Remote sensing technology is widely used in the application of extraction lineaments geological research. However, most current traditional lineament methods are based on edge detection using a digital filter to extract mitochondrial features image. These previously algorithms generally unable shadow area mountain and parallel direction solar incident angle. In this paper, we have improved STA ...

The Precambrian metamorphic rocks in the southern region of Espírito Santo State(southeastern Brazil) is intercepted by ductile and brittle/ductile shear zones over which towns like Guaçuí, Marechal Floriano Domingos Martins were established. In years 2014 to 2016 State faced worst drought past 80 years. situations that, only source fresh water available underground. Therefore, purpose this stu...

Quiescent faults may be capable of creating catastrophic earthquakes in locations with moderate and/or low seismic activity, such as Egypt. This study combines structural, remote sensing (RS), geophysical, and activity data to examine analyze the relationship between tectonic structures seismotectonic In a new seismo-lineaments map Egypt, lineaments Egyptian mainland were delineated classified....

Geological mapping undoubtedly plays an important role in several studies and remote sensing data are of great significance geological mapping, particularly poorly mapped areas situated inaccessible regions. In the present study, Principal Component Analysis (PCA), Band Rationing (BR) Minimum Noise Fraction (MNF) algorithms applied to map lithological units extract lineaments Amezri-Amassine ar...

This article aims to aid in exploring and forecasting hydrothermal minerals gold deposits Central Saudi Arabia (SA), with a focus on structural contexts. Remote sensing (RS) satellite-based Bouguer gravity (SBG) data were integrated order create mineral prediction map for the researched location. Data from Landsat Operational Land Imager (OLI) Shuttle Radar Topography Mission (SRTM) transformed...

Local earthquake tomography has been carried out in the Tjörnes Fracture Zone. This transform region connects Mid-Atlantic Ridge to Northern Volcanic Zone Iceland a mostly offshore area. The challenge record seismic information this area was motivation for North ICeland Experiment (NICE). Fourteen ocean-bottom seismometers and eleven on-land stations were installed project operated simultaneous...

Productive regions in the Crystalline Basement Aquifer System (CBAS) Paraná state, Brazil, were identified qualitatively and quantitatively through spatial correlation of wells geological conditions such as lineaments, hydrography, aeromagnetometry lithology. Different methods applied Precambrian metamorphic igneous aquifers around world some Brazilian states integrated CBAS with aim understand...

The entropy of shortest distance (ESD) between geographic elements (“elliptical intrusions”, “lineaments”, “points”) on a map, or between "vugs", "fractures" and "pores" in the macroor microscopic images of triple porosity naturally fractured vuggy carbonates provides a powerful new tool for the digital processing, analysis, classification and space/time distribution prognostic of mineral resou...

A modelling of the observed macroseismic intensity of historical and instrumental earthquakes in southern Spain is proposed, with the aim of determining the macroseismic parameters for seismic hazard evaluation in a region in which the characterization of intensity distribution of seismic events shows different levels of difficulty referable to the complex faults system of the area in study. Th...

[1] We examine the relationship between altimetric gravity and abyssal hill textures along the flanks of Southeast Indian Ridge, where previous studies observed a progressive west-to-east increase in abyssal hill roughness and scales. Such a relationship is often considered unlikely because abyssal hills are typically smaller than upward continuation filter scales. However, our results, which e...
