G-46
If no exact answers can be given, I'd appreciate a clear explanation on how to do it. I really need all the help, thanks.
Problem 15.3 Use the bed-length technique to restore the cross section in Fig. G-45 and evaluate whether or not it balances. That is, draw the stratigraphic template for the restored cross section below the deformed cross section. Then measure the bed lengths of each unit from the pin line, and determine the positions of the ramps and flats of the future fault on the stratigraphic template. Be sure to measure both the top and bottom of each of the three layers; you will have six measurements in all. If the cross section does not balance, state specifically what is wrong with it and key your comments to the deformed-state cross sec tion. Identify every error; it is not sufficient to say "bed length too long."Explanation / Answer
For this, we need to identify the foreland and hinterland in this section.
Now we need to identify the transport direction of the flow in this I can see the flow is towards the Pin Line.
Now label each point where the trace of axial plane crosses a contact. This point will help us to determine the end point of the line segment.
Now reproduce it on different sheet
Start by restoring the youngest fault first, these are the fault closest to the fault closest to the foreland. You should start by restoring the fault closest to the pin line agents the transport direction.
Measure the line segment on the footwall on the youngest fault.
Now draw the line segment horizontally with the above-measured length.
Repeat for each line segment.
At the end, you’ll get the desired section to be restored.
