Three case studies have been selected to help illustrate the many ways constructing cross sections have helped understand a basin, avoid drilling dry holes (or explained why a dry hole was dry), added reserves to a field, or have helped define new plays and opportunities. It is primarily used in the study of sedimentary & layered volcanic rocks. On sections oblique to strike, the cross . ConcepTest: Cross Section Explanation. Instructions to Construct a Geologic Cross Section at Woburn There are several steps involved in making a geologic cross section from geologic logs, as described below and in the Reference Book. Key Bed Baked Zone An intrusive rock with a baked zone is younger than the rock it intrudes 6. Variations in this surface are depicted on maps as contoured elevation data or graduated raster images (with colour scales . Monitoring cross sections are most beneficial if located along the reconfigured channel in areas most sensitive to alteration by streamflow; for example, in areas that might scour or aggrade as bed material is transported, or in meander bends where lateral erosion could occur. A vertical cross-section showing the trace of a geologic surface may be constructed in exactly the same way by noting where structure contours cross the line of section. The meaning of CROSS SECTION is a cutting or piece of something cut off at right angles to an axis; also : a representation of such a cutting. Due to the age of this map, these images do not necessarily represent an accurate interpretation of currently accepted geologic theory.

Geological cross section is a graphical representation of a vertical slice through the earth used to clarify or interpret geologi-cal relationships with or without accompanying maps. You also used your cross sections to quantify the amount of brittle deformation by measuring the offset across faults. Two examples of geologic structures are . Geologists almost always draw cross sections from maps and not the reverse. In effect, it is a map of the geology as a prehistoric geologist would have recorded it just before renewed deposition began to bury the ancient erosion surface. Created with funding from NSF CCLI Award #0087894. Key Bed ~6000'. A cross-section is not a geologic map. This is an example of a relative age diagram. Geologic cross section E-E' is the first in a series of cross sections planned by the U.S. Geological Survey (USGS) to document and improve understanding of the geologic framework and petroleum systems of the Appalachian basin. Contour lines: These help in drawing topographic profile along the line of section. lab in JCMB (room 6307). Once you have a cross section line created (see example below) You may click on the button, which is the Show/Create Cross Section button and allows a cross section corresponding to a selected cross section line on the map to be created or viewed. These skills are often not focused on in undergraduate geoscience curricula and many students struggle with spatial relations, manipulations, and penetrative . Monitoring cross sections are most beneficial if located along the reconfigured channel in areas most sensitive to alteration by streamflow; for example, in areas that might scour or aggrade as bed material is transported, or in meander bends where lateral erosion could occur. This could be the area you plan to hike or as in this example here, a line through the highest part of the mountain so that we can get a really good visual of the mountain's elevation. section - KINK method - Structural Geology 2015 GL2 geological map and cross section Constructing Cross Sections 3 Point Problems, Strike Lines, and Apparent Dip Relative Dating - Example 1 Topographic Profiles and Gradient "Balanced" refers to the basic assumption made in constructing these sections .
