The order-of-magnitude estimates in this paper indicate that shear heating during the dynamic fracturing and pulverization of rocks, for which the friction coefficient on the distributed cracks remains high (μ ∼0.6), can lead to a temperature rise of 100 °C under shallow crustal conditions. This is likely a conservative estimate.
