Magnetotransport Measurements of Ni Thin Films

In this report, we offer transverse magnetoresistance (MR) and Hall resistivity measurements of nickel thin films at temperatures between 280 and 455 K and pressures up to 6 GPa. A new system was developed for carrying out precise magnetotransport measurements making use

The Holocene Spread of Spruce in Scandinavia

The Holocene spread of Picea abies in Scandinavia provides an excellent opportunity for detailed study of the dynamics of tree spread and population expansion. Early- and mid-Holocene macrofossil evidence for the presence of Picea abies in Scandinavia has questioned traditional interpretations of the timing and direction of its spread.

Conceptual runoff models – fiction or representation of reality?

The South Portuguese Zone (SPZ), which host world-class massive sulphide deposits, forms the southern fold-and-thrust belt of the Iberian Variscan orogeny. This thesis focuses on seismic-reflection and seismic-refraction processing efforts on a subset of the IBERSEIS deep seismic-reflection data set aiming at resolving the SPZ upper crust in high resolution.

Kinematics and Deformation History of the Cross Lake Greenstone Belt

Greenstone belts are a common feature of Archean terrains. However, the tectonic environment for Archean earth remains in hot debate: did vertical or horizontal crustal movement dominate the Archean Eon? Small-scale structural analysis is applied to a late Archean greenstone belt in the Superior Province of the Canadian Shield in order to test the two end member hypotheses.

Examination of the Thermal Decomposition of Chrysotile

Project on Thermal Decomposition of Chrysotile. The splitting of pure chrysotile from Thetford, Quebec warmed up at constant temperature in air from 200-1000°C for 4 to 720 hrs has been investigated by making use of X-ray diffraction and optical microscopy methods. No morphological modifications had been observed optically below 450ºC and 24 hours, although X-ray diffraction data advise that chrysotile degrades then recrystallizes below 450°C.

Deformation zones in models and nature

Field studies encounter several complicating factors not studied in the models. Examples are oblique convergence, heterogeneous materials and thermal softening by intruding magmas. Within the deeply eroded Svecokarelian orogeny, studies in eastern Bergslagen indicate strain accommodation of the N-S orogenic shortening by
