Previous researchers associated the Deccan continental flood basalt (CFB) with the Réunion hot spot (), a center of long-term magmatism presently located under the volcanic edifices of Réunion Island that appears to be fed by anomalously hot underlying mantle ().The interpretation of the mantle dynamic processes that resulted in the eruption of the Deccan Traps has been mainly based on filexlib.

Recent attempts to establish the eruptive history of the Deccan Traps large igneous province have used both U-Pb (Schoene et al., 2019) and 40Ar/39Ar (Sprain et al., 2019) geochronology. Both of these studies report dates with high precision and unprecedented coverage for a large igneous province, and agree that the main phase of eruptions began near the C30n-C29r magnetic reversal argue that "Phase 2 of the Deccan traps begins somewhere in the top of MagnetoChron 30N". However, Smit et al. are not aware that high-precision U-Pb dating of Deccan phase 2 accurately places the onset ~250 k.y. before the KPg boundary (Schoene et al., 2015) and correlative with the base of magnetochron C29r (Chenet et al., 2007).

A set of whole rock lava flows and dykes from the western part of Deccan Traps, Western India, was analyzed for oxygen isotope ratios. δ18O stratigraphy of the upper formations in the Mahabaleshwar section of the Western Ghats area can be correlated with the Sr- and Nd-isotopic stratigraphy, in that increasing δ18O is associated with increasing initial 87Sr/86Sr and decreasing initial ɛNd.
The flood basalt province known as the Deccan Traps is located on the Deccan Plateau in west-central India and is one of the largest volcanic provinces in the world. The Deccan Plateau consists of more than 2000 m-thick succession of flat-lying basalt lava flows and covers an area of nearly 500 000 km 2 .
Abstract. The Indian subcontinent is blanketed with the remnants of at least five continental flood basalt provinces ranging in age from the Middle Proterozoic to the Late Cretaceous-Early Tertiary. Not surprisingly, the youngest of these, the Deccan plateau (derived from a Sanskrit word meaning "south" or "southern") is by far the best
We compare two published U-Pb and 40 Ar / 39 Ar geochronologic datasets to produce eruption rate models for the Deccan Traps large igneous province. Applying the same approach to each dataset, the resulting models agree well, but the higher-precision U-Pb dataset results in a more detailed eruption model than the lower-precision 40 Ar / 39 Ar data.
The compact and abrasion resistant traps are locally used as road metal, railway ballast and building stone. Kankar from which lime is made occurs at numerous places along the foot hills and in the nalas all over the district.. Groundwater - Usually in a trap covered country the intertrappean sedimentary beds serve as good aquifers. But the middle traps being devoid of such beds, water occurs
Gerta Keller (born 7 March 1945) is a geologist and paleontologist who contests the Alvarez hypothesis that the impact of the Chicxulub impactor, or another large celestial body, directly caused the Cretaceous-Paleogene extinction event.Keller maintains that such an impact predates the mass extinction and that Deccan volcanism and its environmental consequences were the most likely major
