Fractures, such as joints, faults and veins, strongly influence the transport of fluids through rocks by either enhancing or inhibiting flow. Techniques used for the automatic detection of lineaments from satellite images and aerial photographs, LIDAR technologies and borehole televiewers significantly enhanced data acquisition. The analysis of such data is often performed manually or with diff...

Time-averaged series of granulation images are analysed using COLIBRI, a purpose-adapted version of a code originally developed to detect straight or curvilinear features in aerospace images. The algorithm of image processing utilises a nonparametric statistical criterion that identifies a straight-line segment as a linear feature (lineament) if the photospheric brightness at a certain distance...

[1] We analyze data from continuous GPS stations in the southwes te rn Uni ted Sta tes and present the f i r s t observations of a systematic motion of the Colorado Plateau region. Relative to a North America‐fixed reference frame, westward velocities increase rapidly across the Wasatch fault system, which comprises the plateau’s northwestern margin, but increase more gradually between the Grea...

For the sustainable use of groundwater, this study analyzed groundwater productivity-potential using a decision-tree approach in a geographic information system (GIS) in Boryeong and Pohang cities, Korea. The model was based on the relationship between groundwater-productivity data, including specific capacity (SPC), and its related hydrogeological factors. SPC data which is measured and calcul...

In this paper, we have proposed the implementation of Groundwater Possibility Retrieval System to detect the groundwater possibility using the burgeoning technique of Biogeography Based Optimization and Case based reasoning retrieval. In the case base used in this study, Geology, Land form, Soil, Land use, Slope and Lineament play a decisive role in determining ground water possibilities. These...

Samples dredged from the Cruzeiro do Sul Lineament exhibit ferromanganese crusts precipitated above phosphate-rich substrates (phosphorites, phosphate-impregnated volcanic rocks and older phosphatized crusts). Co-chronology of crusts, paleontological data 87Sr/86Sr ratios substrate indicate that last phosphatization event in region happened between 17.6 14.6 Ma ago. When ceased, oxic conditions...

Geological lineaments are linear or curvilinear surfaces that considered a superficial expression of discontinuities on the earth’s surface. The extraction from remotely sensed satellite data is one most frequently used applications remote sensing in geology. This study focuses semi-automatic Girón–Santa Isabel basin using Topographic Position Index (TPI). were extracted PCI Geomatics 2016 soft...
