Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract Detachment faults in mid‐ocean ridge settings accommodate tectonic extension. These faults are potentially weakened by alteration through phyllosilicate‐ and amphibole‐mineral formation. Seven core samples taken from the Krafla and Reykjanes geothermal fields in Iceland allow for the study of the effect of mineral alteration on the frictional ...
