Evaluating the Neogene paleoclimatic record of northwestern Luzon from paleoweathering proxies

open access: yesGeoscience Letters
This study examines the applicability of geochemical proxies used in paleoclimatic studies in the South China Sea Basin (SCSB) to decipher paleoweathering and paleoclimatic signatures recorded in the Neogene clastic sediments overlying the Zambales ...

Late Miocene – Early Pleistocene paleogeography of the onshore central Hawke’s Bay sector of the forearc basin, eastern North Island, New Zealand, and some implications for hydrocarbon prospectivity

open access: yes, 2008
The timing of trap formation in relation to the timing of source rock burial and maturation are important considerations in evaluating the hydrocarbon prospectivity of onshore parts of the forearc basin in central Hawke’s Bay.

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.

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.

Note on paramoudra-like carbonate concretions in the Urenui Formation, North Taranaki: possible plumbing system for a Late Miocene methane seep field

open access: yes, 2004
A reconnaissance study of calcitic and dolomitic tubular concretions in upper slope mudstone of the Late Miocene Urenui Formation exposed along the north Taranaki coastline indicates that they have a complex diagenetic history involving different phases ...

Redefining ecosystem integrity for an Anthropocene biosphere: a process‐ and lineage‐based framework for restoration

open access: yesRestoration Ecology, EarlyView.
Restoration increasingly operates in rapidly transforming landscapes shaped by human‐driven global change, where historical reference states no longer represent achievable or even desirable targets. Yet, ecological restoration and conservation management still rely on composition‐based definitions of ecosystem integrity that assume stable reference ...

New insights into the condensed nature and stratigraphic significance of the Late Neogene Ariki Formation, Taranaki Basin

open access: yes, 2008
The Ariki Formation is a distinctive Late Miocene – Early Pliocene marl facies rich in planktic foraminifera, reaching thicknesses in the range 70 - 109 m in most exploration holes drilled into the Western Platform northwest of Taranaki Peninsula.
