Short summary
High-resolution geochronology is one of the key factors to predict volcanic eruptions. To build up a high-resolution geochronological framework, we reported 21 new high-precision eruption ages (40Ar / 39Ar) for a ~ 3.3 × 106-year-old volcanic field: Milos (Greece). In combination with geochemical information and eruption volumes from the volcanoes of Milos, the long-lived volcanic history could provide important clues for the prediction of volcanic eruptions.

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.

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
40.5 million years ago, Earth's climate warmed, but it is unknown why. Enhanced volcanism has been suggested, but this has not yet been tied to a specific region. We explore an increase in volcanism in Iran. We dated igneous rocks and compiled ages from the literature. We estimated the volume of igneous rocks in Iran in order to calculate the amount of CO2 that could have been released due to enhanced volcanism. We conclude that an increase in volcanism in Iran is a plausible cause of warming.

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.
