Are you seriously making the claim that the North American Plate is stationary in the western region? Seriously?
Full-well being aware of the Snake River Plain?
Talk about a complete misunderstanding, the MT Data image was posted specifically to show there are other sources of evidence indicating a much wider field of magma, extending far into the heartland of Wyoming, than was previously understood. You, sir, picked the word "magma" apart, in an attempt to demonstrate your superior knowledge, when it was perfectly obvious of what I was speaking."Current studies suggest that the Snake River Plain resulted from the passage of the North American Plate over a stationary mantle plume or “hotspot” that is currently located beneath Yellowstone National Park" - from here
....And your continued use of this image is laughable:
The diagram is describing only what is occurring in the crust (lithosphere). It doesn't address any conditions deep in the Mantle, the way this diagram does:
....and the water indicated in the surface conditions of this diagram are describing the Pacific Ocean, unless you can show me a large body of water between Yellowstone and the Pacific ocean. The scale on that diagram is completely distorted.
It should be obvious, the Juan de Fuca/North American Subduction Zone is responsible for the hotspot that caused Yellowstone, and it should be obvious that hotspot has remained stationary while the North American plate has continuously moved westward over that stationary spot - just like are the conditions at all the other hotspots found around the world....
