Dating techniques uranium series

Uranium-series dating is by far the most widely-used dating technique applied to speleothems, and is only applicable to material that is currently in a state of disequilibrium. Given the rates of ingrowth of daughter isotopes of Pa and °Th, conditions of uranium-series disequilibrium in systems which have remained isotopically-closed are generally restricted to materials < 500 ka... [Pg.410]

Uranium Series Dating. Reliable dating of bone is possible when using the technique known as uranium series dating (see Textbox 16). The technique, which is also based on measuring relative amounts of uranium, makes possible dating very old bones, beyond the range that can be dated with radiocarbon, that is, over 40,000 years and up to 500,000 years old (Schwarcz 1997 Ivanovich and Harmon 1992). [Pg.413]

Unlike some dating techniques (such as uranium-series dating on speleothems or corals), radiocarbon is not an absolute dating technique, but relies on the comparison of radiocarbon measurements on samples to those made on samples of known age (a process called calibration). In order to understand the limitations and... [Pg.2022]

A few techniques exist that do not provide for direct dating but rather give information as to whether the object is of modem manufacture. One of these is dating (53). In the decay series of uranium, the first long-Hved member after Ra, with its 1622 yr half-life, is which has a 22 yr... [Pg.419]
