A mineral that forms under conditions as variable as diagenesis to deep subduction, melt
crystallization to low temperature alteration, and that retains information on time …

Global data for measured Fe 2 O 3/FeO ratios and Cu contents in unaltered volcanic and
intrusive arc rocks indicate that, on average, they are slightly more oxidized than other …

We derive a novel method for determining the oxidation state of a magma as zircon
crystallized, with a standard error of±0· 6 log unit ƒO2, using ratios of Ce, U, and Ti in zircon …

A comprehensive database of zircon composition in West Australian magmatic rocks reveals
negative correlations between both U and Th zircon/whole rock ratio and the zircon …

The chronologic record encoded in accessory minerals, based on the radioactive decay of U
and Th, is indispensable to extract quantitative process rates over timescales encompassing …

Abstract The Central Asian Orogenic Belt (CAOB) hosts a number of porphyry Cu deposits,
all associated with calc-alkaline granitic rocks and ranging in size from giant to small. Major …

The redox sensitivity of Ce and Eu anomalies in zircon has been clearly demonstrated by
experimental studies, and these may represent an important tool in the exploration for …

Using a newly-calibrated relation for cerium redox equilibria in silicate melts (Smythe and
Brenan, 2015), and an internally-consistent model for zircon-melt partitioning of Ce, we …

Abstract Porphyry Cu (±Mo±Au) and epithermal Au-Ag deposits are major sources of mined
metals and are commonly formed by magmatic-hydrothermal fluids derived from hydrous …

The determination of La and Ce anomalies in natural waters, biological samples and
biogenic sedimentary rocks can provide unique information on biogeochemical processes in …
