Loss of iron to gold capsules in rock-melting experiments
Loss iron gold capsules rock-melting experiments
font style='font-size:12px;'>
2012/4/1
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
