1. Petrography of impactites from the Dellen impact structure, Sweden
University essay from Lunds universitet/Geologiska institutionenAbstract : Identification and characterization of shock-metamorphic features in hypervelocity impact craters is important for our understanding of how shock waves interact with geologic materials and how impact craters form, which in turn is essential to our understanding of what role impact cratering played in the development of our solar system. Of particular interest are accessory minerals like apatite, which contains various volatiles that can affect the atmosphere of a body, or magnetite whose magnetic properties constitute a remote sensing indicator which allows us to study and understand the internal structures of distant bodies.

2. Spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, northern Tanzania
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : In Tanzania, approximately 76% of the drinking water supplies is dependent on groundwater sources. However, the groundwater in north Tanzania is susceptible to contamination by arsenic and fluoride. This study examines the spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, located in northern Tanzania. READ MORE

3. EBSD Investigation of High-Temperature Magnetite from Apatite-Iron-Oxide Deposits: Implications for the Formation of Giant Kiruna-Type Deposits
University essay from Uppsala universitet/Mineralogi, petrologi och tektonikAbstract : European iron production is to a large extent dependant on massive Kiruna type apatite-iron ore deposits. In this contribution, high-temperature magnetite samples from apatite-iron-oxide deposits are investigated by means of Electron Backscattered Diffraction. However, the origin of Kiruna-type deposits is still unresolved. READ MORE

5. Metamorphic microtextures and mineral assemblages in orthogneisses in NW Skåne – how do they correlate with technical properties?
University essay from Lunds universitet/Geologiska institutionenAbstract : Glacifluviala avlagringar har varit de vanligaste källorna för byggmaterial i Sverige under de senaste decennierna. De är dock ändliga resurser som måste bevaras eftersom de också fungerar som akvifärer. READ MORE
