Airborne magnetic and radiometry data sets over potential gold mineralisation associated with mesothermal alteration zones in the western Ilesha schist belt, Southwestern Nigeria, were interpreted. This was done to provide information on possible extent of geologic transformations that accompanied area. Interpreted gamma spectrometric successfully used delineating hydrothermal potassium K enric...
The first images of the asteroid 243 Ida from Galileo show an irregular object measuring 56-kilometers by 24 kilometers by 21 kilometers. Its surface is rich in geologic features, including systems of grooves, blocks, chutes, albedo features, crater chains, and a full range of crater morphologies. The largest blocks may be distributed nonuniformly across the surface; lineaments and dark-floored...
The Hough transform is an established tool for discovering linear features in images. The present investigation presents a new and specific algorithm for detecting geological lineaments in satellite images and scanned aerial photographs which incorporates the Hough transform, a new kind of a "directional detector," and a special counting mechanism for detecting peaks in the Hough plane. Three t...
In Cameroon in general and the Highlands of Cameroon particular, there is no fracture map since its realization not easy. The region’s harsh accessibility climatic conditions make it difficult to carry out geological prospecting field missions that require large investments. This study proposes a semi-automatic lineament mapping approach to facilitate elaboration of West Highlands. It use...
Abstract In this paper, a new way of characterizing the mining-driven complex geological deformations is presented by utilizing continuous real-time microseismic (MS) data acquired through passive seismological monitoring. The was processed, and source parameters were computed encompassing over 60,000 MS events. correlation between events regional stratigraphy reveals that Upper Middle Xishanya...
The network of fault zones caused by vertical and horizontal tectonic displacements blocks Earth’s crust relative to each other is clearly visible on the surface in images obtained from satellite surveys. Many researchers distinguish linear annular structures among faults. Lineaments are detected as rectilinear objects with a certain spectral brightness. initial data for experimental research i...
