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 …

Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

The end-Cretaceous event was catastrophic for terrestrial communities worldwide, yet its
long-lasting effect on tropical forests remains largely unknown. We quantified plant …

The LA‐ICP‐MS U‐(Th‐) Pb geochronology international community has defined new
standards for the determination of U‐(Th‐) Pb ages. A new workflow defines the appropriate …

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 …

Flood basalts, the largest volcanic events in Earth history, are thought to drive global
environmental change because they can emit large volumes of CO2 and SO2 over short …

The Chicxulub asteroid impact (Mexico) and the eruption of the massive Deccan volcanic
province (India) are two proposed causes of the end-Cretaceous mass extinction, which …

40Ar/39Ar and K–Ar geochronology have long suffered from large systematic errors arising
from imprecise K and Ar isotopic data for standards and imprecisely determined decay …

A potential zircon reference material (BB zircon) for laser ablation‐inductively coupled
plasma‐mass spectrometry (LA‐ICP‐MS) U‐Pb geochronology and Hf isotope geochemistry …

Determining the absolute duration of magmatic-hydrothermal events leading to the formation
of porphyry systems (ie, including porphyry copper, skarn, and epithermal deposits) is one of …
