How To Draw Geological Cross Sections
On the map locate the well or borehole positions land service elevations depth of the well and the number of geologic.
How to draw geological cross sections. Index note readings 8 7cms and 13 8cms have been ass. To construct a geologic cross section first take a geologic map of the target survey area. These should be selected so that a line between them will be approximately perpendicular to the strike directions of the intervening rock units.
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. How to measure the dip angles convert scale draw strike lines plot the section on the journal. Set minimum z value to 0 as we will need space for geological interpretation.
Take a thin strip of paper and place it along the cross section line. Choose appropriate vertical and horizontal scales. Where the contours intersect with the.
Now you can draw simple profile based on your section location and elevation data from dem. Decide what the geologic cross section is going to be used for and use this to guide you in selecting the appropriate. Label these points as a and a.
