Investigation of iron isotope variability in the bimodal Aztec Wash Pluton, Eldorado Mountains, Nevada
… compositional zonation similar to that found in zoned plutons. The process that alters andesitic starting material to granitic and mafic end members within a temperature gradient is called thermal migration zone refining (Lundstrom, 2009). In addition to the compositional changes that occur …

The isotope geochemistry of uranium: Igneous petrology, ore deposits, and groundwater contamination
… the previous work on the isotopic effects of thermal diffusion into the heavy elements, and presents new research on the mineralogical development of a basalt under a thermal gradient. There are five studies in this work: 238U/235U is first applied to detect the effect of a thermal gradient on …
