ∼80 km stretch (∼4.7 Ma interval); they are dominant in a time interval of 1.4 Ma, from crustal ages of 16.8 to 18.2 Ma (mylonitic stretch).
Journal ArticleDOI
Age constraints on a Neogene tropical rainforest in China and its relation to the Middle Miocene Climatic Optimum
Daran Zheng,Daran Zheng,Gongle Shi,Sidney R. Hemming,Sidney R. Hemming,Haichun Zhang,Wei-Ming Wang,Bo Wang,Su-Chin Chang +8 more
TL;DR: Fotan Group fossils demonstrate that highly diverse tropical ecosystems existed during the early Neogene in southeastern China as mentioned in this paper and provide important constraints on the biogeographic history of the field area and paleographic models linking Asian and Indian biota.
Journal ArticleDOI
Paleointensity Record From the 2.7 Ga Stillwater Complex, Montana
TL;DR: In this article, the authors present results of modified Thellier paleointensity experiments on 441 core specimens, 114 of which pass strict reliability criteria, from 53 sites spanning most of the Banded Series rocks in the Stillwater Complex.
