What can lithics tell us about hominin technology's ‘primordial soup’? An origin of stone knapping via the emulation of Mother Nature

Archaeometry, Volume 68, Issue S3, Page S8-S30, June 2026.
Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)

Subducting Slab Thermo‐Petrologic Structure and Intermediate‐Depth Supra‐Slab Earthquakes Beneath Southern Colombia

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We develop 2‐D thermo‐petrologic models for two transects through southern Colombia and compare the model‐predicted temperature distributions and depths of slab dehydration with seismological observations. Along the northern transect, earthquakes occur above the relatively young subducting Nazca slab at 80–160‐km depths.

Mineralogical Evidence for Highly Evolved Th‐Saturated Magma on Mars

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Thorium‐rich (Th‐rich) geological units have been detected by remote sensing in the Martian crust. However, there is still a lack of mineralogical evidence to constrain the magmatic processes responsible for these anomalies. In this study, we report the first discovery of thorite (ThSiO4) grains within a zircon fragment from Martian regolith ...

Barium Isotopes Indicate Spatiotemporal Heterogeneity of Marine Primary Productivity During the Toarcian Oceanic Anoxic Event

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Toarcian Oceanic Anoxic Event (T‐OAE, ∼183 Ma) was characterized by globally enhanced organic‐carbon burial and a negative carbon‐isotope excursion (N‐CIE). However, the role of marine productivity at this time, and its spatiotemporal variability, is unclear.
