Influence of oxygen fugacity on the viscosity of CO2-, H2O-, and halogen-bearing basaltic melts
(2019-03-04)Abstract The aim of this study is to demonstrate the effect of chlorine (Cl-), fluorine (F-), water (H2O) and carbon dioxide (CO2) on the viscosity of basaltic melts and a comparison to literature models. The basaltic ... -
Physical and thermodynamic properties of aluminosilicate melts as a function of composition
(2008-04-25)Viscosity, heat capacity, density, compressibility, thermal conductivity, thermal expansion, diffusivity, surface tension of melts are all controlled by the melt structure. The structure of the melt is a function ... -
The Distribution of Water in the Lunar Magmatic Ocean
(2023-07-17)Water plays an important role for many geological and organic processes. Nevertheless, it is still unclear why our Earth has such large quantities of it. Either it has been part of the building blocks of our planet or was ... -
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 ... -
Unmixing of Phosphorus-bearing Melts on Earth and Mars
(2019-04-17)The aim of this study lies in the investigation on unmixing in aluminosilicate melts. Therefore, six glasses of peralkaline and peraluminous compositions were synthesized in the system CaO-Al2O3-SiO2, Na2O-Al2O3-SiO2 and ... -
Violence and volume: an experimental study of CO2 driven eruptions of Colli Albani
(2022-04-07)This thesis presents the first rheological investigations of melts from the Colli Albani Volcanic District (CAVD) near Rome (Italy). Despite their silica-poor (< 45 wt%) and ultrapotassic composition – indicating a low ...
