Fabrics from Anisotropy of Magnetic Susceptibility (AMS) analyses and Shape Preferred Orientation (SPO) of plagioclase are compared with field structures (such as bridge structures, intrusive steps and magma lobes) formed during magma intrusion in Jurassic sills. This is to constrain magma flow directions in the sills of the Karoo Igneous Province along the KwaZulu-Natal North Coast and to show how...
Shape ellipsoids that define the petrofabrics of plagioclase in Jurassic Karoo dolerite sills in KwaZulu-Natal, South Africa are rigorously constrained using the long axis lengths of plagioclase crystals and ellipse incompatibility. This has been undertaken in order to determine the most effective technique to determine petrofabrics when using the SPO-2003 programme (Launeau and Robin, 2005). The...
Europa, the second Galilean moon of Jupiter, is composed of a silicate mantle and an ice shell which overlies a supposed subsurface ocean. The surface of Europa is scarred with fractures varying in morphology, dimensions, and geometry. We focus on Agenor Linea: a ∼1500km bright band that extends across Europa’s antijovian to trailing southern hemisphere. Agenor Linea is morphologically a band-like...
