  • Disparate impacts of the Eldgjá and Laki flood-lava eruptions

    Open AccessConner A G Morison, Clive Oppenheimer et al.ARTICLEThe Holocene2024References: 10

    The Eldgjá eruption of ~ 939 AD is recognised as the largest in Iceland since Settlement, and ranks among the largest late-Holocene volcanic episodes on Earth. It disgorged > 21.0 km 3 (Dense Rock Equivalent) of magma as lava flows (~ 19.7 km 3 ) and tephra deposits (> 1.3 km 3 DRE), comprising alternating phreatomagmatic (wet) and magmatic (dry) explosive phases. Tephra deposits up to four metres thick buried proximal areas, and extreme quantiti…

  • Enhancing Radiocarbon Chronologies of Colonization

    Open AccessMagdalena M E Bunbury, Rachel Wood et al.ARTICLERadiocarbon2019Cited by: 7References: 45

    Accurately dating when people first colonized new areas is vital for understanding the pace of past cultural and environmental changes, including questions of mobility, human impacts and human responses to climate change. Establishing effective chronologies of these events requires the synthesis of multiple radiocarbon ( 14 C) dates. Various “chronometric hygiene” protocols have been used to refine 14 C dating of island colonization, but they can…

  • Re-deposited cryptotephra layers in Holocene peats linked to anthropogenic activity

    Open AccessGraeme T Swindles, Jennifer M Galloway et al.ARTICLEThe Holocene2013Cited by: 3References: 12

    Tephra layers can form useful age-equivalent stratigraphic markers for correlating palaeoenvironmental sequences and they provide information about the spatio-temporal nature of past volcanic ash fall events. The use of microscopic ‘cryptotephra’ layers has both increased the stratigraphic resolution of tephra sequences in proximal areas and extended the distal application of tephrochronology to regions of the world situated far from volcanoes. E…

  • Lake Sediments Record Sensitivity of Two Hydrologically Closed Upland Lakes in Mexico to Human Impact

    Sarah J Davies, E Metcalfe et al.ARTICLEAMBIO2005References: 20

    We provide evidence of rapid, recent environmental change in two lakes in the highlands of central Mexico. Multiple sediment cores were obtained from Lago de Zirahuén (Michoacán) and Laguna de Juanacatlán (Jalisco). Analysis of diatom assemblages, magnetic susceptibility, and metal concentrations was carried out, with the chronology provided by 210Pb dating, 14C dating, and tephrochronology. There is evidence of catchment disturbance during the c…

  • Tephrochronology, Environmental Change and the Norse Settlement of Iceland

    Andrew J Dugmore, Andrew Dugmore et al.ARTICLEEnvironmental Archaeology2000Cited by: 2References: 12

    The first human impacts on the Icelandic environment came with the Norse colonisation or Landnám of the ninth century AD. The colonisation represents a fundamental environmental change that is both rapid and profound. In this paper we assess geomorphological dimensions of the initial settlement period using a tephrochronology that includes the Landnám Tephra, erupted ca. 870 AD, two tenth century AD tephras KR 920 and E 935, and 11 other well dat…

  • Geochemical Characterization of Late Pleistocene and Holocene Tephra Layers from the Basin of Mexico, Central Mexico

    Open AccessBeatriz Ortega‐Guerrero, Beatriz Ortega-Guerrero et al.ARTICLEQuaternary Research1998

    In order to aid palaeoenvironmental research of Late Pleistocene and Holocene deposits of central Mexico, tephra layers collected from the sediments of the Texcoco and Chalco sub-basins, in the southern part of the Basin of Mexico, are geochemically characterized and used as stratigraphic markers. The tephra layers range in composition from basaltic andesites to rhyolites and are calc-alkaline. The tephras range in age from >34,000 to ca. 2600 14…

  • Seven tephra isochrones in Scotland

    Open AccessAndrew J Dugmore, Andrew Dugmore et al.ARTICLEThe Holocene1995Cited by: 40References: 2

    This paper reports the presence and geochemical characteristics of seven separate tephras in Scotland that fell in AD 1510, and about 450 BP, 2100 BP, 3600 BP, 3830 BP, 5600 BP and around 6000 BP. The results come from 14 peat bogs spread throughout the Highlands and Islands where 26 tephra deposits have been characterized using over 400 grain-discrete electron-probe micro-analysis. Firstly, tephras are identified and defined by major element cha…
