Interpreting the wealth of new data derived from the diverse suite of modern single-grain
provenance approaches available to a sedimentologist requires a thorough understanding …

Plate tectonic forcing leads to changes in the physical conditions that affect the lithosphere.
In response to such changes, notably the local temperature (T) and pressure (P), rocks …

The Th/U ratios of zircon crystals are routinely used to help understand their growth
mechanism. Despite the wide application of Th/U ratios in understanding the geological …

Subduction zones are unique to Earth and fundamental in its evolution, yet we still know little
about the causes and mechanisms of their initiation. Numerical models show that far-field …

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 …

Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) map** is a
rapidly expanding field in the geosciences because of the wealth of spatial information it …

Recent advances in laser ablation reaction-cell mass spectrometry have opened the
possibility for rapid and efficient Lu-Hf age dating of a variety of minerals. Of particular …

The astonishing progress of personal computer technology in the past 30 years as well as
the availability of thermodynamic data and modeling programs have revolutionized our …

The temperature sensitivity of the U-Pb apatite system (350–570° C) makes it a powerful tool
to study thermal histories in the deeper crust. Recent studies have exploited diffusive Pb loss …

Partial melting is the fundamental process by which juvenile crust was produced from the
mantle and subsequently reworked to become the stable, compositionally-differentiated …
