Scott Hogg & Associates Ltd. have completed the development of a 3-axis, helicopter towed, aeromagnetic gradiometer. The towed bird is a complete airborne system with 4 cesium sensors, radar altimeter, pitch, roll and yaw measurement, a 3-axis magnetic fluxgate and a GPS positioning system. The system is designed to provide accurate geo-referenced magnetic gradients; G-east, G-north and Gvertic...

One of the most prominent features on gravity and aeromagnetic maps of the United States is a series of major, generally linear anomalies that extend from central Kansas to Lake Superior and then turn southward into central Michigan (Figures 1, 2). This system of anomalies clearly reflects major geological features, and as such it must represent a very significant episode in the history of the ...

By analysing potential field data in the wavelet domain and performing a multi scale edge detection we can automate what in geologic jargon is commonly called 'worm analysis', i.e., the traditional visual inspection of gravity and aeromagnetic data in order to detect shallow faults, lineaments, contacts etc. More importantly, with the use of an appropriate wavelet, defined by the physics of the...

Abstract One of the main goals interpretation magnetic data is imaging boundaries subsurface structures. In this study, a new edge detector called improved horizontal tilt angle (impTDX) has been introduced and tested on synthetic measured data. The filter exhibits high efficiency not only in detecting sources, but also determining sources from different depth levels. impTDX produces more preci...

Incomplete and sparse information can introduce a high level of risk for oil exploration and development projects. “Expert” systems developed and used in several disciplines and industries have demonstrated beneficial results in modeling the decision making process of knowledgeable experts. A state-of-the-art exploration “expert” tool using a computerized data base and computer maps generated b...

The study area includes an between 6° to 8°N and 11° 15°E. Geologically, it belongs Precambrian basement (granites, gneisses), Proterozoic, Archean (volcanic) series, showing the main heat sources of Cameroon. purpose this deals analyze interpret EMAG2 magnetic data in Adamawa using various advanced processing techniques. Thus, mapping depth estimation underground structures are realized. analy...
