The effect of glass contained in rocks on the sound velocity is remarkable at high temperatures. Much less than 1% of glass included in the rock specimen can be easily detected by the present sound-velocity method, if the glass geometry is a film or tube of small aspect ratio.
The velocity-temperature relations (the V-T) for lehrzolite, as well as several igneous rock types, were studied up to 900-950°C at moderate constant pressure under quasi-dry conditions. Above 900°C, it was observed that the downward deflection of the V-T from a linear relation becomes remarkable for lehrzolite, but not for olivine xenoliths. This indicates that the partial melting of anhydrous lehrzolite commences at 900°C, corresponding to the temperature of the upper rim of the low velocity zone. This means that the existence of a quasi-dry low velocity zone is possible.
