The nature, and CO 2 content, of the terrestrial atmosphere in the course of its geologic
evolution has been intimately linked with that of the hydrosphere, biosphere, and lithosphere …

Stable carbon and oxygen isotope vanations in speleothems collected from four locations in
India, viz, Gupteswar (Orissa), Dandak (Chhattisgarh), Sota (Uttar Pradesh), and Akalagavi …

Mantle degassing continually releases gases onto the earth's surface. Over geologically
long time intervals, a general equilibrium probably exists between mantle CO 2 release and …

In the recent years, high-resolution long records from the deep-sea and ice-cores have
offered new research opportunities for Quaternary science. Paleoclimate studies are no …

A prominent middle Eocene warming event is identified in Southern Ocean deep-sea cores,
indicating that long-term cooling through the middle and late Eocene was not monotonic. At …

Abundance and carbon isotope data from an Fe (CO3) OH component in apparent solid
solution in oolitic goethites have been used to infer ancient atmospheric CO2 pressures. A …

Abstract The Mid‐Pliocene Warm Period (MPWP, 2.9 to 3.3 Ma), along with older Pliocene
(3.2 to 5.3 Ma) records, offers potential past analogues for our 400‐ppmv world. The coastal …

Secular variations of the seawater carbon isotopic composition provide evidence for
paleoceanographic and paleoclimatic changes and may serve for chemiostratigraphic …

We report a high-resolution paleomagnetic investigation constrained by new qualitative and
semiquantitative analyses of planktic and benthic foraminifera, nan-nofossil assemblages …
