Palaeoclimate evolution and sequence stratigraphy during Pliocene Shizigou stage, Qaidam Basin

open access: yesShiyou shiyan dizhi, 2020
The Qaidam Basin is a large transpressional Mesozoic to Cenozoic basin in the Tibet Plateau, West China. Since the Indosinian Movement, it has been in the subsidence stage and more than 3 trillion cubic meters of natural gas accumulated at the same time.

On the importance of moisture conveyor belts from the tropical eastern Pacific for wetter conditions in the Atacama Desert during the mid-Pliocene [PDF]

open access: yesClimate of the Past, 2023
Geomorphic and sedimentologic data indicate that the climate of today's hyper-arid Atacama Desert (northern Chile) was more humid during the mid-Pliocene to Late Pliocene.

GEOLOGICAL AND GEOPHYSICAL TRANSECT OF THE MIDDLE TIEN SHAN ACROSS THE NARYN AND ATBASHI DEPRESSIONS

open access: yesГеодинамика и тектонофизика, 2022
The article presents the results of integrated geological and geophysical research works dealt with detailed magnetotelluric (MT) sounding and the study of the morphology and spatial position of the sedimentary cover and basement structures along the key

Lacustrine mollusc radiations in the Lake Malawi Basin : experiments in a natural laboratory for evolution [PDF]

open access: yes, 2012
In terminal Pliocene-early Pleistocene times, part of the Malawi Basin was occupied by paleo-lake Chiwondo. Molluscan biostratigraphy situates this freshwater lake either in the East African wet phase between 2.7-2.4 Ma or that of 2.0-1.8 Ma.

Northern Hemisphere Glaciation during the Globally Warm Early Late Pliocene [PDF]

open access: yes, 2013
The early Late Pliocene (3.6 to ~3.0 million years ago) is the last extended interval in Earth's history when atmospheric CO2 concentrations were comparable to today's and global climate was warmer.

Pliocene-Pleistocene marine cyclothems, Wanganui Basin, New Zealand: a lithostratigraphic framework [PDF]

open access: yes, 1995
The Rangitikei River valley between Mangaweka and Vinegar Hill and the surrounding Ohingaiti region in eastern Wanganui Basin contains a late Pliocene to early Pleistocene (c. 2.6-1.7 Ma), c.

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

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

Contribution of the coupled atmosphere–ocean–sea ice–vegetation model COSMOS to the PlioMIP2 [PDF]

open access: yesClimate of the Past, 2020
We present the Alfred Wegener Institute's contribution to the Pliocene Model Intercomparison Project Phase 2 (PlioMIP2) wherein we employ the Community Earth System Models (COSMOS) that include a dynamic vegetation scheme.

Evolution of Pliocene climate cyclicity at Hole 806B (5-2 Ma); oxygen isotope record [PDF]

open access: yes, 1993
A detailed Pliocene oxygen isotope record from the Ontong Java Plateau, based on measurements of the surface-dwelling planktonic foraminifer Globigerinoides sacculifer, was produced for the period from 5 to 2 Ma. The record documents major long and short-
