    Volcanic Degassing (2003)
    London : The Geological Society
    Details
    Description / Table of Contents: Humans have long marvelled at (and feared) the odorous and colourful manifestations of volcanic emissions, and, in some cases, have harnessed them for their economic value. The degassing process responsible for these phenomena is now understood to be one of the key factors influencing the timing and nature of volcanic eruptions. Moreover the surface emissions of these volatiles can have profound effects on the atmospheric and terrestrial environment, and climate. Even more fundamental are the relationships between the history of planetary outgassing, differentiation of the Earth’s interior, chemistry of the atmosphere and hydrosphere, and the origin and evolution of life. This book provides a compilation of 23 papers that investigate the behaviour of volatiles in magma, the feedbacks between degassing and magma dynamics, and the composition, flux, and environmental, atmospheric and climatic impacts of volcanic gas emissions.

    High-resolution size distributions and emission fluxes of trace elements from Masaya volcano, Nicaragua (2012)
    Wiley
    Details
    Publication Date: 2012-08-25
    Description: Active volcanoes are significant natural sources of trace elements to the atmosphere yet the processes of emission and the impacts of deposition into terrestrial and aquatic environments remain poorly understood. The varying contributions of volatile degassing and magma ejection (i.e., spattering, spraying, extrusion and fragmentation) to the emission of trace elements from Masaya volcano (Nicaragua) are investigated through measurement of high-resolution trace element size distributions using cascade impactors in 2009 and 2010. The volatile elements (e.g., As, Cd, Tl, Cu, Pb, Zn) are strongly correlated across the size distribution and exist in the plume primarily as fine sulfate (0.6 μm diameter) with lesser amounts transported as coarse sulfates (3.5 μm diameter) and coarse chlorides (11 μm diameter). These results suggest that trace elements released from the magma as chlorides react rapidly with H2SO4 in the plume to form sulfates. In contrast, the non-volatile elements (e.g., alkali earth and rare earth) exist primarily as particles in the 1–10 μm range and show no correlation with sulfate, chloride or the volatile elements, suggesting that they are emitted primarily by magma ejection. Trace element emission fluxes from Masaya in 2010 were estimated using filter pack measurements, with emissions of Cu, Zn, As, Tl, Rb and Cd each in excess of 10 kg d−1. These emission fluxes are similar to those measured in 2000–2001 suggesting notable decadal stability in the emission of trace elements from Masaya.

    Quantifying Asthenospheric and Lithospheric Controls on Mafic Magmatism across North Africa (2019)
    Wiley
    Details
    Publication Date: 2019
    Description: Abstract African basin‐and‐swell morphology is often attributed to the planform of sub‐plate mantle convection. Across North Africa, the coincidence of Neogene and Quaternary (i.e. 〈23 Ma) magmatism, topographic swells, long wavelength gravity anomalies, and slow shear wave velocity anomalies within the asthenosphere provides observational constraints for this hypothesis. Admittance analysis of topographic and gravity fields corroborates the existence of sub‐plate support. To investigate quantitative relationships between intraplate magmatism, shear wave velocity, and asthenospheric temperature, we collected and analyzed a suite of 224 lava samples from Tibesti, Jabal Eghei, Haruj, Sawda/Hasawinah and Gharyan volcanic centers of Libya and Chad. Forward and inverse modeling of major, trace, and Rare Earth elements were used for thermobarometric studies and to determine melt fraction as a function of depth. At each center, mafic magmatism is modeled by assuming adiabatic decompression of dry peridotite with asthenospheric potential temperatures of 1300–1360°C. Surprisingly, the highest temperatures are associated with the low‐lying Haruj volcanic center rather than with the more prominent Tibesti swell. Our results are consistent with earthquake tomographic models which show that the slowest shear wave anomalies within the upper mantle occur directly beneath the Haruj center. This inference is corroborated by converting observed velocities into potential temperatures, which are in good agreement with those determined by geochemical inverse modeling. Our results suggest that North African volcanic swells are primarily generated by thermal anomalies located beneath thinned lithosphere.

    Middle Paleolithic assemblages from the Indian subcontinent before and after the Toba super-eruption (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-07-07
    Description: The Youngest Toba Tuff (YTT) eruption, which occurred in Indonesia 74,000 years ago, is one of Earth's largest known volcanic events. The effect of the YTT eruption on existing populations of humans, and accordingly on the course of human evolution, is debated. Here we associate the YTT with archaeological assemblages at Jwalapuram, in the Jurreru River valley of southern India. Broad continuity of Middle Paleolithic technology across the YTT event suggests that hominins persisted regionally across this major eruptive event.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Petraglia, Michael -- Korisettar, Ravi -- Boivin, Nicole -- Clarkson, Christopher -- Ditchfield, Peter -- Jones, Sacha -- Koshy, Jinu -- Lahr, Marta Mirazon -- Oppenheimer, Clive -- Pyle, David -- Roberts, Richard -- Schwenninger, Jean-Luc -- Arnold, Lee -- White, Kevin -- New York, N.Y. -- Science. 2007 Jul 6;317(5834):114-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Leverhulme Centre for Human Evolutionary Studies, University of Cambridge, Cambridge CB2 1QH, UK. m.petraglia@human-evol.cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17615356" target="_blank"〉PubMed〈/a〉

    Molecular Phylogeography of a Human Autosomal Skin Color Locus Under Natural Selection (2013)
    Genetics Society of America (GSA)
    Details
    Publication Date: 2013-11-09
    Description: Divergent natural selection caused by differences in solar exposure has resulted in distinctive variations in skin color between human populations. The derived light skin color allele of the SLC24A5 gene, A111T , predominates in populations of Western Eurasian ancestry. To gain insight into when and where this mutation arose, we defined common haplotypes in the genomic region around SLC24A5 across diverse human populations and deduced phylogenetic relationships between them. Virtually all chromosomes carrying the A111T allele share a single 78-kb haplotype that we call C11, indicating that all instances of this mutation in human populations share a common origin. The C11 haplotype was most likely created by a crossover between two haplotypes, followed by the A111T mutation. The two parental precursor haplotypes are found from East Asia to the Americas but are nearly absent in Africa. The distributions of C11 and its parental haplotypes make it most likely that these two last steps occurred between the Middle East and the Indian subcontinent, with the A111T mutation occurring after the split between the ancestors of Europeans and East Asians.

