Constraining the Magmatic Plumbing System in a Zoned Continental Flood Basalt Province

Geochemistry, Geophysics, Geosystems, 2018
The geographic heterogeneities in lava composition observed in continental flood basalt provinces could provide a probe of material upwelling from the deep mantle and their length scales, but their utility is limited by uncertainties in the locus of ...

Terrestrial analogs and thermal models for Martian flood lavas [PDF]

, 2000
The recent flood lavas on Mars appear to have a characteristic “platy-ridged” surface morphology different from that inferred for most terrestrial continental flood basalt flows.

Workshop to develop deep-life continental scientific drilling projects [PDF]

Scientific Drilling, 2015
The International Continental Scientific Drilling Program (ICDP) has long espoused studies of deep subsurface life, and has targeted fundamental questions regarding subsurface life, including the following: "(1) What is the extent and diversity of deep ...

SIMS U-Pb, Sm-Nd isotope and geochemical study of an arkosite-amphibolite suite, Peräpohja Schist Belt: Evidence for ca. 1.98 Ga A-type felsic magmatism in northern Finland [PDF]

Bulletin of the Geological Society of Finland, 2005
In the northern and north-eastern part of the Perädpohja Schist Belt, northern Finland, an extensive supracrustal rock unit has been identified which is composed of alternating amphibolitic and arkositic components.

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

, 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.

Sedimentation record in the Konkan-Kerala Basin: implications for the evolution of the Western Ghats and the Western Indian passive margin [PDF]

, 2007
The Konkan and Kerala Basins constitute a major depocentre for sediment from the onshore hinterland of Western India and as such provide a valuable record of the timing and magnitude of Cenozoic denudation along the continental margin.

Application of palynological data to the chronology of the Palaeogene lava fields of the British Province: implications for magmatic stratigraphy [PDF]

, 1997
New high-precision ages, determined from palynomorph assemblages within intercalated sedimentary deposits, are presented for the Palaeogene lava fields (Skye, Mull and Antrim) of the British Province. These data reveal very rapid averaged eruption rates (

Changing Mantle Sources and the Effects of Crustal Passage on the Steens Basalt, SE Oregon: Chemical and Isotopic Constraints

Geochemistry, Geophysics, Geosystems, 2020
Continental flood basalts are more prone to compositional modification from passage through thicker and (or) more felsic crust in comparison to their oceanic counterparts.

Petrogenesis of the Adigrat basalts from the Oligocene Ethiopian flood basalt province in Tigrai, Northern Ethiopia

Scientific African
The Adigrat basalts are exposed along a prominent E-W extending ridge between Adigrat and Shire at the northern edge of the Ethiopian continental flood basalt province. They form up to twenty three individual lava flows with a total thickness of ∼ 1200 m.
