I have difficulty understanding this. What it this geologist talking about and why does he think he found Bin Laden based on what the rocks looked like in the video?

You could apply the same principle here in the US. Rock formations in Northern Texas are far different from those in Southern Texas.

It's kind of like a geologic signature.

The article is fairly well written so I just assumed that anyone with an IQ above body temp. would have some understanding of this.

If the rock behind Bin Laden was sedimentary, it would suggest that the area was underwater at some recent point in its history. I suspect only southern Afghanistan is at a low enough elevation to have been under a sea in the recent past.

Any experts out there who can back that up or discredit my theory?

Not all rocks are alike. The rocks seen in the video are found only in certain regions. Like the White Cliffs of Dover. Nothing else like it.
