Quantitative analysis of geoscientific data to determine the areas most likely to contain mineral deposits is becoming increasingly common in the mining industry. The approach is based on characterising areas known to contain deposits and seeking similar areas elsewhere. This paper presents an automatic image processing technique for the prospectivity analysis of Archaean lode gold deposits, wh...

Geoscientists have extensively used machine learning for geological mapping and exploring the mineral prospect of a province. However, interpretation results becomes challenging due to complexity models. This study uses convolutional neural network (CNN) Shapley additive explanation (SHAP) estimate potential locations gold mineralisation in Rengali Province, tectonised mosaic volcano-sedimentar...

Lineament enhancement is an important subject in image,processing. In this paper a simple but powerful lineament enhancement technique is presented, which consists of a unique differentiation and a directional filtering. A preprocessing and postprocessings are also described. And some results from LANDSAT images are selected and exhibited for comparison of the effects of several parameters in e...

The remotely sensed data provides synoptic viewing and repetitive coverage for thematic mapping of natural resources. In the present study hydrogeomorphological mapping has been carried out in Ottanchattiram Block, Dindugal District, Tamil Nadu for delineating groundwater potential zones. Landsat ETM+ Geocoded FCC data in conjunction with Survey of India toposheet (1:50000 scale) were used for ...

Introduction: The mapping of lineaments from digital remote sensing data is one of the techniques used in the structural and tectonic characterization of a planet. Lineament mapping on Mars is traditionally made using digital imagery [1,2]. MOLA altimetry data was also used to the visual interpretation and extraction of tectonic features from Mars surface [3]. All these works rely on traditiona...

Frequency is a key physical parameter in potential field theory. Accordingly, Fourier transforms play an important role in aeromagnetic processing and many common enhancements are efficiently implemented in the Fourier domain. However, the trade-off for accurately measuring the frequency content of a signal is a complete absence of spatial localisation in the Fourier domain. Fourier-based enhan...

Introduction: The Sudbury impact structure is one of three large complex impact basins on Earth that provide unique opportunities to understand the structural characteristics of multi-ring impact basins [1]. The impact event formed ~1.85 Ga, resulting in a ~200 km diameter impact structure [2]. The structural expression at Sudbury is very complex with evidence of extensive post-impact tectonism...

This work introduces a new approach for modification of adaptive Lee algorithm for semautomatically detects geological features from RADARSAT-1 SAR data. This is based on modification of Lee algorithm formula by using 2D Gaussian convolution formula. The result shows that the new formula of Lee algorithm can be delineated lineament features in RADARSAT-1 SAR data. The new formula based on 2D Ga...

Introduction: The Near-Earth Asteroid Rendezvous NEAR-Shoemaker spacecraft orbited the asteroid 433Eros for a year from 2000-2001. The NEAR Multi-Spectral Imager (MSI) collected tens of thousands of high resolution images and as a result Eros is the most comprehensively studied asteroid in the solar system. Previous mapping of lineaments on Eros has supported the suggestion of planes throughout...

Lineaments are vital geological features that play the role of a key indicator for ground water and petroleum searching. At present, there is no study that has utilised remote sensing satellite data to reconstruct three dimensional (3-D) lineament visualization in the Uinted Arab Emirates (UAE). This work aimed at reconstructing a (3-D) lineament visualization from multispectral remote sensing ...
