Mantle Recycling: Transition Zone Metamorphism of …

Most have been recovered after crushing very large (up to 1100 kg) samples in commercial-scale plants, followed by magnetic and heavy-liquid separation (Xu et al., 2009, 2015). This makes it difficult to determine their context, and has led to some skepticism in the research community regarding their significance, or even their natural occurrence.
