Vimy Ridge and Geophysics

Don Gendzwill

…Vimy Ridge in northern France, a heavily fortified German army stronghold since 1914, was thought to be impregnable after large French and British armies suffered heavy losses in 1915 and 1916 in attempts to re-capture it. Many of the losses were due to their own inaccurate artillery fire. During April…

The wedge model revisited

Joanna Cooper, Don Lawton and Gary Margrave

…Abstract Several physical seismic models of simple wedges were built to assess amplitude effects commonly associated with the classic ‘Widess’ wedge. Rather than producing simple tuning associated with thin beds, 2D zero-offset seismic surveys over these physical models showed a surprising number of high-amplitude dipping events corresponding to pure-mode ,…

2-D Migration Footprint

Peter Cary

…It is sometimes thought that prestack migration footprint is a 3-D problem that is due to the poor spatial sampling inherent in prestack 3-D data. Footprint is often visible on 3-D time slices as a hatched interference pattern, as in Figure 1. However, it is not always recognized that prestack…

Improved trending of features on aeromagnetic maps

Richard Smith and Michael O’Connell

…Summary In mining and near-surface geophysics, aeromagnetic maps are an important tool for mapping geology. In some terrains, the geology is comprised of narrow features striking at multiple angles. When the aeromagnetic data is converted to a grid, these features do not always image well, particularly when the features are…

Mapping the Mantle Lithosphere for Diamond Potential

David Snyder, Michael Bostock and Grant Lockhart

…Introduction Diamond deposits are typically identified in four stages: (1) regional targeting in which a region’s potential is assessed, often by grid till sampling for indicator minerals or global seismology; (2) kimberlite detection in which till sampling and high resolution aeromagnetic surveys locate individual deposits; (3) deposit delineation in which…

The Influence of the Lithosphere on the Core: 3D Mantle Convection Modelling on Planetary Scales

Julian P. Lowman and M. Hosein Shahnas

…Abstract Parallel computing clusters have made it feasible to study three-dimensional mantle convection on time scales of billions of years. Models tailored to take advantage of parallel machines are being used to re-examine problems where the full effects of three-dimensionality have remained unexplored. As a result, it has become possible…
