In the Bridge River mining camp the federal-provincial aeromagnetic maps, Tyaughton Lake (92Ji15) and Bridge River (92Ji16). at 1:63 360 scale, provide a ready base for analysis. Regional geological control is provided by current mapping and by the Geological Survey Branch (Open File Map 1987I I , Geology o j rhe Gold Bridge Area) and previous work by Leech (1953). Roddick and Hutchinson (1973)...

Abstract. Aeromagnetic exploration is an important method of geophysical exploration. We study the compensation towed bird system and establish interference model. Due to geomagnetic gradient changing greatly, considered in In this paper, we model field analyze influence on aeromagnetic results. Finally, apply ridge regression solve problem. verify feasibility through actual flight tests furthe...

The Samoan volcanic lineament has many features that are consistent with a plume-driven hotspot model, including the currently active submarine volcano Vailulu’u that anchors the eastern extremity. Proximity to the northern end of the Tonga trench, and the presence of voluminous young volcanism on what should be the oldest (~5 my) western island (Savai’i) has induced controversy regarding a sim...

S U M M A R Y Combining CHAMP satellite magnetic measurements with aeromagnetic and marine magnetic data, the global geomagnetic field has now been modelled to spherical harmonic degree 720. An important tool in field modelling is the geomagnetic power spectrum. It allows the comparison of field models estimated from different data sets and can be used to identify noise levels and systematic er...

1. To prepare various thematic layers such as drainage density, lineament density, slope, lithology, geomorphology and landuse/land cover using SOI topographical maps, remote sensing data and GIS. 2. To prioritize the weightages of individual themes and feature score depending upon their suitability to hold groundwater. 3. To prepare the integrated final groundwater potential map (GPM) using th...

By analysing potential field data in the wavelet domain and performing a multi scale edge detection we can automate what 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 problem, informati...

Recent advances in the research of autonomous vehicles have showed a vast range of applications, such as exploration, surveillance and environmental monitoring. Considering the mining industry, it is possible to use such vehicles in the prospection of minerals of commercial interest beneath the ground. However, tasks such as geophysical surveys are highly dependent on specific sensors, which mo...
