The mineral zircon is extremely variable both in terms of external morphology and internal
textures. These features reflect the geologic history of the mineral, especially the relevant …

The continental crust is the archive of the geological history of the Earth. Only 7% of the crust
is older than 2.5 Ga, and yet significantly more crust was generated before 2.5 Ga than …

Matrix-matched calibration by natural zircon standards and analysis of natural materials as a
reference are the principle methods for achieving accurate results in microbeam U–Pb …

Zircon has played a critically important role in our understanding of the growth and evolution
of the Earth. The U–Pb isotope system as preserved in zircon, more than any other mineral …

Zircon has long been recognized as the best geochronometer and the most important
timekeeper in geosciences. Modern microbeam techniques such as SIMS and LA‐ICPMS …

We report detailed high precision combined single grain U-Pb and Lu-Hf studies of early
zircons to obtain more reliable indications of the extent of mantle depletion and crustal …

The development of improved techniques for the in situ analysis of U–Pb, Lu–Hf and O
isotopes and of trace element contents has revolutionized approaches to modeling the …

Baddeleyite has long been recognized as one of the most important U-bearing minerals for
dating silica undersaturated igneous rocks. Age determination of baddeleyite calls for …

The Gangbian alkaline complex in the southeastern Yangtze Block (South China) is
composed of Si-undersaturated pyroxene syenites and Si-saturated to-oversaturated …

We integrate petrography and SIMS REE analyses of garnet and polyphase zircon from a
pelitic granulite adjacent to the Ronda peridotite, Betic Cordillera, southern Spain to …
