Kimberlites associated with the Lucapa structure, Angola 

Robles Cruz, Sandra Elvira (Date of defense: 2012-12-12)

Six kimberlite pipes within the Lucapa structure in northeastern Angola have been investigated using major and trace element geochemistry of mantle xenoliths, macro- and megacrysts. Geothermobarometric ...

Multi-isotopic and statistical approaches to trace nitrate pollution sources and assess natural attenuation in groundwater: examples from nitrate vulnerable zones in Catalonia (NE Spain) 

Puig Caminal, Roger (Date of defense: 2014-05-19)

In the last decades, anthropogenic inputs of nitrogen to groundwater have dramatically increased, and they nowadays represent one of the most important water resources concerns as NO3-N has become the ...

Mineralogy and geochemistry of the platinum group elements (PGE), rare earth elements (REE) and scandium in nickel laterites 

Aiglsperger, Thomas Hans (Date of defense: 2015-12-17)
