Ultrahigh‐temperature quartz‐sapphirine granulite xenoliths in the post‐Karoo Lace kimberlite, South Africa, comprise mainly quartz, sapphirine, garnet and sillimanite, with rarer orthopyroxene, antiperthite, corundum and zinc‐bearing spinel; constant accessories are rutile, graphite and sulphides....
