Diamonds mined from the Victor kimberlite (Ontario, Canada) grew at ~ 720 Ma in lherzolite-dominated substrates that themselves were generated ca. 400 My earlier by metasomatic overprinting of refractory harzburgites-dunites with proven Archean heritage.

Prolonged mantle residence of zircon xenocrysts from the western Eger rift
, 2009 Zircon is a common mineral in continental crustal rocks. As it is not easily altered in processes such as erosion or transport, this mineral is often used in the reconstruction of geological processes such as the formation and evolution of the continents.
