Susan has worked for GSB Prospection since her Doctorate graduation and is the company's Senior Geophysicist. This case study shows the advantages of the simultaneous use of both techniques (ERT and IP), over their individual application, in locating thin vein structures of metal sulphides embedded in Palaeozoic materials underlying a sedimentary cover. Exploration geophysics is the practical application of physical methods (such as seismic, gravitational, magnetic, electrical and electromagnetic) to measure the physical properties of rocks, and in particular, to detect the measurable physical differences between rocks that contain ore deposits or hydrocarbons and those without. Using electrical methods, one may measure potentials, currents, and electromagnetic fields that occur naturally or are introduced artificially in the ground. Since many of the standard data augmentation techniques lack a geophysical motivation, we have instead perturbed our synthetic training data in ways to make more sense from . The equipment employed for both techniques is very similar and assure the travel time of acoustic waves propagating through the subsurface. Introduction to Geophysical Prospecting. Some mathematical identities, 6 5.

Seismic surveying is the most important of the three main types of geophysical prospecting. The geophysical remote sensing surveys were conducted by sampling at regular intervals along consistently spaced parallel transects. The non-uniqueness of these solutions is both a mathematical problem and one related to the multiplicity of sources that can cause geophysical anomalies. The prospecting is repeated many times from The studies start with aerial observations and photography of large areas of land. Lecture 1. (b) Electro-magnetic. In oil prospecting structural Her knowledge of geological prospecting has led Susan to specialise in non-archaeological aspects of shallow prospecting and more recently on the use of GPR in archaeological investigations.
