A Microkrystite from the Australasian Tektite/Microtektite Strewn Field

Meteoritics &Planetary Science, EarlyView.
Abstract Microkrystites are glassy impact spherules. They contain primary crystallites carrying information on the physical and chemical conditions prevailing during vaporization, melting, and ejection in large impact cratering events. We report on the geochemistry and mineralogy down to nanometer scale of the first microkrystite (ODP1144A,14) from the

Reconstructing Cenozoic grasslands in North America and western Eurasia: evidence for cold‐season grasses from 3D phytolith morphology

New Phytologist, EarlyView.
Pie charts illustrate the composition of fossil grass silica short‐cell phytolith (GSSCP) assemblages at investigated fossil sites in the United States and Türkiye and representative 3D meshes of classified phytoliths. Summary Pooideae, the largest grass subfamily, radiated in the Northern Hemisphere from the Paleocene onward and today dominates cold ...

Tectonic Forcing of Diachronous Salt Deposition During the Badenian Salinity Crisis Revealed by U–Pb Dating of Tephra Overlying Tuzla Basin Evaporites

Terra Nova, EarlyView.
ABSTRACT During the Middle Miocene Badenian Salinity Crisis (BSC), extensive evaporites formed across different tectonic settings in the Central Paratethys. Limited age constraints hamper evaporite correlation and identification of driving mechanisms. Here, we use U–Pb dating of zircon by LA‐ICP‐MS from tephra overlying the Tuzla Basin evaporites.
