Effect of temperature variation on internal friction in rocks.
J Geophys Res 1972 Mar; 77(8):1420-1423
The effect of temperature changes ranging from -200 deg to +600 deg c on the internal friction of rocks was measured by forster's method. Most, but not all, rocks showed what appeared to be a prominent loss peak near room temperature. This peak was associated with the presence of tiny quantities of moisture in the rock. If the rock was heated sufficiently and allowed to cool, the peak was reduced or eliminated.
