Chamberlain, K.J.; Wilson, C.J.N.; Wooden, Joseph L.; Charlier, B L A; Ireland, Trevor

Description

We present zircon textural, trace element and U-Pb age data obtained by secondaryion mass spectrometry (SIMS) (SHRIMPRG: sensitive high-resolution ion microprobe, reverse geometry) from 15 stratigraphically controlled Bishop Tuff samples and two Glass Mountain (GM) lava samples (domes OD and YA). Bishop zircon textures divide into four suites: (a) dominant sector-zoned grains, with (b) subordinate grains showing bright rims [lower U, Th, rare earth elements (REE)] in CL imaging, (c) sparse...[Show more]
