Radiometric dating of surface rocks


No matter what the geologic situation, these basic principles reliably yield a reconstructed history of the sequence of events, both depositional, erosional, deformational, and others, for the geology of a region. Second, it is an approach doomed to failure at the outset. As the rigs drill down, the drill bits cut around a portion of the ice, capturing a long undisturbed "core" in the process. Finally, the inferred age of the shocked quartz, as determined from the age of the melted feldspar in the Manson impact structure So it's not clear to me how one can be sure of the 4. Also, it is reasonable to assume that as argon leaves the mantle in successive eruptions, the amount of argon remaining is reduced, so that later lava flows are less susceptible to such artificial increases in age. For this reason, there is some uncertainty as one goes back towards , years. Isotopic composition of argon in modern surface volcanic rocks. Finally, the fact that the great majority of dates are from one method means that the general but not universal agreement of K-Ar dating with itself is sufficient to explain the small percentange of anomalies if it is small. Unfortunately, Gerling's original calculations are incorrect primarily because Nier's ancient lead ore is not truly "primeval" in composition.
