    Palaeozoic petroleum systems of the Murzuq Basin, Libya 

    Shalbak, Farid Ali (Date of defense: 2015-12-21)

    The Murzuq Basin is a sedimentary basin located SW Libya which geology remains poorly understood in spite that their proved reserves has been estimated up to 6000 MMb and a number of finds have been recently reported. The ...

    Paleobiología de los artrópodos del ámbar cretácico de El Soplao (Cantabria, España) = Arthropod paleobiology of the cretaceous amber from El Soplao (Cantabria, Spain) 

    Pérez de la Fuente, Ricardo (Date of defense: 2012-12-21)

    El yacimiento de ámbar de El Soplao (Rábago, Cantabria), de edad Cretácico Inferior (hace unos 110 millones de años), ha proporcionado a día de hoy más de 500 bioinclusiones de artrópodos. El estudio morfológico y sistemático ...

    Paleobiología de los escarabajos (Insecta: Coleoptera) de los ámbares cretácicos del oeste europeo 

    Peris Cerdán, David (Date of defense: 2015-11-27)

    Los coleópteros son en la actualidad el grupo biológico con mayor biodiversidad de la Tierra. Se conocen coleópteros fósiles desde el Pérmico, pero conservados en ámbar solo desde el Cretácico inferior. Este tipo de ...

    Paleogene Chronostratigraphy of the SE Margin of the Ebro Basin: Biochronological and Tectonosedimentary Evolution Implications (Cronostratigrafia del paleogen del marge SE de la conca de l’Ebre: Implicacions biocronològiques i evolució tectonosedimentaria) 

    Costa Gisbert, Elisenda (Date of defense: 2011-09-20)

    This PhD-Thesis presents a new chronostratigraphy of the Paleogene sedimentary record of the SE margin of the Eastern Ebro Basin. It is based on a number of magnetostratigraphic sections and its integration with marine and ...

    Population structure and spatio-temporal modelling of biological attributes and population dynamic of nylon shrimp (Heterocarpus reedi) off central Chile (25°-36°S) = Estructura poblacional y modelamiento espacio-temporal de los atributos biológicos y la dinámica poblacional del camarón nailon Heterocarpus reedi (Decapoda, Caridea) frente a Chile central (25°-36°S) 

    Canales, Cristian M. (Date of defense: 2016-10-25)

    The population structure of fishery resources and the impact of environmental factors over its productivity are important processes to be considered in fisheries management. Environmental factors could determine both, the ...

    Sedimentology and geochemistry of gas hydrate rich sediments from the Oregon margin (Ocean Drilling Program Leg 204) 

    Piñero Melgar, Elena (Date of defense: 2009-05-22)

    Gas hydrates have been recently recognized as a key factor affecting a number of global processes such as the climatic change, sea floor stability, etc. In this thesis we present the multidisciplinary study of gas hydrate ...

    Storfjorden Trough Mouth Fan (Western Barents Sea): slope failures in polar continental margins; significance of stress changes and fluid migration induced by glacial cycles 

    Llopart Serra, Jaume (Date of defense: 2016-11-22)

    The development of two Arctic Trough Mouth Fans (TMFs), the Storfjorden and Kveithola TMFs, is investigated by means of sub-bottom and seismic reflection profiles, multibeam bathymetry and sediment samples allowing their ...

    Ultra-high resolution environmental and climatic reconstruction using oxygen and carbon isotopes of diatom frustules 

    Hernández Hernández, Armand (Date of defense: 2010-09-21)

    Calcareous microfossils are not always present in marine or lacustrine sediments owing to unfavourable ecological or post-depositional conditions. These non-carbonated sediments sometimes contain abundant biogenic silica, ...
