This paper describes migmatites and associated rocks in SW Finland that have been studied using the new in situ garnet and apatite Lu–Hf geochronology method. The metamorphic constraints and age presented in this paper enhance our understanding of the geological evolution in SW Finland. The results reveal detailed temporal constraints for the tectonic evolution that can be linked to major events in adjacent tectonic blocks in both Finland and Sweden during the Svecofennian orogeny.

Gravity aspects are applied to the well-known impact craters Popigai and Chicxulub. Findings about them from 2010 are confirmed and extended with better data and a more advanced method. Both craters are double or multiple craters. Both crater formations seem to be associated with impact-induced tectonics that triggered the development of impact grabens.

Sardinia and Corsica separated and have been drifting in the Mediterranean Sea for 35 Myr due to the retreat of the Ionian plate beneath the Tyrrhenian Sea. Using in-house and public data, we measured and interpreted receiver functions based on prior geophysical and petrological studies. Our findings indicate that the islands' ancient continental structure remains mostly unchanged. Alpine orogenesis about 50 million years ago influenced Corsica's crust, enriching it with water-bearing minerals.

The Tethyan orogenic belt records an extensive history of subduction along the southern margin of Eurasia. We examine the magmatism, stratigraphy, and sedimentary provenance of the Jurassic basin in the West Kunlun Mountains, highlighting the switching extensional and contractional tectonic episodes in central Asia. The complex evolution was related to the subduction of the Neo-Tethys Ocean, transitioning from southward retreat to northward flat-slab advancement.

Debate has long surrounded the tectonic affinity and evolution of Longshoushan during the Paleozoic. This study presents new zircon U–Pb ages, whole-rock major and trace element data, and Hf isotopic analyses for granitoids. (1) Longshoushan was influenced by the North Qilian Orogenic Belt in the early Paleozoic, (2) it transitioned from a post-collisional compressional to an extensional setting ~435 Ma, and (3) a three-stage early Paleozoic tectonic model is proposed.

Unlike episodic plate boundary earthquakes, their randomness makes predicting intraplate earthquakes challenging. This study aids in understanding intraplate earthquake behavior by analyzing paleo-earthquake records of the Yangsan Fault in Korea. Five trench sites revealed six Quaternary earthquakes, the latest 3000 years ago, with M_w 6.7–7.1. The right-lateral fault has a 0.13 mm yr^-1 slip rate and a recurrence interval of over 13000 years; it has been continuously active since the Quaternary.
