| Abstract | article A suite of 23 basaltic to dacitic lavas erupted over the last 350 kyr from the Mount Adams volcanic field has been analyzed for U-Th isotope compositions to evaluate the roles of mantle versus crustal components during magma genesis. All of the lavas have ( 230 Th/ 238 U) N1 and span a large range in ( 230 Th/ 232 Th) ratios, |
