The causes and effect of temporal changes in magma generation processes in space and time along the Central Andes (13°S – 25°S)
(2015-11-27)This thesis investigates the timing and causes of the transition between two different magmatic regimes during the evolution of the Central Andean uplift. The first volcanic regime is represented by Miocene lava shields, ... -
The geochemistry of detrital rutile - Implications for sedimentary provenance studies and the reconstruction of metamorphic conditions
(2011-08-15)Samples investigated in this study derive from a large range of metamorphic conditions (from diagenetic up to 950°C and 4.5GPa) and geological settings. Main sampling localities were the ... -
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 microscopic dimension of paleoclimate in the EPICA-DML(Antarctica) deep ice core
(2013-03-12)The present work is divided into two main parts: the introductory half and the experimental chapter. Chapter 1 starts with the brief presentation of the scientific project that facilitated the development of the thesis, ... -
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 ...
