Garnet could be the ultimate petrochronometer. Not only can you date it directly (with an
accuracy and precision that may surprise some), but it is also a common rock-forming and …

Determination of accurate temperatures for geological events has been the grail of stable
isotope geochemistry since the seminal 1947 paper by Urey. In theory, this should be …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

Skarn deposits are one of the more abundant ore types in the earth's crust and form in rocks
of almost all ages. Skarn is a relatively simple rock type defined by a mineralogy usually …

Porphyry deposits arguably represent the most economically important class of nonferrous
metallic mineral resources. These magmatic-hydrothermal deposits are characterized by …

Metamorphic and magmatic garnets are known to fractionate REE, with generally HREE-
enriched patterns, and high Lu/Hf and Sm/Nd ratios, making them very useful as …

Andradite-rich garnet is a common U-bearing mineral in a variety of alkalic igneous rocks
and skarn deposits, but has been largely neglected as a U–Pb chronometer. In situ laser …

Garnets from skarns in the Beinn an Dubhaich granite aureole, Isle of Skye, Scotland, have
a large range of concentrations of uranium (0· 2–358 ppm) and the rare earth elements …

High precision and accuracy with in situ analysis has been a “holy grail” for generations of
stable isotope geochemists who employed a range of strategies for separation of …

A large instrumental mass fractionation (IMF) occurs during the measurement of oxygen
isotope ratios by secondary ion mass spectrometry and the magnitude of this fractionation …
