Ngarrawa (mound spring) sediments as archives of Holocene environmental change in arid central Australia: Insights from Itrax XRF scanning

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Central Australia's ngarrawa, or ‘mound springs’, are unique hydrological systems that serve as some of the only near‐permanent sources of water and continuous sediment deposition in Australia's arid interior. As such, they hold significant potential as palaeo‐climate and ‐environmental archives in a region where many aspects of past climate ...

Mercury cycling during the last glacial period in Arctic Lake El'gygytgyn, NE Russia

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Tectonic processes play a key role in the global mercury (Hg) cycle on geological timescales, by mobilising Hg from deep Earth reservoirs to the surface. These natural fluxes also introduce a dynamic component to the terrestrial Hg cycle that can interact with other environmental signals and influence Hg delivery to sedimentary records.

The Great Fossil Mine of the southern North Sea: exploring the potential of submerged Palaeolithic archaeology

open access: yes, 2014
This research explores the potential of the submerged Palaeolithic archaeology of the southern North Sea for answering questions about how hominins occupied and adapted within their environments in these northerly latitudes throughout the Pleistocene ...

Pleistocene-Pliocene strontium-isotope ratios of ODP Site 107-653 (Table 1)

open access: yes, 1990
Strontium isotopic determinations were made on samples from the Pliocene-Pleistocene sequence recovered at ODP Hole 653A, the proposed "deep-sea type section" for the Mediterranean region.

Carbon isotope geochemistry of organic matter in volcanic paleosols constrains paleo‐environmental variations

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Fiorano quarry paleosol developed within the Colli Albani volcanic district (Italy) in the time interval bracketed by the deposition of the Pozzolanelle pyroclastic‐flow unit (365 ± 4 ka) and the emplacement of the Capo di Bove lava flow (277 ± 2 ka).

New constraints on the postglacial evolution of Lago Maggiore, Northern Italy

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Lago Maggiore is situated in an overdeepened valley reach at the southern margin of the European Alps, and its thick sediment infill allows the reconstruction of the postglacial valley and lake evolution. We study here the sedimentary succession in the lower Ossola Valley, which is infilled by ~500 m of deposits. In a marginal position, a core

Review of the Salpausselkä ice‐marginal formations in Finland

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Extensive Salpausselkä ice‐marginal formations were deposited in southern and eastern Finland during the Weichselian deglaciation. These comprise three major ridges (I, II, and III Salpausselkäs) and their eastern counterparts (Tuupovaara, Koitere, and Pielisjärvi), together forming laterally continuous ice‐marginal formations extending ...
