|Summary of thesis||
This doctorate study aims at studying the spatial controls, age and origin of stratabound sandstone-hosted and vein Pb-Zn deposits in the Swedish Caledonides. Although considerable high-quality data have been acquired since the 1980s, they have not been exploited under a global perspective and inconsistencies persist between the different genetic models.
The rationale behind this project is to a large extent to scientifically exploit the wealth of new field and drilling data gathered in the last years by the mining company Boliden Mineral AB. These data will mainly be used to construct 3D representations of selected deposits to give insight into the palaeo-hydrology during mineralization, and so, constrain the different models. The hypothesis that economic ore precipitated in places where reduced sulphur was trapped together with hydrocarbons will be examined together with the other proposed models.
