The Influence of Fluorine, Chlorine and Water on the Rheology and Structure of Na2O-CaO-Al2O3-SiO2 Melts
(2014-05-21)This study investigates the influence of 1.6 to 14.5 mol% water, 1.1 to 18.3 mol% fluorine (F) and 0.5 to 1.4 mol% chlorine (Cl), alone and combined, on the structure and viscosity of peralkaline and peraluminous Na2O CaO ... -
The onset of planet formation inferred from isotope anomalies in meteorites
(2024-12-18)Variations in the isotopic compositions of extraterrestrial samples provide important insights into the formation of planetesimals—the fundamental building blocks of planets. Particularly, isotopic anomalies of nucleosynthetic ... -
Towards a high-quality interannual to millennial ice-core based temperature reconstruction for East-Antarctica
(2022-09-16)Instrumental observations of climate cover only the past ~200 years. Our knowledge about historical natural climate variability beyond this time is exclusively based on climate proxies, stored within natural archives. ... -
Triple oxygen (16O, 17O, 18O) and carbon (12C, 13C) isotope variations in bioapatite of small mammals – new insights concerning the reconstruction of palaeo‐CO2 concentrations and palaeotemperatures
(2013-02-25)The ratios among the stable isotopes of oxygen (16O, 17O, 18O) and carbon (12C, 13C) in biogenic apatite of mammal teeth and bones have the potential to provide insight into the isotopic composition of the respective oxygen ... -
Triple oxygen isotope study on the Earth-Moon system
(2021-12-23)Triple oxygen isotope systematics (Δ'17O) are an established tool to trace and classify extraterrestrial material. This tool is used in the field of cosmochemistry to study the genetic link between different Solar System ... -
Triple oxygen isotope variations in natural and anthropogenic carbon dioxide
(2013-03-19)The oxygen and carbon isotope composition (18O/16O and 13C/12C) of atmospheric carbon dioxide is an excellent tool to investigate the atmospheric CO2 cycle. In recent ... -
Triple Oxygen Isotopes of Cherts : Implications for the δ18O and Temperatures of Early Oceans
(2017-06-19)The temperature of Earth’s earliest oceans, in which life may have first originated, remains a controversial issue in Earth science. Over the last 50 years, many studies have attempted to apply the temperature dependent ... -
Volatilitätskontrollierte Fraktionierung refraktär-lithophiler Elemente in Meteoriten und der Erde
(2014-08-14)During the condensation of the elements in the early solar system, volatility-controlled fractionations occurred. Such fractionations of refractory lithophile elements in individual chondrite components and between bulk ...
