Abstract [en]

This bachelor thesis has been produced as a project preparation for an MFS project during the autumn of 2014 on Fogo, Cape Verde. The long term aim for the MFS project is to conduct a geological survey on Fogo, gather geological information and assess the magma storage depth for future geothermal applications. Understanding the mechanisms of ocean island volcanism, magma feeding behavior and requirements for geothermal energy is essential for the future survey. Previous geological surveys done on Fogo are few in numbers and are primarily focused on slope stability, volcanic features or geophysical surveys, focusing on mantle plume depth. By describing rock samples from Fogo and understanding what environment the rock samples have formed in, a more accurate description of the volcanism at present can be produced. For this project we described 11 rock samples and 9 thin sections from Fogo, in terms of the samples; mineralogical composition, colour, structure, texture, matrix, phenocrysts and alteration features. By merging the rock descriptions with a previously produced geological map, we produced two digital maps with geological information. One displays Fogo on a larger scale with correlated localities of representative rock samples. The maps will be used during the field work during 2014 when additional implementations to the maps will be made.
