  • Palynological evidence from a sub-alpine marsh of enhanced Little Ice Age snowpack in the Marrakech High Atlas, North Africa

    Open AccessBenjamin A Bell, William J Fletcher et al.ARTICLEVegetation History and…2021Referencias: 8

    The grazing lands of the High Atlas are vulnerable to climate change and the decline of traditional management practices. However, prior to the mid-20th century, there is little information to examine historical environmental change and resilience to past climate variability. Here, we present a new pollen, non-pollen palynomorph (NPP) and microcharcoal record from a sub-alpine marsh (pozzine) at Oukaïmeden, located in the Marrakech High Atlas, Mo…

  • The “missing glaciations” of the Middle Pleistocene

    Open AccessPhilip D Hughes, Philip L Gibbard et al.ARTICLEQuaternary Research2020

    Global glaciations have varied in size and magnitude since the Early–Middle Pleistocene transition (~773 ka), despite the apparent regular and high-amplitude 100 ka pacing of glacial–interglacial cycles recorded in marine isotope records. The evidence on land indicates that patterns of glaciation varied dramatically between different glacial–interglacial cycles. For example, Marine Isotope Stages (MIS) 8, 10, and 14 are all noticeably absent from…

  • Are the widespread scatters of stone artefacts on dune surfaces in southeastern arid Australia really late Holocene in age

    Philip D Hughes, Philip Hughes et al.ARTICLEAustralian Archaeology2020Referencias: 16

    Vast numbers of stone artefact clusters (commonly called artefact scatters) occur on dune surfaces throughout southeastern arid Australia, virtually all of them undated. They were interpreted by researchers in the 1980s and 1990s as being mainly of late Holocene age on the basis of their surface or near-surface locations and the composition of their assemblages, which include backed artefacts, tulas and unifacial points. In this article, we analy…

  • Rapid age assessment of glacial landforms in the Pyrenees using Schmidt hammer exposure dating (SHED)

    Open AccessMatt D Tomkins, Jason M Dortch et al.ARTICLEQuaternary Research2018

    Schmidt hammer (SH) sampling of 54 10 Be-dated granite surfaces from the Pyrenees reveals a clear relationship between exposure and weathering through time (n=52, R 2 =0.96, P 10 Be-SH calibration curve, 100 surfaces were sampled from five ice-front positions in the Têt catchment, eastern Pyrenees, with results verified against independent 10 Be and 14 C ages. Gaussian modelling differentiates Holocene (9.4±0.6 ka), Younger Dryas (12.6±0.9 ka), O…

  • Global glacier dynamics during 100 ka Pleistocene glacial cycles

    Open AccessPhilip D Hughes, Philip L GibbardARTICLEQuaternary Research2018

    Ice volume during the last ten 100 ka glacial cycles was driven by solar radiation flux in the Northern Hemisphere. Early minima in solar radiation combined with critical levels of atmospheric CO 2 drove initial glacier expansion. Glacial cycles between Marine Isotope Stage (MIS) 24 and MIS 13, whilst at 100 ka periodicity, were irregular in amplitude, and the shift to the largest amplitude 100 ka glacial cycles occurred after MIS 16. Mountain gl…

  • Quaternary Glaciations

    Open AccessPhilip L Gibbard, Jürgen Ehlers et al.CHAPTERInternational Encyclopedia of…2018

    The Quaternary is synonymous with extensive glaciation of Earth's mid‐ and high latitudes. Although there were local precursors, significant glaciation began in the Oligocene in eastern Antarctica. It was followed by glaciation in mountain areas through the Miocene (in Alaska, Greenland, Iceland, and Patagonia), later in the Pliocene (e.g., in the Alps, the Bolivian Andes, and possibly in Tasmania), and in the earliest Pleistocene (New Zealand, I…

  • Phase 1

    Tim Denham, Jack Golson et al.CHAPTERTen Thousand Years of Cultivation…2017

    Evidence of past human activities sealed by grey clay was first discovered during stratigraphic recording of plantation drains at Kuk in 1974. Excavations occurred at the site in subsequent years (1975-77 and 1998) to determine more fully the character of the finds (Fig. The archaeological remains, which date to 10,000 years ago, are unique to Kuk and have two major components: a palaeochannel (a prehistoric channel) and a palaeosurface (an old b…

  • Rapid thinning of the Welsh Ice Cap at 20–19 ka Based on 10 Be Ages

    Open AccessPhilip D Hughes, Neil F Glasser et al.ARTICLEQuaternary Research2016

    New 10 Be ages from the summits of three mountain areas of North Wales reveal a very similar exposure timing as the Welsh Ice Cap thinned after the global Last Glacial Maximum. Eight bedrock and one boulder sample gave a combined arithmetic mean exposure age of 19.08 ± 0.80 ka (4.2%, 1σ). Similar exposure ages over a 320 m vertical range (824 to 581 m altitude) show that ice cap thinning was very rapid and spatially uniform. Using the same produc…

  • Prehistoric mining at Olympic Dam in arid South Australia

    Open AccessMarjorie Sullivan, Philip D Hughes et al.ARTICLEArchaeology in Oceania/Archæology…2014Citada por: 2Referencias: 7

    A site in the Olympic Dam area, recorded during archaeological surveying as a silcrete quarry, was investigated. Hand‐excavated squares and subsequent machine‐excavated trenches revealed an ancient “mine” rather than a simple surface quarry. Blocks of high‐quality silcrete were levered from below the ground surface and many were knapped in the immediate area. Rubble in the pit backfills included large numbers of flakes. Single‐grain optical dates…

  • Terminological Debate in the Upper Hunter Valley

    Philip D Hughes, Philip Hughes et al.ARTICLEAustralian Archaeology2011

    Archaeologists have variously used the terms ‘indurated mudstone’ and ‘tuff’ as a description for the fine-textured, very hard, yellowish, orange, reddish-brown or grey rocks from the upper Hunter Valley from which many of the stone artefacts there were made. The desire of archaeologists working in the region to offer a precise and accurate geological description of this material has fuelled debate about whether ‘tuff’ or ‘mudstone’ is the most a…

  • Application of a degree-day model to reconstruct Pleistocene glacial climates

    Open AccessPhilip D Hughes, Roger J BraithwaiteARTICLEQuaternary Research2008

    There is empirical evidence of a nonlinear relation between annual precipitation, or accumulation, and summer mean temperature at the equilibrium line altitude (ELA) on glaciers around the world. The degree-day model gives a similar relation between accumulation and summer temperature, although instead of a single universal curve there is a family of curves depending upon the annual temperature range. Furthermore, the degree-day model also gives …

  • Media and bushfires

    EN Cohen, Philip D Hughes et al.ARTICLEEnvironmental Hazards2007Referencias: 1

    This paper examines the ways residents in the Grampians area in the Australian state of Victoria used their local and their state and national based media before, during and after the 2006 bushfires (wildfires). The researchers were particularly concerned to understand how residents evaluated media sources as trustworthy and credible in relation to bushfire warnings and information about the fires delivered in the media. Analysis of data derived …
