1. 1. The Crystal Size Distribution of Cerro Bayo

   University essay from Uppsala universitet/Mineralogi, petrologi och tektonik

   Author : Elin Kuylenstierna; [2018]
   Keywords : Crystal Size Distribution CSD ; magma chamber; igneous rock texture; Kristallstorleksfördelning CSD ; magmakammare; magmatisk bergartstruktur;

   Abstract : To understand the complex structure of magmatic plumbing systems beneath volcanoes, one needs to study the different textures shown in the igneous rocks produced by the volcano in question. By doing this, one can get a clue of the processes that resulted in the final rock. READ MORE

3. 2. Formation of Sulphides in the Canadian High Arctic Large Igneous Province; Testing the Influence of Sedimentary Rocks

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Erika Hagerfors; [2018]
   Keywords : LIPs; HALIP; SIMS; sulphur isotopes; Ni-Cu-PGE ores; environmental deterioration; LIPs; HALIP; SIMS; svavelisotoper; Ni-Cu-PGE malmer; klimatförändring;

   Abstract : Large Igneous Provinces (LIPs) form during short-lived pulses of extensive magmatic activity. LIPs are known for their ability to affect global climate as well as for their Ni-Cu-PGE ore potential. READ MORE

4. 3. Magma Evolution of the Cerro Bayo Laccolith in the Chachahuén Volcanic Complex, Argentina

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Yang Sun; [2018]
   Keywords : Cerro Bayo laccolith; Chachahuén volcano; Thermobarometry; Plagioclase; Amphibole; Clinopyroxene; Cerro Bayo岩盖，Chachahuén火山，阿根廷，温压计，斜长石，角闪石，单斜辉石; Cerro Bayo lakkolit; Chachahuén vulkan; termobarometri; plagioklas; amfibol; klinopyroxen;

   Abstract : The Chachahuén volcanic complex, with the Cerro Bayo laccolith as one of the largest intrusions, is part of back-arc Payenia volcanic province in western central Argentina. Laccoliths show potential for generating oil in sedimentary basins and producing ore deposits. READ MORE

5. 4. The Formation of Granite Magma Chambers in the Mourne Mountains, Northern Ireland

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Maria Björkgren; [2017]
   Keywords : granite; magma chamber; Mourne Mountains; space problem; AMS; granit; magmakammare; Mournebergen; space problem; AMS;

   Abstract : The Mourne Mountains situated in County Down, Northern Ireland, mainly consists of solidified granite magma chambers that intruded ~ 56 million years ago into the surrounding greywacke. How granite magma chambers are emplaced in the crust has for years been a debate amongst scientist of volcanology, and is referred to as the ‘space problem’ debate. READ MORE

6. 5. 3D Modelling of the Tejeda Cone-Sheet Swarm, Gran Canaria, Canary Islands, Spain

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Lisa K. Samrock; [2015]
   Keywords : Cone-sheet swarm; 3D modelling; Tejeda caldera; Gran Canaria; magma chamber reconstruction; sheet intrusions; Inverterade koniska intrusionssvärmar; 3D-modellering; Tejeda kaldera; Gran Canaria; rekonstruktion av magmakammare; magmatiska intrusioner;

   Abstract : Cone-sheet swarms are magmatic sheet intrusions and part of volcanic plumbing systems and are pathways for magma to the Earth’s surface, where they feed volcanic eruptions. The analysis of cone-sheets provides information on the geometry of the magmatic plumbing system of a volcano and allows to understand processes and dynamics of magma transport. READ MORE
