LANDSAT and radar mapping of intrusive rocks in SE-Brazil [PDF]

The feasibility of intrusive rock mapping was investigated and criteria for regional geological mapping established at the scale of 1:500,00 in polycyclic and polymetamorphic areas using the logic method of photointerpretation of LANDSAT imagery and ...

Automated sliding susceptibility mapping of rock slopes [PDF]

, 2004
International audienceWe present a suite of extensions for ARCVIEW GIS? (ESRI) that allows to map the spatial distribution of first-order mechanical slope-properties in hard rock terrain, e.g. for large slope areas like water reservoir slopes.

Feature extraction and classification of digital rock images via pre-trained convolutional neural network and unsupervised machine learning

Machine Learning: Science and Technology
Understanding the microstructure of porous media is crucial in various fields—particularly in petroleum engineering, hydrogeology, and materials science—because it directly influences the properties of porous materials and the behavior of fluids within ...

TopoRSNet: A Unique Approach to Maintaining Topological Features for Digital Rock Image Rescaling With Minimal Quality Degradation

Journal of Geophysical Research: Machine Learning and Computation
The composition, microstructure, and physical behavior of rock at the core‐to‐pore scale are commonly visualized and characterized using 3D X‐ray microcomputed tomography (micro‐CT). However, a key geophysical problem in micro‐CT rock characterization is

Electric properties of granitic rocks [PDF]

, 2010
The objective of this work is to clarify the role of water content on the charge trans- port mechanisms of different granitic rocks. The mineralogical content of the rocks will also be taken into account. From the electrical point of view these materials
