Late Oligocene–early Miocene transformation of postcollisional magmatism in Tibet

Geology, 2019
Abstract Uplift of the Tibetan Plateau is thought to be one of the most important orogenic and climate forcing events of the Cenozoic Era, associated with geodynamic changes related to India-Asia collision and subsequent continental lithosphere subduction.

A Late Oligocene-Early Miocene cool climate flora in Tasmania

Alcheringa: An Australasian Journal of Palaeontology, 1991
The Late Oligocene-Early Miocene Monpeelyata deposit occurs at 920 m above sea level on the Tasmanian Central Plateau, and was probably at least 700 m a.s.l. at the time of deposition. The palynoflora is dominated by Nothofagidites emarcidus/heterus (43%) and Phyllocladidites mawsonii (45%), although neither is represented in the macroflora.

Late Oligocene–Early Miocene paleosols of distal fluvial systems, Ebro Basin, Spain

Palaeogeography, Palaeoclimatology, Palaeoecology, 2007
Abstract The study of paleosols can be a vital tool in the paleoenvironmental interpretation of continental deposits because their physical and chemical characteristics are a reflection of variations in aspects of soil formation. Changes in paleosol characteristics can be used to determine the architecture and nature of parent material, paleosol ...

First macroflora data from La Val (Late Oligocene/Early Miocene), Estadilla (Huesca, Spain)

Historical Biology, 2014
This paper reports a previously unknown leaf-flora from the Upper Oligocene/Lower Miocene of the Ebro Basin, NE Spain, a period with a relatively poor vascular-plant fossil record in Southern Europ...

Late Oligocene-Early Miocene thrusting in southern East Kunlun Mountains, northern Tibetan plateau

Journal of Earth Science, 2009
Southward thrusting occurred in Late Oligocene-Early Miocene in southern East Kunlun (昆仑) Mountains formed the South Kunlun thrust (SKT). Permian strata and Triassic rocks were thrusted over the Paleocene-Eocene red-beds of Fenghuoshan (风火山) Group and Oligocene brownish red conglomerate and sandstone of Yaxicuo (雅西错) Group along SKT faults, formed ...

Confirmation of a Late Oligocene-Early Miocene Age of the Deseadan Salla Beds of Bolivia

The Journal of Geology, 1987
Three new fission-track (zircon) and four new K-Ar (biotite) dates corroborate a late Oligocene-early Miocene age (22-28 Ma) for the Salla Beds of Bolivia. These ages contrast markedly with the previously accepted age of about 35 Ma for these strata and their contained faunas, and recasts of order and chronology of interchange between New World and Old

Palynology of the late Oligocene–early Miocene Newvale Mine, Gore Lignite Measures, Southland, New Zealand

Palaeontographica Abteilung B, 2018
The warm-temperate to subtropical vegetation of New Zealand during the late Oligocene–early Miocene was far more diverse than today, despite being at almost the same latitude. Well-preserved spores and pollen from the late Oligocene–early Miocene Gore Lignite Measures at Newvale Mine, southern New Zealand, add a regional aspect to the diversity, based ...

Leaf fossils of Proteaceae tribe Persoonieae from the Late Oligocene–Early Miocene of New Zealand

Australian Systematic Botany, 2010
Fossils from the Newvale lignite mine, Southland, are the first substantiated foliar records of Proteaceae subfamily Persoonioideae. The fossils possess very large stomata, a probable synapomorphy for Persoonioideae, and within Proteaceae the combination of this feature and more or less parallel-aligned, brachyparacytic stomatal complexes and undulate ...
