The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Zircon ages in granulite facies rocks: decoupling from geochemistry above 850 °C? [PDF]
Contributions to Mineralogy and Petrology, 2018 Granulite facies rocks frequently show a large spread in their zircon ages, the interpretation of which raises questions: Has the isotopic system been disturbed? By what process(es) and conditions did the alteration occur?

Paleomagnetism indicates that primary magnetite in zircon records a strong Hadean geodynamo [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance The age and early history of Earth’s geomagnetic field can provide insight into the evolution of the core and atmosphere. But measurement of Hadean zircons—the oldest known terrestrial materials—and the determination of the antiquity of ...

A Novel Approach to Identifying Mantle‐Equilibrated Zircon by Using Trace Element Chemistry
Geochemistry, Geophysics, Geosystems, 2020 One of the requirements for inferring mantle redox states via zircon Ce/Ce* oxybarometry and Ti‐in‐zircon thermometry is to select mantle‐equilibrated zircon derived from melts that have not interacted with the hydrosphere nor assimilated exogenous ...

Constraining the long-term evolution of the slip rate for a major extensional fault system in the central Aegean, Greece, using thermochronology [PDF]
, 2006 The brittle/ductile transition is a major rheologic boundary in the crust yet little is known about how or if rates of tectonic processes are influenced by this boundary.

Does Zircon Shape Retain Petrogenetic Information?
Geochemistry, Geophysics, Geosystems, 2023 Zircon shape is commonly reported during geochronology and geochemistry analyses of igneous, metamorphic, and sedimentary rocks, but the relationship of zircon shape to primary growth environmental conditions remains poorly constrained.
