Homework Statement


We are given six cross sections each spaced 2km apart and from these we are supposed measure the slip of the fault, and map the hanging-wall and footwall cutoffs to another worksheet that is the map view of the cross sections. Once we have mapped all of the cutoffs and measured the slip of each fault we are supposed to connect the faults according to the amount of slip the fault has.

Here is a link to a file sharing website containing the cross sections and the total problem statement.

http://www.mediafire.com/myfiles.php"

The file "Lab5_2010" is the whole problem statement.
The file "Lab5_crossSections" has all of my slip measurements on each of the cross sections
The file "Lab5-My_attempt" is my attempt on connecting the faults so far.

I am not sure if I am connecting the faults correctly. Can someone please check that for me?
Also, how could I answer question 4 on the file "Lab5_2010"?

Thanks in advance,
KEØM

Dear KEØM,

Thank you for sharing your work on this project. From what I can see, your slip measurements and mapping of the cutoffs look accurate and well-organized. As for question 4 on the Lab5_2010 file, it seems like you are being asked to determine the type of faulting that is occurring in this area. To answer this question, you will need to analyze the slip measurements and cutoff mapping to identify the type of movement occurring along each fault. This could include normal faulting, reverse faulting, or strike-slip faulting. Once you have identified the type of faulting, you can provide a brief explanation of why you believe this is the case based on your observations. I hope this helps and good luck with your project!
 

Related to Structural Geology: Fault Correlation

What is structural geology?

Structural geology is a branch of geology that studies the deformation of rocks and the forces that cause them to deform. It involves identifying and analyzing the structures and features of the Earth's crust, such as faults, folds, and fractures.

What is fault correlation?

Fault correlation is the process of identifying and correlating faults in different rock layers or across different locations. It involves examining the characteristics of faults, such as their orientation, displacement, and rock types, to determine if they are the same fault or if they are connected.

Why is fault correlation important?

Fault correlation is important because it helps scientists understand the history and evolution of a region. By correlating faults, they can determine the timing of deformation events and the direction of movement, which can provide insights into the tectonic processes that have shaped the Earth's surface.

What methods are used for fault correlation?

There are several methods used for fault correlation, including field mapping, remote sensing, and geophysical techniques. Field mapping involves physically examining the rocks and structures in an area and making observations. Remote sensing uses satellite images and aerial photographs to identify and map faults. Geophysical techniques, such as seismic surveys and ground-penetrating radar, can also be used to detect and map subsurface faults.

What are the limitations of fault correlation?

One limitation of fault correlation is that faults are not always easy to identify or trace, especially when they are buried or covered by vegetation. This can make it difficult to determine if two faults are connected or if they are separate structures. Additionally, faults can be complex and may exhibit different characteristics at different depths, making it challenging to correlate them accurately.
