An Exercise in Visual Correlation Using Gigapan Imagery

Side-by-side identical images of a small normal fault. Zoom in on a portion of the stratigraphy in the footwall in the left image and then zoom in on the same strata in the hanging wall on the right image. Adjust centering and zoom as necessary in order to visually correlate the strata from the opposite sides of the fault.



Same exercise as above, but this time with roadcuts on opposite sides of the road. Can you match the strata?



Same exercise as above, but this time with roadcuts from about 20 miles apart. Can you match the strata?
