Figure F10. Tera-Wasserburg plot of zircons from Cores 180-1108B-6R (square), 180-1110B-3X (circles), and 180-1111A-16R (triangles). Zircons from rhyolite clasts gave an age of 15.7 ± 0.4 Ma (MSWD = mean squared weighted deviates), and zircons from a microgranite clast gave 238U/206Pb ages of 3.1 and 550 Ma.
