1. Investigating the potential of systematic optical petrography in a geometallurgical context : A case study on boulder characterization from Rajapalot property, Finland
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : Geometallurgy describes a holistic approach to mining (integrating geological, metallurgical, geotechnical, environmental, and more parameters) with the goal to improve the efficiency and sustainability of a mining operation. The potential of systematic optical petrography in a geometallurgical context was investigated in this study, as well as how petrography may be useful across disciplines in several blocks of the mining value chain.

2. Character and Evolution of Ore Mineralisation in the Te-Rich Enåsen Au-Cu Deposit, Central Sweden
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The Enåsen gold deposit is located in Gävleborg county in central Sweden. Mining operations at Enåsen took place from 1984 to 1991 with Au as the main target for exploitation. The deposit has been interpreted as a metamorphosed Palaeoproterozoic analogue to near-recent epithermal Au mineralisations of a high sulphidation type. READ MORE

3. 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.

4. Petrography and Thermodynamic Modelling of Svecofennian Arsenic-bearing Metasupracrustal Rocks in the Arlanda Area, West-Central Fennoscandian Shield
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The Arlanda area is a construction intensive area facing problems with risk of leaching of arsenic (As) from the bedrock to surface- and groundwater. Construction projects in the area have had problems with high levels of As in the bedrock and the risk of leaching increases through processing of aggregates and blasting of the bedrock. READ MORE

5. Petrography and Mineral Chemistry of the Sälskär Breccia (Alnö Alkaline Complex, Central Sweden)
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Primitive magmas can provide important details about the mantle from which they are derived. In this thesis, petrographic observations and new mineral chemistry analyses of the Sälskär breccia from the Alnö alkaline complex, central Sweden, are reported. READ MORE
