Zircon (Zr,Hf)SiO4, a common mineral in felsic rocks, preserves invaluable information about the parental magmas due to its exceptional stability. Findings of cm-size zircon crystals in (ultra)mafic rocks are at odds with the experimentally derived high dissolution rates and saturation at low pressures (< 1 GPa) in low-silica melts. To explore the zircon stability in the mantle, we established the saturation and the kinetics of zircon dissolution in basaltic melt at 0.5-2 GPa and discovered zircon stabilization at 1–2 GPa. Our discovery of zircon stabilization with pressure and slower Zr diffusion as a network-former in major element contents (wt% ZrO2) compared to the network modifier in trace contents (ppm Zr) provides unique physical chemical conditions for zircon survival and the dissolution-recrystallization in the crust-mantle system.
