1. 1. The Significance of Giant Flank Collapses on Magma Ascent in the NE Rift Zone of Tenerife, Canary Islands: A Structural Modelling and Diffusion Approach

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Kristoffer Ånäs; [2021]
   Nyckelord :Tenerife; volcanic rift zones; analogue gelatine experiments; dykes; Fe-Mg diffusion; ankaramite; Teneriffa; vulkaniska sprickzoner; analoga gelatinexperiment; gångar; Fe-Mg diffusion; ankaramit;

   Sammanfattning : On the volcanic ocean island Tenerife in the Canary archipelago, several giant flank collapses haveoccurred over the last one million years. The link between the lateral collapses and the resultingvolcanism in the rift zones is not fully understood and was investigated within the framework of thisproject. LÄS MER

3. 2. Subsidence in rift zones : analyzing results from repeated precision leveling of the Vogar Profile on the Reykjanes Peninsula, Southwest Iceland

   Sammanfattning : The mid-Atlantic ridge connects with land at the Reykjanes peninsula, Southwest Iceland. Iceland extends well over the whole ridge and allows for representative surface observations of sea-floor processes. Across the Peninsula the plate boundary is characterized by a rift zone, which encompasses leaky transform fault zone characteristics. LÄS MER
