Reappraisal of Duration and Eruptive Rates in Deccan Volcanic Province, India
Rapidly expanding geochronological, paleomagnetic and volcanological data of the Deccan Volcanic Province (DVP) has given new insights to the expansive knowledge on it that had been built up through
Evaluation of the four potential Cretaceous-Paleogene (K-Pg) boundaries in the Nanxiong Basin based on evidences from volcanic activity and paleoclimatic evolution
Determining the location of the Cretaceous-Paleogene (K-Pg) boundary in terrestrial strata is highly significant for studying the evolution of terrestrial ecosystems at the end of the Cretaceous
Evidence of biotic recovery through the Cretaceous/Palaeogene transition from the Mahadeo-Cherrapunji succession in the Meghalaya shelf, India
Earlier studies on the Mahadeo-Cherrapunji road (MCR) section have documented the Cretaceous-Palaeogene Boundary (KPB ca. ~ 66 Ma), but rare data exist on the Deccan volcanism induced KPB transition
The Magmatic Architecture of Continental Flood Basalts I: Observations From the Deccan Traps
Flood basalts are some of the largest magmatic events in Earth history, with intrusion and eruption of millions of km3 of basaltic magma over a short time period (∼1–5 Ma). A typical continental
Morphological types in the Deccan Volcanic Province, India: implications for emplacement dynamics of continental flood basalts
Abstract We review and compare morphologies from continental basaltic lavas, using examples from the Deccan Volcanic Province to compile their internal configurations and mutual associations and


A volcanic trigger for the Late Ordovician mass extinction? Mercury data from south China and Laurentia
The Late Ordovician mass extinction (LOME), one of the five largest Phanerozoic biodiversity depletions, occurred in two pulses associated with the expansion and contraction of ice sheets on Gondwana
Mercury anomalies and the timing of biotic recovery following the end-Triassic mass extinction
Hg isotopes display no significant mass independent fractionation within the extinction and depauperate intervals, consistent with a volcanic origin for the Hg, and indicate that significant biotic recovery did not begin until CAMP eruptions ceased.
Deccan volcanism linked to the Cretaceous-Tertiary boundary mass extinction: New evidence from ONGC wells in the Krishna-Godavari Basin
A scientific challenge is to assess the role of Deccan volcanism in the Cretaceous-Tertiary boundary (KTB) mass extinction. Here we report on the stratigraphy and biologic effects of Deccan volcanism
Does large igneous province volcanism always perturb the mercury cycle? Comparing the records of Oceanic Anoxic Event 2 and the end-Cretaceous to other Mesozoic events
Mercury (Hg) is increasingly being used as a sedimentary tracer of Large Igneous Province (LIP) volcanism, and supports hypotheses of a coincidence between the formation of several LIPs and episodes
Mercury evidence for pulsed volcanism during the end-Triassic mass extinction
Pulsatory volcanism, and associated perturbations in the ocean–atmosphere system, likely had profound implications for the rate and magnitude of the end-Triassic mass extinction and subsequent biotic recovery.
State shift in Deccan volcanism at the Cretaceous-Paleogene boundary, possibly induced by impact
High-precision dating of Deccan Traps volcanic units suggests an increase in volcanism associated with the Chicxulub impact, which suggests postextinction recovery of marine ecosystems was probably suppressed until after the accelerated volcanism waned.
