Late Neogene Erosion of the Alps: A Climate Driver?

open access: yesAnnual Review of Earth and Planetary Sciences, 2010
As with many mountain belts globally, the Alps have seen a large increase in sediment yield in the late Neogene. The hypothesis that this increase results from climate-change impacts on erosion rate over the past ∼5 Ma is testable, given the extensive work completed in the Alps.

Geochemical investigation of impactites from the Boltysh impact structure and possible relationship to early Danian sediments from the Umbria–Marche Basin, Italy

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Within the Danian Scaglia Rossa Formation appears a regionally correlatable horizon cutting across multiple sections and outcrops within the Umbria–Marche Basin of NE Italy, where it is intercalated with uniform pelagic carbonate successions. This horizon is called “ALE layer” and has tentatively been interpreted as a fine‐grained volcanic ash.

Neogene plate tectonic reconstructions and geodynamics of North Island sedimentary basins: Implications for the petroleum systems

open access: yes, 2006
Although the modern Australia-Pacific plate boundary through New Zealand is relatively straight, there have been significant changes in its geometry during the Neogene. Within the North Island sector there has been a fundamental transition from an Alpine

Seismic stratigraphy and history of deep circulation and sediment drift development in Baffin Bay and the Labrador Sea

open access: yes, 1989
Drilling results and seismic-reflection records at and across Ocean Drilling Program (ODP) Sites 645 (western Baffin Bay), 646, and 647 (Labrador Sea) provide important constraints on the history of deep-water circulation and sedimentation in response to

Ibero‐Balearic plant disjunctions: genomic support for rapid and recurrent long‐distance colonizations of the endangered Diplotaxis ibicensis (Brassicaceae) despite no dispersal syndromes

open access: yesPlant Biology, EarlyView.
Genotyping‐by‐sequencing data reveal six well‐defined clades in the endangered Diplotaxis ibicensis, endemic to the western Mediterranean Basin and indicate rapid and recurrent long‐distance colonisations across the Balearic Islands and the eastern Iberian coast despite the absence of dispersal syndromes.

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

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.

Porosity Preservation in Deeply Buried (8500 m) Jurassic Calcareous Mudstones of the Vienna Basin (Austria)

open access: yesTerra Nova, EarlyView.
ABSTRACT Significant porosity of more than 5% was found at depths of more than 8500 m in poorly sorted, calcareous mudstones of the Malmian Mikulov Formation. These overpressured rocks are the main hydrocarbon source rock in the Vienna Basin. Core samples from present‐day depths of 8150 m to 8550 m were analysed using X‐ray diffraction and scanning ...

Late Miocene-Early Pliocene Matemateaonga Formation in eastern Taranaki Peninsula: A new 1:50,000 geological map and stratigraphic framework

open access: yes, 2004
In recent years the Matemateaonga Formation has become an additional exploration play in Taranaki Basin. Exploration interest has been stimulated by the success of Swift Energy Company in the Rimu/Kauri prospect (38719), located near south Taranaki Coast.

Neogene benthic foraminiferal stratigraphy and deep water history of Sites 645, 646, and 647, Baffin Bay and Labrador Sea

open access: yes, 1989
Benthic foraminifers were examined from Neogene sediments of Ocean Drilling Program (ODP) Sites 645, 646, and 647 to determine their biostratigraphy and to place constraints on the paleoceanographic history of Baffin Bay, Eirik Ridge, and the Gloria ...

Monsoon versus uplift in southwestern China : Late Pliocene climate in Yuanmou Basin, Yunnan

open access: yes, 2011
Yuanmou Basin of Yunnan, SW China, is a famous locality with hominids, hominoids, mammals and plant fossils. Based on the published megaflora and palynoflora data from Yuanmou Basin, the climate of Late Pliocene is reconstructed using the Coexistence ...
