Geophysical modelling of the Catalan magnetic anomaly: study of the crustal structure of the Gulf of Lion margin - Case Study
As part of a research project (the OROGEN project, carried out jointly with TOTAL and INSU-CNRS), BRGM has drawn on datasets from the French Gravimetric Database and the French Airborne Geophysical Database to study and model the geological structure that causes the Catalan magnetic anomaly. The need One of the main aims of the OROGEN research project is to improve knowledge of the processes ...

Laver Rock Mechanics Pre-Feasibility Study - Case Study
Project Description Boliden is investigating the Laver low-grade copper deposit for potential future mining. The old Laver deposit was discovered in the 1930s, and was operated between 1938 and 1946. Mining was primarily conducted as small-scale underground mining, but a small open pit was also in operation at that time. The currently investigated deposit is of larger scale and with lower ...

Geophysical applications to solid waste analysis
Abstract: Case studies of regional landfills show that electromagnetic geophysical methods can accurately and inexpensively define boundaries and thickness of waste. Degradation of putrescible solid waste generates conductive leachate that can be imaged with a frequency-domain terrain conductivity meter. Terrain conductivity measurements can be modified through a simple algorithm based upon ...

USGS, NASA Study Finds Widespread Coastal Land Losses from Gulf Oil Spill
A new USGS-NASA study found widespread shoreline loss along heavily oiled areas of Louisiana's coast after the 2010 BP Deepwater Horizon oil spill and compared the erosion from the spill with coastal changes Hurricane Isaac caused in 2012. A pattern of dramatic, widespread shoreline loss along Louisiana’s coast caused by the 2010 BP Deepwater Horizon oil spill has been revealed by a ...

A GIS-based methodology to delineate aquifer recharge areas
A GIS-based methodology to delineate risk areas for contamination of groundwater resources is presented by identifying recharge conditions to the aquifer. Identifying the recharge areas is based upon surface and subsurface geologic conditions that may control the risk of potential oil spill contaminants into the aquifer. This study uses the Chicot aquifer system in southwest Louisiana as a pilot ...

Unexploded ordinance case study
Jacksonville, Florida A geophysical investigation was conducted at a World War II era bombing range in the eastern United States. The site was approximately 2,000 feet by 300 feet in plan dimension. Historical information indicated that MK23 practice bombs, 2.75” rockets, and 100 pound practice bombs were used at the site. The purpose of the geophysical investigation was to determine the ...
