Short summary
Short summary
PlanetBuilder is an open-source Python program for modelling element distribution between the metallic core and silicate mantles of the Earth and other rocky bodies during growth. It can be used to calculate major and trace element abundances in the planetary core and mantle with user-defined complex accretion histories. By comparing results with sample-based observations, the initial evolution of planets can be constrained. The model can be used by geo-, planetary- and exoplanetary scientists.

Short summary
The island of Patmos is situated in the southern Aegean Sea (Greece), just north of the present locus of active volcanism. The island is almost entirely built up of volcanic rocks that are 6.6 to 5.2 million years old. We obtain these ages with 40Ar / 39Ar dating technique on sanidine and biotite minerals. Our new age data indicate a geologically brief volcanic period (lasting less than 1.5 million years) that can be divided into three volcanic intervals and correlated to tectonics.

Short summary
The TephATA database comprises morphological, geochemical, and chronological data of volcanic ash layers from the Atacama Desert. The dataset provides a basis for identifying the same volcanic ash layers in different sediment deposits and to determine their stratigraphic and chronological relationships. Known ages of volcanic eruptions can be transferred among equivalent ash layers, which allows dating of sediments. Also ash dispersal and the volcanic history of a region can be studied.

This study explores quartz veins in Germany's Rursee area, formed during the Variscan Orogeny and later reactivated by tectonic activity in the Jurassic–Cretaceous period. Using advanced isotopic dating techniques, it examines how these veins influenced fluid flow and quartz recrystallization. By tackling the challenges of dating fluid activity, this research offers new insights into argon gas degassing in quartz minerals.

Short summary
The Christiana Islands represents the oldest subaerial volcanism in the Christiana-Santorini-Kolombo volcanic field, but the exact age of this volcano has been unknown. This study reports new 40Ar/39Ar ages of ten volcanic samples from Christiana Island that cluster between 2.5–2.7 Ma with small uncertainties (0.02–0.14 Ma). One sample dated much younger: 133 ka; this is most likely derived from the Middle Pumice Plinian eruption of Santorini.
The Christiana Islands represents the oldest subaerial volcanism in the...
