  1. 1. 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

  3. 2. The “ultramafic” Intrusion’s within the peridotite from Härbergsdalen : Petrological characterization of infiltration record within the lithospheric mantle

    University essay from Uppsala universitet/Mineralogi, petrologi och tektonik

    Author : Per Volter; [2022]
    Keywords : ;

    Abstract : The mantle constitutes ~80% of Earths volume, however, due to its location deep beneath Earth’s surface the mantle is inaccessible to study in situ. Despite this, we still have information about its composition thanks to seismic studies which haven proven the mantle to be in generally homogenous and dominated by a rock called peridotite.

  4. 3. The Roots of a Magma Chamber, the Central Intrusion, Rum, NW-Scotland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Tobias Mattsson; [2014]
    Keywords : Rum; Layered Ultrabasic Intrusion; Long Loch Fault; 3D modelling; Rum; Minerallagrad magmakammare; Long Loch Förskastningen; 3D modellering;

    Abstract : The island of Rum in the Inner Hebrides, NW-Scotland, hosts a central volcanic complex that is part of the British-Irish Palaeogene Igneous Province situated in NE- Ireland and NW- Scotland. On Rum, rocks from several stages of Palaeogene magmatic activity have been exposed by millions of years of erosion. READ MORE

  5. 4. Chromite in serpentine mud volcanoes of the Mariana forearc: Implications for abiotic organic reactions

    University essay from Institutionen för geologiska vetenskaper

    Author : Iga Sagatowska; [2010]
    Keywords : ;

    Abstract : The Mariana convergent plate margin is a non- accretionary subduction system in the western Pacific Ocean. Subduction of the Pacific plate causes dissolution of carbonate minerals releasing inorganic carbon, and causes dehydration of hydrous minerals in the subducted slab, generating hydrous fluids.

  6. 5. A geochemical characterization of the lower part of the Miocene shield-building lavas on Gran Canaria

    University essay from Lunds universitet/Geologiska institutionen

    Author : Romina Peetz; [2009]
    Keywords : Gran Canaria; shield-building lavas; Güigüi Formation; Earth and Environmental Sciences;

    Abstract : Ocean islands offer a great potential to provide information about mantle processes and the composition of the mantle. Gran Canaria is located in the centre of the Canary Island Archipelago and is well suited for such studies. A comprehensive study of the lower Miocene shield-building lavas is performed for this thesis. READ MORE
