TL;DR: In this paper, the authors present a synthesis of 0-5 Ma paleomagnetic directional data collected from 17 different locations under the collaborative Time Averaged geomagnetic Field Initiative (TAFI) when combined with regional compilations from the northwest United States, the southwest United States and Japan, New Zealand, Hawaii, Mexico, South Pacific, and the Indian Ocean, a data set of over 2000 sites with high quality, stable polarity, and declination and inclination measurements.

TL;DR: In this article, the authors used step-heating to identify inherited Ar in the samples due to incomplete degassing of the Cretaceous volcanic rocks during impact melting, which is consistent with, but more precise than, previous K-Ar and fission track ages.

TL;DR: In this article, the authors reported 40Ar/39Ar ages from various tectonic units in the Aegean and westernmost Turkey, and they proposed that distinct stages of high pressure metamorphism were controlled by the underthrusting of fragments of mainly thinned continental crust and that these punctuated events were superposed on progressive slab retreat.

TL;DR: In this paper, the authors presented the first examples of 40Ar/39Ar age spectra for hornblende and biotite derived by the laser step-heating of individual grains.

TL;DR: In this article, high-resolution ion microprobe, K-Ar and Ar-Ar data from the southernmost Dom Feliciano Belt allow the identification of four major events.
