U-pb dating of zircon by la-icp-ms

Z dating site. Events are rated in terms of the likelihood of involvement of a mantle plume head. Elío J., Crowley Q., Scanlon R., Hodgson J., Zgaga L. For some events, the volume of magma has also been estimated. The areal contribution from dikes is based on the length multiplied by the width of the swarm.

References: Selected references are cited as bracketed numbers. The calcium-potassium age method is seldom used, however, because of the great abundance of nonradiogenic calcium in minerals or rocks, which masks the presence of radiogenic calcium.

Significant advances have been made to the geology of many regions since this database was published. Estimates of the areal distribution of each event have large uncertainties and are generally minimum estimates.

. On the other hand, the abundance of argon in the Earth is relatively small because of its escape to the atmosphere during processes associated with volcanism.The potassium-argon dating method has been used to measure a wide variety of ages. Dating methods are coded as follows: A = Ar-Ar, K = K-Ar, R = Rb-Sr, S = Sm-Nd, U = U-Pb, P = Pb-Pb, M = paleomagnetism, G = geological correlations, b = baddeleyite, p = plagioclase, r= rutile, t = titanite, and z = zircon. Events are rated as A, B and C, where A= confidently linked, B= probably linked, and C= possibly linked – to a mantle plume head. We are currently working on revisions that will incorporate these advances.
