Abstract Cross sections carry information on the spatial distribution of rock strata and development geological structures, it is an important data source for three-dimensional (3D) modeling. However, interpretation mapping structures in by means manual are inefficient costly, performance varies greatly with experts’ ability experience. The objective this article to develop automatic recognitio...

This paper presents results of previous investigations involving 1D and 2D resistivity imaging linear geological structures with varying traverse orientations relative to the structure azimuth a view determining effect such variation on resolution structures. It observed that orientation fault significantly determines while alignment vertical electrical sounding (VES) defines form VES curve lea...

1. introduction the earth's crust is composed of various landforms. these forms are constantly changing. in this change, both of internal and external factors have a decisive role. the internal factors led to the formation of the primary structure and external factors that cause erosion, deformation and destruction of these forms. areas that have been affected by these activities confronted by ...

various geological units in an area often exhibit different magnetic properties. due to this distinction in magnetic properties of the geological units, a correlation between the type of a geological unit and its magnetic response can be established. to determine the lateral and vertical extents of geological units from the magnetic data in a survey area, a number of filters for processing magn...

Detailed information about geology, hydrogeology and seismic hazard issues for Umbria region are contained in a spatial database available as open data format (shapefile or KMZ) and distributed under the regional open data portal called Open Data Umbria ( http://dati.umbria.it ) where 297 datasets have been produced by Umbria Region until now and most of them are made by Geological Survey. Geol...

Marine geological maps of the Campania region have been constructed both to a 1:25.000 and 1:10.000 scale in frame research projects financed by Italian National Geological Survey, focusing, particular, on Gulf Naples (Southern Tyrrhenian Sea), complex volcanic area where sedimentary processes strongly interacted during Late Quaternary Cilento Promontory offshore. In this paper, examples sheets...

The high hillsides of the Tehran metropolis are prone to landslides due to the climatic conditions and the geological, geomorphologicalcharacteristics of the region. Therefore, it is vitally important that a landslide susceptibility map of the region be prepared. For thispurpose, thematic layers including landslide inventory, lithology, slope, aspect, curvature, distance to stream, distance to ...

Magnetic instruments such as cross-wing gradiometers, vertical gradiometers and full tensor SQUID magnetometers presented challenges for geological interpretation and geophysical inversion. In particular, the full tensor magnetometer presents many new challenges for an interpreter where only the vertical derivative of the vertical magnetic component presents a useful geological analogue for vis...
