Second, the impurity migrates into the subsurface region by a mechanism involving vacancies. This affects the surf

Jeff Speck we analyze the U–Pb zircon age database published for the Southern Central Andes. In the early Mesozoic (rift stage) the source regions were locally and strongly influenced by the active volcanism coeval with the extensional tectonic activity. The rift relief associated with the synrift stage laste
