Search for impact ejecta at the Paleocene–Eocene boundary
Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1585-1592, July 2026.Abstract Almost 10 years have passed since microtektites and microkrystites were reported for the Paleocene–Eocene (P–E) boundary in drill cores and outcrop in New Jersey and in ODP Hole 1051B in the western North Atlantic. The glassy spherules were interpreted to reflect an impact trigger for the Paleocene–Eocene Thermal Maximum (PETM).

Loess Studies in Aotearoa New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.
