Geologic Cross Sections
It also helps us to interpret the total geology of the map.
Geologic cross sections. A geologic cross section shows geologic features from the side view. The cross section of a geological map exposed all inner formations of rock beds. On the map locate the well or borehole positions land service elevations depth of the well and the number of geologic.
Geologic cross sections can assess temporal models of rock formation through time. The datumis the level or reference horizon from which elevations and depths are measured in the cross. A geological cross section is a graphic representation of the intersection of the geological bodies in the subsurface with a vertical plane of a certain orientation.
Geological modelling from cross sections british geological survey. Choose appropriate vertical and horizontal scales. Decide what the geologic cross section is going to be used for and use this to guide you in selecting the appropriate.
The resulting cross section is a cutaway image much like those seen in canyon walls or road cuts. Completed geological cross section in inkscape using the exported qprof colour palette. In order to construct a geologic cross section obey the following steps.
On the basis of the reading knowledge of a geological map we select the section line of the map and steep forward to drawing of the cross section. Since the geologic cross sections are meant to be done in only one period there are only three 3 for them to complete. The first one if fairly straightforward while the second and third cross sections are generally more complex.
See reflection in this section for more information on student groupings. Stratigraphic cross sections choice of datum. They are similar to the topographic profiles that you have already created but include additional information about the rocks present.
