Rapid Formation of the Ellice and Osbourn Basins and Ontong Java Nui Breakup Kinematics

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Breakup of the proposed greater Ontong Java Nui large igneous province during the Cretaceous Normal Superchron can be constrained by the opening of the Ellice Basin (EB) separating the Ontong Java and Manihiki Plateaus and the Osbourn Basin separating ...

From Nouns and Adjectives to Verbs: Base Effects on the Grammatical Behaviour of Denominal Verbs in Ancient Greek1

open access: yesTransactions of the Philological Society, EarlyView.
Abstract This paper investigates the role of semantic features of noun and adjective bases in determining the grammatical behaviour of Ancient Greek denominal and deadjectival verbs in *‐ye/o‐. The paper adopts a lexicalist framework (Rappaport Hovav & Levin 1998) and examines how the event schema, actionality, telicity and voice of derived verbs are ...

MORB differentiation: In situ crystallization in replenished-tapped magma chambers [PDF]

open access: yes, 2015
The differentiation of mid-ocean ridge basalt (MORB) is investigated with a focus on intermediate- to fast-spreading ridges and two recently proposed differentiation mechanisms: (i) differentiation in replenished-tapped-crystallizing (RTX) magma chambers,

Why is the remanent magnetic intensity of Cretaceous MORB so much higher than that of mid to late Cenozoic MORB? [PDF]

open access: yesGeosphere, 2005
The fact that the natural remanent magnetization (NRM) intensity of mid-oceanicridge basalt (MORB) samples shows systematic variations as a function of age has long been recognized: maximum as well as average intensities are generally high for very young samples, falling off rather rapidly to less than half the recent values in samples between 10 and ...

Geochemical characteristics of back-arc basin lower crust and upper mantle at final spreading stage of Shikoku Basin: an example of Mado Megamullion

open access: yesProgress in Earth and Planetary Science, 2021
This paper explores the evolutional process of back-arc basin (BAB) magma system at final spreading stage of extinct BAB, Shikoku Basin (Philippine Sea) and assesses its tectonic evolution using a newly discovered oceanic core complex, the Mado ...

The heterogeneity of the Mexican lithospheric mantle: Clues from noble gas and CO2 isotopes in fluid inclusions

open access: yesFrontiers in Earth Science, 2022
The abundance of mantle-derived rocks and lavas, in combination with its tectonic evolution, render Mexico a perfect laboratory to investigate the chemical and the isotopic heterogeneity of the lithospheric mantle.
