Minerals have a chemical composition and crystal structure that reflect the pressure and temperature conditions of the environment in which they formed. When the conditions change, minerals usually undergo transformations to adapt themselves to these new conditions. When these transformations take place in subsurface conditions, where pressure and temperature are usually low, they are commonly driven by the action of a fluid and involve the replacement of the primary minerals by secondary phases. The presence of a fluid triggers the replacement reaction to take place through an interface coupled dissolution-precipitation (ICDP) mechanism. This mechanism makes the kinetics of the transformation to be much faster than if the transformation were developed by diffusion in solid state. Due to the ubiquity and relevance of mineral replacement reactions in subsurface geological environments, numerous experimental studies on the development of these processes in different systems have been carried out over the last two decades. However, many of the parameters controlling these fluid-driven mineral replacement processes are still poorly understood. This PhD thesis seeks to advance in this understanding. With this aim, experiments have been designed to experimentally study the replacement of calcium carbonate and sulphate phases through dissolution-crystallisation reactions that take place in the temperature range between 25°C and 200°C. The thesis is divided into 5 result chapters, which are presented as scientific article and address two major problems…
