High-MgO lavas associated to CFB as indicators of plume-related thermochemical effects: the case of ultra-titaniferous picrite-basalt from the Northern Ethiopian-Yemeni plateau [PDF]
A comprehensive petrological and geochemical dataset is reported in order to define the thermo-compositional characteristics of Ti (Fe)-enriched picrite-basalt lavas (HT2, TiO2 3-7 wt%), erupted close to the axial zone of the inferred Afar mantle plume ...

Icelandic analogs to Martian flood lavas [PDF]
, 2004 We report on new field observations from Icelandic lava flows that have the same surface morphology as many Martian flood lava flows. The Martian flood lavas are characterized by a platy-ridged surface morphology whose formation is not well understood ...

Geochemistry, Geophysics, GeosystemsLavas erupted in Continental Flood Basalt (CFB) provinces are not primary magmas; they are differentiated products that result from large volumes of melt migrating and stalling in the lithosphere prior to eruption, resulting in complex liquid lines of ...

The Spokane flood controversy [PDF]
An enormous plexus of proglacial channels that eroded into the loess and basalt of the Columbia Plateau, eastern Washington is studied. This channeled scabland contained erosional and depositional features that were unique among fluvial phenomena ...

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 (

Some volcanologic aspects of Columbia River basalt volcanism relevant to the extinction controversy [PDF]
The Columbia River Basalt Group is the youngest and most thoroughly studied flood-basalt province known; information about it should be relevant to questions about the possible relation of flood-basalt volcanism to mass extinctions. The group has a total

Testing the use of viscous remanent magnetisation to date flood events [PDF]
, 2015 © 2015 Muxworthy, Williams and Heslop. Using erratics associated with large flood events, this paper assesses whether their viscous remanent magnetisation (VRM) can be used to date the flood events.

Flood Basalts and Lunar Petrogenesis [PDF]
Journal of Petrology, 2000 aspects. The expertise of Keith Cox would have been valuable in their interpretation. data were challenging this simplified view. Data for Hawaiian tholeiitic OIB demonstrated that the common basalts were differentiated and that only the picrites could be primary magmas (Yoder & Tilley, 1962; O’Hara,
