Here's the geological deal - in uplift and plate tectonics, bits of the sea floor can be caught between the two plates and end up on top of mountains. The fact that Mt. Everest is made of marine limestone is perfectly logical - the Himalayas were formed by the collision of India with the Eurasian plate. Before this, there was a shallow sea in between them where limestone could easily form.
If this is true then there should be evidence in the Himalayas of severe deformation. Anyone know if this is the case?
