Abstract

Columnar joints in lavas form during cooling, but the temperature this occurs at is unclear. Here, the authors perform thermo-mechanical experiments on basaltic rocks to examine the temperature of columnar joints in lavas and find that failure occurs at 890–840 °C, which is below the solidus temperature of 980 °C.
