How To Draw A Cross Section Geology
Begin by choosing two points that define a cross section profile of interest.
How to draw a cross section geology. First you need to define topographic sources. Draw a cross section line on your map you can also import it as shapefile in place where you would like to model the geology. Decide what the geologic cross section is going to be used for and use this to guide you in selecting the appropriate.
Geologists will label this cross section line using letter designations such as a a. I walk you through the proces. These should be selected so that a line between them will be approximately perpendicular to the strike directions of the intervening rock units.
Now you can draw simple profile based on your section location and elevation data from dem. After that select your dem as a source of the profile. Choose appropriate vertical and horizontal scales.
In this video i teach you the process of creating drawing constructing whatever you want to call it a geologic cross section. Once you choose the area for your cross section draw that line on the topographic map using a ruler. On the map locate the well or borehole positions land service elevations depth of the well and the number of geologic.
There are four steps when drawing a cross section. Label these points as a and a. Put a strip of paper along the cross section and make a mark on your paper wherever the contour lines intersect with your paper.
