Quote from Atlantin:
"Subduction zones are concepts postulated by professors who are not versed in physics. They make no sense. Try to make whipped cream plunge into and below the ice cream in a sundae. It makes no sense given the difference in density of crustal elements and lower levels and the fragility of the crust not to mention the absence of an energy source to power such a plunge. A better term for it is Subduction Myth. Empirical evidence of such zones is also lacking."Sigh...Democrats and Liberals have done their jobs well. Not only do we have a nation of non-thinkers, but they now go so far as to deny the existence of empirical evidence. For those who still have a few functional synapses, I present the following empirical evidence (obtained by Geophysicists) of SUBDUCTION ZONES:
Subduction zone studies - An introduction to the subject with many links.
Delaunay representation of slabs
3D simultaneous seismic refraction and reflection tomography of wide-angle data from the central Chilean margin
Andean Continental Research Program to image an active subduction - My personal favorite, with good images of seismic reflections of a subduction zone
