1. Electron Backscatter Diffraction (EBSD) Analysis and Predicted Physical Properties of Shocked Quartz from the Chicxulub Impact Crater, Mexico
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : As one of the most common minerals in crustal rocks, quartz has been widely used as an indicator for shock metamorphism. Shocked quartz is found in the Chicxulub impact crater, an impact crater that has been linked to the Cretaceous-Tertiary extinction ~66 million years ago. READ MORE

2. The Structural Architecture of the Barsele Area, Sweden : Characterising the deformation events and mineralisation
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : Located at an important intersect between orogenic Au deposits in Sweden’s Gold Line and volcanicmassive sulphide (VMS) deposits in the Skellefte Mining District, the Barsele area is of high interest.Currently, the Barsele deposit consists of the Norra VMS deposit and 3 intrusive-hosted orogenic Audeposits: Avan, Central, and Skiråsen which are hosted in a 1876 ± 10 Ma early orogenic granodiorite(Thomas, et al.

3. Structural controls on the shear zone hosted, IOCG-style Kiskamavaara Cu-Co-Au mineralization
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : Sweden is the largest producer of iron ore in the European Union, as well as amongst the top producers for base and precious metals. Much of its mineral wealth derives from northern Norrbotten, type locality of the Kiruna-type-magnetite-apatite ores. READ MORE

4. Structural Reconnaissance Mapping of the Nasa Basement Window, Southern Norrbotten Caledonides
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : Too few documentative descriptions exist from the reactivated Proterozoic Nasa Basement window in Sweden. This re-exposed crustal piece predominantly consisting of 1.8 Ga granite and volcanic basement rock lack structural evidences on maps. READ MORE

5. Elastic Anisotropy of Deformation Zones in both Seismic and Ultrasonic Frequencies: An Example from the Bergslagen Region, Eastern Sweden
University essay from GeofysikAbstract : Estimation of elastic anisotropy, which is usually caused by rock fabrics and mineral orientation, has an important role in exploration seismology and better understanding of crustal seismic reflections. If not properly taken care of during processing steps, it may lead to wrong interpretation or distorted seismic image. READ MORE
