Dear everyone,
I recently interpreting the ERT data of an iron mine. The orange colour zone are predicted to be hematite rich zone (based on the resistivity and chargeability values). The type of iron mine is gossan / iron cap.
However, there are some abrupt transition of the resistivity reading (vertically changes as you can see in the profile), which my colleage suspects that is a fault. I am not very agree with his opinion however his aswer could be correct.
Therefore would like your eyes to see if there is any fault.
Thank you in advance for joining this open discussion.
Hello, Ong!
Maybe it's late to answer you but because i investigate fault zones using ERT it is interesting for me. Based on my experience fault zone has lower resistivity than enclosing rocks and it is often vertical ot subvertical. I just don't see zones like this in your diagram.
But on the other hand if there is an ore there should be fault zones. Borehole or geological data could help to determine faults.
