Abstract
The main objectives of this thesis were to study basalt alteration and formation of secondary phases and their implications on Mars (Paper I), and potential consequences for petroleum reservoirs influenced by the presence of mafic lithologies (Papers II and III). This new knowledge was to be acquired using several analytical tools: XRD, XRF, NIR, SEM-EDS, performing hydrothermal batch experiments, geochemical modelling and petrographic studies of core samples. The thesis consists of an introduction providing background information on basalt alteration and implications on Earth and Mars, a general scientific background section, and three research papers. The three papers in the last sections constitute the main part of this thesis.List of papers
