An investigation into the controls of granite plutonism in the Sierra da Freita region, Northern Portugal [PDF]

open access: yes, 2012
The Serra da Freita region of north central Portugal was chosen for study as it displays the complex relationships between regional structure, plutonism, regional and contact metamorphism typical of this part of Iberia.

Elastoplastic finite element simulation of domino fault formation associated with tilting of highly structured ground

open access: yesSoils and Foundations
Ground deformation on the Earth’s surface layer is strongly affected by the nonlinearity of geomaterials. However, the formation process of such deformation has yet to be described in a unified manner based on mechanics.
