Measurements of structure orientations are afflicted with uncertainties which arise from many sources. Commonly, such uncertainties involve instrument imprecision, external disturbances and human factors. The aggregated uncertainty depends on the uncertainty of each of the sources. The orientation of an object measured in a borehole (e.g. a fracture) is calculated using four parameters: the bea...

Abstract. The restrictions implemented to contain the spread of COVID-19 pandemic during 2020 and 2021 have forced university-level educators from around world seek alternatives residential physical field trips that constitute a fundamental pillar Geoscience programmes. field-mapping course for second-year Geology BSc students Cardiff University was replaced with virtual mapping set in same are...

Purpose. Discontinuities in rock masses are natural fractures that delimit various block shapes and sizes, which can fall, slide or topple from the excavation collapse under their own weight inducing probably severe damage. Thus, it is essential to carry out a analysis before beginning any surface underground project. This paper proposes methodology based on key theory select suitable slope of ...

This study wants to give a contribution the semi-automatic evaluation of rock mass discontinuities, orientation and spacing, as important parameters used in Engineering. In complex inaccessible areas, traditional geological survey is hard conduct, therefore, remote sensing techniques have proven be very useful tool for discontinuity analysis. However, critical expert judgment necessary make rel...

Abstract. We present two original, video-game-style field geology experiences designed to allow flexible, open-ended exploration for geologic mapping and structural geology. One simulation features the Whaleback anticline, a site in central Pennsylvania (USA), with three-dimensional exposure of 30 m high fold, based on terrain model that was acquired through structure-from-motion photogrammetry...

Complex geomagnetic and tectonophysical studies were performed in order to characterize detail the heterogeneity of Earth’s crust Zvenyhorod-Bratskfault zone clarify its internal structure kinematics. Based on results magnetometric studies, maps different wavelength components magnetic anomalies obtained, sources which are associated with layers crust; magnetization upper, middle lower parts wa...

The uniaxial compressive strength (UCS) of intact rocks is one of the key parameters in the course of site characterizations. The isotropy/anisotropy condition of the UCS of intact rocks is dependent on the internal structure of the rocks. The rocks with a random grain structure exhibit an isotropic behavior. However, the rocks with a linear/planar grain structure generally behave transversely-...
