Timescales of Magma Recharge and Reactivation of Large Silicic Systems from Ti Diffusion in Quartz

Abstract:

Timescales of magma chamber assembly and recharge are investigated here by applying 1D and 2D diffusion modeling techniques to high-resolution maps of titanium in quartz from a large-volume ignimbrite eruption in the Taupo Volcanic Zone, New Zealand. We compare quartz zonation patterns and associated diffusion timescales from the ∼340 ka Whakamaru super-eruption (magma volume ∼1000 km. 3) with the Younger Toba Tuff super-eruption, 74 ka (2000 km. 3), Sumatra, and the smaller volume ∼50 ka Ear...
