Andean surface uplift constrained by radiogenic isotopes of arc lavas [PDF]

Nature Communications, 2018
Multiple complex tectonic and climatic processes have formed the Andes, which today provides a unique ecological niche. Here, Scott et al. investigate how the chemical composition of lavas from stratovolcanoes can be used to give insight on the uplift of

Interactions between distal epiclastic and bio‐chemogenic sedimentation at the foothills of a mafic alkaline volcano: The case of the Oligocene Doupovské Hory Volcanic Complex (Czech Republic)

The Depositional Record, 2023
Late Oligocene (ca 25 Ma) volcano‐sedimentary successions exposed on the western periphery of the Doupovské Hory Volcanic Complex reveal a complex sedimentation history influenced in various ways by decay of the alkali basalt volcanic edifice. Weathering

Constraints on Martian Chronology from Meteorites

Geosciences, 2020
Martian meteorites provide the only direct constraints on the timing of Martian accretion, core formation, magmatic differentiation, and ongoing volcanism. While many radiogenic isotope chronometers have been applied to a wide variety of Martian samples,
