Abstract:
|
A compelling new model for caldera evolution challenges the standard depiction of large-scale volcanism. Here, I test these competing models by establishing the temporal and chemical relationship between ignimbrite and potential cogenetic plutons related to the Questa caldera, Latir volcanic field, New Mexico.
