"...Mostly they say the dating methods are inconsistent with each other. The U-Th-Pb and fission track data show a wide range of ages for Middle Cambrian rock strata and are thus highly discordant. ...This discordance means that the U-Th-Pb and fission track dating methods give wildly different dates for the zircon samples measured, most of which strongly diverge from the secular age expected for the Middle Cambrian rock. Similarly, the fission track dating for the Late Jurassic samples gives results that diverge from the expected geologic age. ..results seem to suggest an ebb and flow of volcanic activity from the Middle Cambrian through the Late Jurassic systems that carried zircon crystals experiencing varied amounts of accelerated nuclear decay to crustal rock during the early and mid-stages of the Flood. A model based on the Genesis Flood better explains these volcanic units if they occurred rapidly one after another during a short time frame while experiencing varying accelerated decay rates and significant mixing of the rock crystals contained therein."
