Paleointensity determinations at elevated temperatures - Sample preparation techniqueA technique has been developed for the encapsulation of rock samples in order to prevent the chemical alterations which commonly accompany paleointensity measurements at elevated temperatures. The technique involves vacuum pumping at about 100 C of the sample as placed in a silica tube. The tube containing the sample and a Ti 'getter' are sealed under vacuum. Measurements can be made at 200 and 300 C. Immediately after this, the sample is sealed-off from the getter. The sample is now ready for measurements at higher temperatures.
