Sistemas filonianos multifractales en la Península Hurd, Isla Livingston, Antártida Occidental

Abstract

Analysis of vein systems has been carried out in eleven traverses along the coastal area on Hurd Peninsula, Livingston Island (South Shetland Islands, Western Antarctica), to characterise vein geometry using fractal and multifractal analysis techniques. Vein thicknesses generally conform to a power law distribution of the form N(k C t D, where Nt is the number of veins with a thickness > t. This may be interpreted in terms of scale-invariant (self-affine fractal scaling of vein geometry) which has been verified to several orders of magnitude. Multifractal analysis of vein networks has been applied using the capacity dimension (D J, the information dimension (Dt) and the correlation dimension (D ,) to measure the heterogeneity, dimensionality and connectivity of the fracture systems.
