3. 2. Lejarfjället Garnet(?) Peridotite – Origin and Petrological Characterization of Symplectitic Aggregates in Ultramafic Rocks

   University essay from Uppsala universitet/Mineralogi, petrologi och tektonik

   Author : Felicia Eriksson; [2022]
   Keywords : ultramafic; high-pressure metamorphism; peridotite; garnet breakdown; Scandinavian Caledonides; ultramafisk; högtrycks metamorfos; peridotit; granat; skandinaviska kaledoniderna;

   Abstract : Ultramafic rocks are abundant in the Earth’s mantle but rare on the surface. Since no in-situ samples from the mantle can be collected, mantle rocks provide knowledge of mechanisms operating in the mantle and large-scale processes that brought them up to the surface. READ MORE

5. 4. Submarine Alteration of Seamount Rocks in the Canary Islands: Insights from Mineralogy, Trace Elements, and Stable Isotopes

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Aduragbemi Oluwatobi Sofade; [2018]
   Keywords : Canary Islands; seamounts; submarine alteration; trace elements; nannofossils; Kanarieöarna; djuphavsberg; undervattensomvandling; spårämnen; nanofossiler;

   Abstract : Seamounts play an important role in facilitating the exchange of elements between the oceanic lithosphere and the overlying seawater. This water-rock interaction is caused by circulating seawater and controls the chemical exchange in submarine and sub-seafloor rocks. READ MORE

6. 5. Magma Evolution of the Cerro Bayo Laccolith in the Chachahuén Volcanic Complex, Argentina

   University essay from Uppsala universitet/Institutionen för geovetenskaper
