Constructing a geologic cross section student assignment. Rock formations are readily observed in steep faces such as cliffs canyons and mountainsides in a kind of natural cross section. It is a section of the terrain where the different types of rocks their constitution and internal structure and the geometric relationship between them are represented. It is perhaps for this reason that cross sections seem more immediately familiar than geological maps and give a more striking picture of the arrangement of the beds.
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. Drawing a geologic cross section oregon state university ecampus. A structural cross section is made to show the shape of a geological structure so as to evaluate the relationship of fluid contacts and compartments to that structure. The resulting cross section is a cutaway image much like those seen in canyon walls or road cuts.
It provides scaled outputs of the cross section with field tests and soil profiles. Converting a topographic profile into a surface cross section part 2. 331 kb cross section of typikal terrase png 1 464 1 147. 107 kb cross section of sedimentary layers png 1 000 803.
Cross section of a subduction zone and back arc basin jpg 499 310. Creating and evaluating cross section is a very important aspect of the geoscience profession. While geologists may be able to infer such features from a plan view geologic map the addition of a cross section provides a third dimension of information that can greatly enhance the ability to evaluate folds and faults. Such features as spill points rollover on faults and fault geometry give an indication of the likely limits of field production.
The stratigraphy cross sections module is designed for easy creation of geological cross sections including lenses faults.
