Regional study of the Archean to Proterozoic crust at the Sudbury Neutrino Observatory (SNO+), Ontario: Predicting the geoneutrino flux

open access: yes, 2014
The SNO+ detector, a new kiloton scale liquid scintillator detector capable of recording geoneutrino events, will define the strength of the Earth radiogenic heat.

Coeval Early Ediacaran Breakup of Amazonia, Baltica, and Laurentia: Evidence From Micro‐Baddeleyite Dating of Dykes From the Novillo Canyon, Mexico

open access: yesGeophysical Research Letters, 2019
Final Rodinia supercontinent breakup during the early Ediacaran is recorded by mafic dyke swarms in Baltica and Laurentia, but corresponding dykes have been elusive for Amazonia, the third craton involved.

Contrasting stress fields on correlating margins of the South Atlantic [PDF]

open access: yes, 2015
The “passiveness” of passive continental margins across the globe is currently under debate since several studies have shown that these margins may experience a variety of stress states and undergo significant vertical movement post-breakup.

Prolonged plume volcanism in the Caribbean Large Igneous Province: New insights from Curaçao and Haiti

open access: yesGeochemistry, Geophysics, Geosystems, 2013
We present 36 new 40Ar‐39Ar incremental heating age determinations from the Caribbean Large Igneous Province (CLIP) providing evidence for extended periods of volcanic activity and suggest a new tectonomagmatic model for the province's timing and ...

Tectonic overview of the West Gondwana margin [PDF]

open access: yes, 2008
The oceanic southern margin of Gondwana, from southern South America through South Africa, West Antarctica, New Zealand (in its pre break-up position), and Victoria Land to Eastern Australia is one of the longest and longest-lived active continental ...

Large igneous provinces and silicic large igneous provinces: Progress in our understanding over the last 25 years [PDF]

open access: yesGeological Society of America Bulletin, 2013
Large Igneous Provinces are exceptional intraplate igneous events throughout Earth’s history. Their significance and potential global impact is related to the total volume of magma intruded and released during these geologically brief events (peak eruptions are often within 1-5 Myrs duration) where millions to tens of millions of cubic kilometers of ...

Silicic Large Igneous Provinces

open access: yesEpisodes, 2007
Large Igneous Provinces (LIPs) are the end-product of huge additions of magma to the continental crust both at the surface and at depth. Since the first categorisation of LIPs by Coffin & Eldholm (1994), it has been recognised that LIPs are more varied in form, age and character, and this includes the recognition of Silicic LIPs.

Mantle Potential Temperature Estimates and Primary Melt Compositions of the Low-Ti Emeishan Flood Basalt

open access: yesFrontiers in Earth Science, 2018
The Late Permian Emeishan large igneous province (ELIP) is considered to be one of the best examples of a mantle plume derived large igneous province. One of the primary observations that favor a mantle plume regime is the presence of ultramafic volcanic
