We review the ages of Quaternary magnetic polarity reversals and magnetic excursions. Improvements in radioisotopic 40 Ar/39 Ar dating of reversals and excursions reflect the use …
New ages for flowstone, sediments and fossil bones from the Dinaledi Chamber are presented. We combined optically stimulated luminescence dating of sediments with U-Th …

The time scale for marine magnetic anomalies for the Late Cretaceous through Neogene (C- sequence) and Middle Jurassic through Early Cretaceous (M-sequence with deep-tow …
INTRODUCTION Drimolen is one of several ancient caves located in the Hominid Caves of South Africa United Nations Educational, Scientific, and Cultural Organization (UNESCO) …
Marked by a progressive increase in the amplitude of climate oscillations, an evolving waveform, and a shift towards a quasi-100 ky frequency, the Early–Middle Pleistocene …
Abstract The Last Glacial Maximum (LGM) is widely used to refer to the episode when global ice volume last reached its maximum and associated sea levels were at their lowest …
Abstract The accuracy of 40 Ar/39 Ar geochronology relies in large part on precise and accurate calibration of the ages and K-Ar isotopic compositions of standards. A widely used …
The rewards from resolving the tempo of magmatic, paleobiologic, paleoclimatic, and tectonic processes at better than the per mil level of precision have spurred a quest within …
Paleomagnetic records from sediments, archeological artifacts, and lava flows provide the foundation for studying geomagnetic field changes over 0–100 ka. Late Quaternary time …
