1. Hydrogen in nominally anhydrous silicate minerals : Quantification methods, incorporation mechanisms and geological applications
Sammanfattning : The aim of this thesis is to increase our knowledge and understanding of trace water concentrations in nominally anhydrous minerals (NAMs). Special focus is put on the de- and rehydration mechanisms of clinopyroxene crystals in volcanic systems, how these minerals can be used to investigate the volatile content of mantle rocks and melts on both Earth and other planetary bodies (e.

2. Water as a trace component in mantle pyroxene: Quantifying diffusion, storage capacity and variation with geological environment
Sammanfattning : In this study, distribution and diffusion of water in pyroxene are examined in an effort to explain the water content variation observed in natural pyroxene. Water is a common trace component in many nominally anhydrous minerals (NAMs) from the Earth's crust and mantle and greatly impacts their physical properties. LÄS MER
3. Hydrogen diffusion and storage mechanisms in diopside
Sammanfattning : Hydrogen is a widespread trace element in many nominally anhydrous minerals (minerals without water or hydroxyl ions in their structural formula) from the Earth's crust and mantle. The hydrogen is normally incorporated in the form of hydroxyl ions and can be regarded as structurally bound water. LÄS MER
