Our transcription: When geologists examined the features of Pakistan on a large scale, they were quite surprised.
There are a series of folds in Pakistan that look like you have kind of a wrinkle under your eye after you've been up too long.
The conclusion was that these really marked areas where we have thicker sequences of sediment; that is, these were old basins.
What we concluded was that we were really looking at a rather complex margin of an old continent.
The fact that the mosaic revealed features and relationships that had not been detected from the analysis of single images or from field investigations prompted geologists to seek answers to questions that might never have been asked.
And as we delved into the literature, we found that there was good evidence that, in fact, the Indian plate itself had grooved into Eurasia up on the northwestern corner and then rotated counterclockwise.
So insights like that become just absolutely invaluable in trying to unravel the deformational history that may bear on where hydrocarbons might be located today.
Well we were able to come up with a number of other areas that have not been examined that look like they have very, very large potential.
