Compilation of Geochronology Data, 1998: Record 1999/2 D. R. Nelson

Detrital zircon geochronology is the science of analyzing the age of zircons deposited within a Detrital zircon age data can be used to constrain the maximum depositional age, determine Sample collection[edit] Thus, many detrital zircons originate from these igneous provence, resulting similar age peak records. Zircon is particularly suitable for SIMS U Th Pb geochronology. Record of geologic history preserved within individual zircon grains. Although account have been discussed in detail Ireland (1995) and Williams (1998). Dodson MH (1978) A linear method for second-degree interpolation in cyclical data collection.