    A probabilistic assessment of sea level variations within the last interglacial stage (2013)
    Oxford University Press
    Details
    Publication Date: 2013-04-11
    Description: The last interglacial stage (LIG; ca . 130–115 ka) provides a relatively recent example of a world with both poles characterized by greater-than-Holocene temperatures similar to those expected later in this century under a range of greenhouse gas emission scenarios. Previous analyses inferred that LIG mean global sea level (GSL) peaked 6–9 m higher than today. Here, we extend our earlier work to perform a probabilistic assessment of sea level variability within the LIG highstand. Using the terminology for probability employed in the Intergovernmental Panel on Climate Change assessment reports, we find it extremely likely (95 per cent probability) that the palaeo-sea level record allows resolution of at least two intra-LIG sea level peaks and likely (67 per cent probability) that the magnitude of low-to-high swings exceeded 4 m. Moreover, it is likely that there was a period during the LIG in which GSL rose at a 1000-yr average rate exceeding 3 m kyr –1 , but unlikely (33 per cent probability) that the rate exceeded 7 m kyr –1 and extremely unlikely (5 per cent probability) that it exceeded 11 m kyr –1 . These rate estimates can provide insight into rates of Greenland and/or Antarctic melt under climate conditions partially analogous to those expected in the 21st century.

    FTIR remote sensing of fractional magma degassing at Mount Etna, Sicily (2003)
    In:  Geological Society Special Publication 213: 281-293.
    Details
    Publication Date: 2003-01-01
    Description: The chemical composition of volcanic gas emissions from each of the four summit craters of Mount Etna was measured remotely in May 2001, using a Fourier transform infrared (FTIR) spectrometer operated on the upper flanks of the volcano. The results reveal constant HCl/HF ratio but distinct SO2/HCl and SO2/HF ratios in the emitted gases, which, in the light of melt inclusion data for Etna basalts, can be interpreted in terms of escape of gases from partially, and variably, degassed magma at different depths beneath the summit. Gases released from the three main summit craters (Bocca Nuova, Voragine, and Northeast) had an identical composition, controlled by bulk degassing of a single magma body that had previously lost c. 25% of its original sulphur. The similar gas composition at all three main craters suggests that these are connected to a central conduit system that branches at relatively shallow depth. Measurements of the bulk volcanic plume on the same day, c. 7 km downwind, show that degassing from these craters dominated the total gas output of the volcano, and that no significant chemical evolution occurred within the plume over a time-scale of c. 12 min. Weaker gas emissions from the Southeast crater were comparatively depleted in SO2 (SO2/HCl and SO2/HF ratios a factor of two lower), implying that this crater is fed either by a separate conduit or by a branch of the central conduit whose geometry favours solubility-controlled volatile fractionation. Still lower SO2/HCl and SO2/HF ratios measured for residual degassing of a lava flow erupted from the Southeast crater verify the lower solubility and earlier escape of sulphur compared to halogens at Etna. Fractional magma degassing is also implied by strong chemical contrasts between the bulk volcanic plume and fissure gas emissions measured during the July-August 2001 flank eruption. These results highlight the ability of FTIR spectrometry to detect fine spatial and temporal variations in magma degassing processes, and thereby constrain models of shallow plumbing systems.

    Compositional variation in tropospheric volcanic gas plumes: evidence from ground-based remote sensing (2003)
    In:  Geological Society Special Publication 213: 349-369.
    Details
    Publication Date: 2003-01-01
    Description: Remotely sensed measurements of volcanic plumes have been undertaken for 30 years with instruments such as the correlation spectrometer, and more recently, open-path Fourier transform infrared (OP-FTIR) spectrometers. Observations are typically made several kilometres from the source, by which time chemical reactions may have occurred in the plume, overprinting the source composition and flux. Volcanological interpretations of such data therefore demand an understanding of the atmospheric processes initiated as gases leave the volcanic vent. Ground-based remote sensing techniques offer the temporal resolution, repeatability and quantitative analysis necessary for investigation of these processes. Here we report OP-FTIR spectroscopic measurements of gas emissions from Masaya Volcano, Nicaragua, between 1998 and 2001, and examine the influence of atmospheric processes on its tropospheric plume. Comparisons of observations made at the summit and down-wind, and in different measurement modes confirm that tropospheric processes and local meteorology have only minor impact on gas composition after the plume has left the crater. This study demonstrates that plume monitoring downwind provides a reliable proxy for at-crater sampling, and that volcanological information content is not obscured by the intervening transport. From February 1998 to May 2000, Masaya's plume composition was strikingly stable and characterized by SO2/HCl and HCl/HF molar ratios of 1.6 and 5.0, respectively. Departures from this stable background composition are likely to signify changes in the volcanic system or degassing regime, as identified in April-May 2001.
