The timescale for the generation of granitic magmas and their subsequent intrusion, crystallization, and cooling as plutons is no longer incompatible with the biblical time frames of the global, year-long Flood cataclysm and of 6,000–7,000 years for earth history. Though partial melting in the lower crust is the main rate-limiting step, it is now conjectured to only take years to decades, so partial melting to produce a large reservoir of granitic magmas could have occurred in the pre-Flood era as a consequence of accelerated nuclear decay early in the Creation Week. Rapid segregation, ascent, and emplacement now understood to only take days via dikes would have been aided by the tectonic "squeezing" and "pumping" during the catastrophic plate tectonics driving the global Genesis Flood cataclysm. Now that it has also been established that granitic plutons are mostly tabular sheets, crystallization and cooling would be even more easily facilitated by hydrothermal convective circulation with meteoric waters in the host rocks. The growth of large crystals from magmas within hours has now been experimentally determined, while the co-formation in the same biotite flakes of adjacent uranium and polonium radiohalos, the latter from short-lived parent polonium isotopes, requires that crystallization and cooling of the granitic plutons only took about 6–10 days. Thus the sum total of time, from partial melting in the lower crust to crystallization and cooling of granitic plutons emplaced in the upper crust, no longer conflicts with the biblical time frame for earth history, nor is it an impediment to accounting for most of the fossil-bearing geologic record during the global year-long Flood catastrophe.
