hypothesized that the rapid movement of the Indian continent occurred due to
subduction at both ends of the Tethys Sea and also at the
juncture of the oceanic basaltic section of the Indian continent and its fells
mass. This would amount to triple subduction, with the Tethys components
naturally ending at exactly the same moment, leaving only the one other
subduction continuing, until all of the oceanic basaltic section of the Indian
continent was subducted (or elevated in the collision with Eurasia).
Now a new article uses double subduction at the Tethys Sea to explain
the rapid movement of India. It appears that the idea of telescoping subduction
is now ready for prime time.
