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

Archaeometry, EarlyView.
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)

Archaeometric Characterization of Submerged Sasanian Stucco From Ghaleh Guri, Western Iran

Archaeometry, EarlyView.
ABSTRACT The Ghaleh Guri archaeological site, a late Sasanian site with a building complex dated to 591–628 ce, lies along an ancient road linking the western Zagros to Mesopotamia. Its architectural remains, adorned with stucco, faced annual river floods yet remained stable for centuries.

Earthquake Stress Drops, Ambient Tectonic Stresses and Stresses That Drive Plate Motions

pure and applied geophysics, 1977
A variety of geophysical observations suggests that the upper portion of the lithosphere, herein referred to as the elastic plate, has long-term material properties and frictional strength significantly greater than the lower lithosphere. If the average frictional stress along the non-ridge margin of the elastic plate is of the order of a kilobar, as ...
