Correlation of magnetic fabric and crystallographic preferred orientations of naturally deformed carbonate — mica rocks from the Alpi Apuane in Italy and the Damara Orogen in Namibia
Otto, Michael; Hirt, Ann M.; Leiss, Bernd; Schmidt, Volkmar; Walter, Jens M. (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The anisotropy of magnetic susceptibility (AMS) is a time-efficient method to describe crystallographic preferred orientations of rocks and has been applied in a wide field of sedimentary, metamorphic and magmatic geology. ... -
Magnetic fabric in ilmeniterich norites of the Bjerkreimer-Sokndal Layered Intrusion, Norway
Hirt, Ann M.; Schmidt, Volkmar; McEnroe, Suzanne; Heidelbach, Florian; Robinson, Peter (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The Bjerkreim-Sokndal (BKS) is a layered intrusion, located in the Mid- Proterozoic Egersund anorthosite-norite province within the Sveconorwegian province of the Baltic Shield, south Norway. The layered intrusion formed ... -
Measurement of calcite crystallographic-preferred orientations by magnetic anisotropy and comparison to diffraction methods
Schmidt, Volkmar; Hirt, Ann M.; Burlini, Luigi; Leiss, Bernd; Walter, Jens M. (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The anisotropy of magnetic susceptibility (AMS) of rocks reflects the preferred orientations of minerals. Therefore AMS is a quick and easy way to characterize rock fabrics (Hrouda 1982,Borradaile 1988); the obtained result ... -
Separation of magnetic subfabrics by high-field, lowtemperature torque measurements
Schmidt, Volkmar; Hirt, Ann M.; Rosselli, Pascal (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The anisotropy of magnetic susceptibility (AMS) can serve as a good indicator of strain in deformed carbonate rocks with diamagnetic susceptibility (Owens and Rutter 1978; de Wall 2000). However, the magnetic fabric due ...
