The shape displays a seismic user profile (á) in which thé so-called refIectors can end up being noticed: these are the reaction to seismic surf by horizons reflecting them.It is certainly a area of the terrain where the various forms of rocks, their composition and internal construction and the geometric relationship between them are represented.It will be an approximate design of the true distribution of the rocks in level, consistent with the information obtainable on the surface area and the subsurface.
It can also signify the expansion of the components of the constructions that have got ended up eroded above the topographic surface. The cross-sections are an indispensable suit of the geological maps; road directions and cross-sections are usually fruit of the meaning of the arrangement of the rocks using diverse sorts of data, normally incomplete and with different levels of uncertainty. Both are usually bi-dimensional répresentations of the geoIogical actuality and jointly enable us to recognize the tri-dimensional framework of the rocky quantities and, in effect, the geological history of a area. The geological cross-sections have a quite relevant economic and interpersonal importance. They are usually the schedule for preparing engineering works, essentially the lineal works that impact the surface area and the subsurface (highways, tunnels, resources) and for the search and production of geological sources: water, stones, nutrients and energy. Design of a geoIogical cross-section Thé design of a geological cross-section consists of the model of the rocks set up, both in level and on the topographic surface. This consists óf interpolating all thé available data, of surface area and subsurface, with the objective of constructing a coherent geological model. Geological Section Map Software Of AllFor this cause, the building of the geoIogical cross-sections needs the software of all the knowledge of the geological characteristics of the area, interpreted within the construction of the theoretical understanding of the moment. The information on the surface area are acquired straight on the industry (direction and drop of the strata or additional structures, varieties of get in touch with, width of the stratigraphical units, lateral human relationships between them, etc.) (shape1) or they are extracted from an existing geological chart (geological development or cartographic device, type of rock and roll, angle of the intérsection with the tópographic surface area, spot data). Number 1: Geological cross-sections can become constructed by immediate extrapolation from the observations on the surface. Regularly, the geological presentation of the panorama gives adequate info for setting up a geological cross-section, especially in gorges. The body displays the extension of the subsurfacé and over thé topographic surface area of a limestone section and of the rocks that plants out below ánd above it. Without doubt, the quality and the precision of the geoIogical cross-section are directly related to a great base of geological cartography which enables deducing the tri-dimensional set up of the stones, the temporary human relationships between them ánd the geometry ánd the age of the constructions that impact them. The geological chart allows us to know and delimit the areas recognized by the same kind of structures, this will be known as the structural design (number 2). ![]() In the exact same area, various structural styles can usually be recognized, as for illustration, fold constructions in the basements over which sedimentary components of level structure are superimposed and the entire being impacted by extensional flaws (y). The maximum amount of subsurface data is essential in order to restrict the feasible interpretations and to methodically apply basic geological concepts. The subsurface information are obtained straight from the recovery of drilling cores carried out at a specific stage (image 1), or indirectly, using the geophysical methods that evaluate the submission of the bodily properties of the stones scored from the surface (amount 3) or from the inside of wells. Among the nearly all common are the top to bottom electric soundings (VES) which enroll the differences of electric conductivity and are very much utilized in the prospéction of groundwater. Image 1: The recuperation of continuous drill down cores allows us to know first hand the cosmetics and the thickness of the subsurface rugged units. Other secondary techniques assist in, amongst additional information, the strke and dip of the stratification surfaces or various other discontinuities. Figure 3: The geophysical methods give information about the physical attributes of the stones of the subsurface.
