The chemical weathering of sulfide-bearing rocks can result in the dissolution of carbonate rocks leading to degassing of (Formula presented.) to the atmosphere. While this process has been argued to be a significant geologic source of (Formula presented.), it also perturbs the geological cycles of oxygen and sulfur, triggering a cascade of geochem...
More than 200 years since its initial exploration, Zanda Basin, a high-elevation (3,800–4,500 m above sea), intermountain basin at the foothills of the Himalaya, is the site to some of the earliest fossil discoveries, including the holotype of extinct Tibetan antelope, Qurliqnoria hundesiensis. These fossils also hold the record, in 1823, as the fi...
Marine reptiles and mammals are phylogenetically so distant from each other that their marine adaptations are rarely compared directly. We reviewed ecophysiological features in extant non-avian marine tetrapods representing 31 marine colonizations to test whether there is a common pattern across higher taxonomic groups, such as mammals and reptiles...

Abstract—The paleotemperature curves for water masses and average annual temperatures have been plotted for the first time on the basis of original and published data for the Central and Eastern Tethys for the Jurassic–Quaternary period.

Rodents are the most diverse order of extant mammals, and caviomorph rodents, or New World hystricognaths, have a remarkable morphological disparity and a long fossil record that begins in the Eocene. Chinchilloidea is a poorly understood clade within Caviomorpha, from an evolutionary and phylogenetic perspective. It includes the extant families Ch...

AbstractSm–Nd isotope–geochemical studies of the Cenozoic sand deposits of the Muya Depression (eastern flank of the Baikal rift zone), which is located on the border of the Charo–Olekminskii Geoblock of the Aldan Shield and the Anamakit–Muya Zone of the Baikal–Muya Fold Belt, were carried out. The Nd model ages tNd(DM) were obtained for most of th...

In this paper we review the fragmentary fossil pollen record of Hamamelidaceae which extends back to the middle Eocene until the Early Pleistocene in the Iberian Peninsula. Records of fossil palynomorphs related to Hamamelidaceae are very scarce in the European Cenozoic, in part due to difficulty in confident identification at a generic or even fam...

Calcareous nannofossil assemblages identified in manganese deposits dredged at three sites on the Mozambique Ridge and one on the Jaguar seamount in the Mozambique Basin comprise 61 species, including nine reworked ones. The samples represent cores of nodules or encrustations ranging from 4.04 to 0.00 Ma. Dating by nannofossils suggests bi-modal ag...
In this paper, we propose a high-resolution (HR) sedimentary budget quantification at basin-scale for the Cenozoic deposits of the Pelotas Basin (South Atlantic). A new workflow is implemented including five main steps: (1) basin-scale analysis and characterization, (2) quality control and selection of reference 2D dip-sections, (3) HR seismic stra...
