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).

Introduction to the future of sequence stratigraphy: evolution or revolution?

open access: yes, 2016
Sequence stratigraphy was first developed as concepts and methods from the late 19th to mid 20th century by geologists such as Barrell and Sloss. It is now at the forefront of how sedimentary geologists observe, record, model and predict strata.

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 ...

The Late Miocene Southern and Central Taranaki Inversion Phase (SCTIP) and related sequence stratigraphy and paleogeography [PDF]

open access: yes, 2008
We present a new sequence stratigraphic scheme for Taranaki Basin that identifies four 3rd order duration (3 - 4 m.y.) sequences of Middle Miocene to Pleistocene age.

Late Quaternary lake filling and drying in northern Australia's largest freshwater lake

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Lake Woods, Jurrkulu, is northern Australia's largest freshwater lake filled today in strong Indo–Australian summer monsoons (IASM) to maximum depths of ~5 m. On the western margins of the lake, two large arcuate ridges occur 20 to 40 m above the lake floor and inset within these are other mid‐elevation lake deposits, such as depositional ...

Sequence stratigraphy and architectural elements of the Giant Foresets Formation, northern Taranaki Basin, New Zealand [PDF]

open access: yes, 2006
The modern continental margin in northern Taranaki Basin is underlain by a thick, mud-dominated, Pliocene and Pleistocene succession (Giant Foresets Formation, GFF) clearly imaged in seismic reflection datasets.
