The deep interior of the North American craton is known only from so-called xenoliths - rock inclusions in igneous rock - or xenocrysts such as diamonds that have been delivered to the surface from deep below by volcanoes.
(U-Th)/He analyses suggest that the zircons as well as their host basalts erupted between 29 and 24 million years ago, but fragments from the same xenocrysts reveal U-Pb ages between 51 and 83 million years.
These sources include the active magma of the eruption in question phenocrysts), crystals from previous magmatism at the volcano (antecrysts) and wholly unrelated crystals (xenocrysts
