Testing the impact of diagenesis on the delta O-18 and delta C-13 of benthic foraminiferal calcite from a sediment burial depth transect in the equatorial Pacific [PDF]

open access: yes, 2013
Stable oxygen and carbon isotope (δ18O and δ13C) values measured in foraminiferal calcite are one of the primary tools used in paleoceanography. Diagenetic recrystallisation of foraminiferal calcite can act to reset primary isotopic values but its ...

Late oligocene early miocene alkaline magmatism in the central Altiplano of Bolivia

open access: yes, 1996
Les laves Oligocène supérieur à Miocène inférieur de la formation Tambillo affleurent suivant une bande NNW-SSE de plus de 80 km le long de la bordure NE du Salar de Uyuni. Ces laves basaltiques à andésitiques, mises en place sous forme de sills, dykes et coulées sont d'affinité alcaline ; elles dérivent d'un magma produit par fusion à taux modéré de ...

Reduced convergence within the Tibetan Plateau by 26 Ma?

open access: yesGeophysical Research Letters, 2017
Understanding the dynamics of double‐thickening and uplifting of the Tibetan crust requires constraints on the magnitude and timing of crustal shortening.

Latitudinal distribution of paleotemperature on land and sea from early Cretaceous to middle Miocene [PDF]

open access: yes, 1994
Paleotemperature data from the of oceans and the continents are summarized for the interval from the early Cretaceous through the middle Miocene. The data are contoured on diagrams of age vs latitude after adjustments for the known occurrences of ...

Evolutionary palaeoecology of European rhinocerotids across the Oligocene–Miocene transition

open access: yesRoyal Society Open Science
The Oligocene–Miocene transition witnessed great environmental and faunal changes, spanning from late Oligocene to early Miocene (MP28–MN3). Its drivers and consequences on mammals are, however, poorly understood.

Marked Ericales diversity in late Oligocene–Early Miocene palynofloras from northern Thailand suggests stratified mountain forests

open access: yesJournal of Systematics and Evolution
AbstractFossil Ericales pollen from late Oligocene to Early Miocene sediments of the Ban Pa Kha Subbasin, Li Basin, northern Thailand, were examined using the single‐grain method. A total of 24 different ericalean pollen types belonging to Ebenaceae (Diospyros), Ericaceae (Cassiope, Vaccinium, and Rhododendron), Pentaphylacaceae (Adinandra), Sapotaceae,
