These types of minerals often produce lower precision ages than igneous and metamorphic minerals traditionally used for age dating, but are more common in the geologic record. Internet URLs are the best. Any text you add should be original, not copied from other sources. Our editors will review what you've submitted, and if it meets our criteria, we'll add it to the article. In areas with a high concentration of the parent isotope, damage to the crystal lattice is quite extensive, and will often interconnect to form a network of radiation damaged areas. Please note that our editors may make some formatting changes or correct spelling or grammatical errors, and may also contact you if any clarifications are needed. Previous article in issue. This is termed the lead—lead dating method. This review will be limited to some aspects of the U—U—Th—Ra system with half-lives of kyr, 76 kyr and 1. Half-lives of radioactive isotopes of such elements range from seconds to many millennia and application depends on the natural timeframe of the process or the elapsed time. However, pure authigenic precipitates are rare and many contain some allogenic material, mostly silicate with U in secular equilibrium with significant Th.

    Interaction between mineralogy and radioactive breakdown[ edit ] During the alpha decay steps, the zircon crystal experiences radiation damage, associated with each alpha decay.

    This damage is most concentrated around the parent isotope U and Th , expelling the daughter isotope Pb from its original position in the zircon lattice.

    The U-series decay chains contain many elements that can be fractionated in environmental and geological processes.

    These fission tracks inevitably act as conduits deep within the crystal, thereby providing a method of transport to facilitate the leaching of lead isotopes from the zircon crystal. You may find it helpful to search within the site to see how similar or related subjects are covered.

    However, use of a single decay scheme usually U to Pb leads to the U—Pb isochron dating method, analogous to the rubidium—strontium dating method. Clair Cameron Patterson , an American geochemist who pioneered studies of uranium—lead radiometric dating methods, is famous for having used it to obtain one of the earliest estimates of the age of the Earth.
