The Paran�-Etendeka flood volcanic event produced ∼1.5 x 106 cubic kilometers of volcanic rocks, ranging from basalts to rhyolites, before the separation of South America and Africa during the Cretaceous period. New 40Ar/39Ar data combined with earlier paleomagnetic results indicate that Paran� flood volcanism in southern Brazil began at 133 � 1 million years ago and lasted less than 1 million years. The implied mean eruption rate on the order of 1.5 cubic kilometers per year is consistent with…

A brief Oligocene period of flood volcanism in Yemen: implications for the duration and rate of continental flood volcanism at the Afro-Arabian triple junction
40Ar39Ar dating of mineral separates and whole-rock (WR) samples has established that basaltic continental flood volcanism (CFV) began between 30.9 and 29.2 Ma in northwestern and southwestern Yemen,…
The onset of flood basalt volcanism, Northern Paraná Basin, Brazil: A precise U–Pb baddeleyite/zircon age for a Chapecó-type dacite
Abstract We report the first U–Pb baddeleyite/zircon date for a felsic volcanic rock from the Parana Large Igneous Province in south Brazil. The new date of 134.3 ± 0.8 Ma for a hypocrystalline…
3-D, 40Ar? 39Ar geochronology in the Paran continental flood basalt province
New 40Ar39Ar analyses of borehole samples from the Parana-Etendeka continental flood basalt province provide critical evidence of eruption rates in unexposed regions. When combined with surface…
A short interval of Jurassic continental flood basalt volcanism in Antarctica as demonstrated by 40Ar39Ar geochronology
A continental flood basalt province, the Ferrar Group (Kirkpatrick Basalt and Ferrar Dolerite), crops out along 3000 km of the Transantarctic Mountains in Antarctica and is temporally related to the…
Post-rift regional volcanism in southern Santos Basin and the uplift of the adjacent South American coastal range
Abstract The Serra do Mar coastal mountain range plays a crucial role in the sedimentary budget of both the South American continent and its adjacent Atlantic margin. This 1500-km range began to rise…
Arc-rift transition volcanism in the Puertecitos Volcanic Province, northeastern Baja California, Mexico
The Neogene Puertecitos Volcanic Province of northeastern Baja California records a transition from arc-related volcanic activity to rift volcanism associated with opening of the Gulf of California.…
The hydrocarbon potential of the deep offshore along the Argentine volcanic rifted margin : a numerical simulation
In the Late Jurassic/Early Cretaceous, continental break-up of Gondwana led to the opening and northward propagating of the South Atlantic. Since 135Ma, the Paraná/Etendeka continental flood basalts…
Flood basalts, continental breakup and the dispersal of Gondwana: evidence for periodic migration of upwelling mantle flows (plumes)
The present study used igneous provinces, mainly continental flood volcanics or oceanic plateaus, at times associated with regional updoming, major rifting and continental breakup, together with its…

Mantle plumes and flood-basalt stratigraphy in the Paraná, South America
Geochemical studies of the Parana continental flood basalts in Brazil have led to the recognition of distinct magma types, which have been used to infer the internal stratigraphy of the lava pile.…
Rapid Eruption of the Siberian Traps Flood Basalts at the Permo-Triassic Boundary
TLDR
Laser-heating 40Ar/39Ar data indicate that inception of Siberian Traps volcanism coincided with a profound faunal mass extinction at the Permo-Triassic boundary 249 � 4 million years ago; these data thus leave open the question of a genetic relation between the two events.
Flood Basalt Volcanism During the Past 250 Million Years
TLDR
There were 11 distinct episodes of major continental flood basalt volcanism during the past 250 million years, and the initiation dates of the episodes are close to the estimated dates of mass extinctions of marine organisms.
Magmatism at rift zones: The generation of volcanic continental margins and flood basalts
When continents rift to form new ocean basins, the rifting is sometimes accompanied by massive igneous activity. We show that the production of magmatically active rifted margins and the effusion of…
Deccan traps mantle degassing in the terminal Cretaceous marine extinctions
Mantle degassing continually releases gases onto the earth's surface. Over geologically long time intervals, a general equilibrium probably exists between mantle CO2 release and uptake by surficial…
Plume-Generated Triple Junctions: Key Indicators in Applying Plate Tectonics to Old Rocks
Continental lithosphere-especially where stationary with respect to mantle plumes-is marked by plume-generated uplifts typically crested by volcanoes that rupture in three rifts at angles of about…
Implications of mantle plume structure for the evolution of flood basalts
Morgan [1,2] suggested that continental flood basalts appear as the first volcanic expression of new mantle plumes. Experimental studies in viscous liquids have shown that new, or "starting", plumes…
Flood Basalts and Hot-Spot Tracks: Plume Heads and Tails
TLDR
Continental flood basalt eruptions have resulted in sudden and massive accumulations of basaltic lavas in excess of any contemporary volcanic processes, thought to result from deep mantle plumes.
The Cretaceous-Tertiary Transition
TLDR
It seems more likely that an explanation for the changes during the Cretaceous-Tertiary transition will come from continued examination of the great variety of terrestrial events that took place at that time, including extensive volcanism, major regression of the sea from the land, geochemical changes, and paleoclimatic and paleoceanographic changes.
Mantle Plumes and Continental Tectonics
Mantle plumes and plate tectonics, the result of two distinct modes of convection within the Earth, operate largely independently. Although plumes are secondary in terms of heat transport, they have…
