Loss of iron to gold capsules in rock-melting

1999-10-1  Gold is used widely for capsules in high-temperature rock-melting studies because it is generally thought to absorb negligible Fe from silicate samples. However, we observed significant losses of Fe from fluid-absent melting experiments on hornblende gabbros at 800-975 degrees C and 8 kbar, using standard piston-cylinder techniques.
