Abstract: Abstract Phanerozoic boninites record enrichments of U over Th, giving Th/U: 0.5–1.6, relative to intraoceanic island arc tholeiites (IAT) where Th/U averages 2.6. Uranium enrichment is attributed to incorporation of shallow, oxidized fluids, U-rich but… read more here.

DOI: 10.1111/bre.12585
Abstract: The Rosebank Field is located in the Faroe‐Shetland Basin and hosts hydrocarbons within siliciclastic sediments interlayered with volcanic packages of the Late Paleocene to Early Eocene aged Flett Formation. Within this study the volcanic sequences… read more here.
