Cosmogenic nuclide dating
Abstract when the recurrence intervals of large earthquakes span several thousands of years, the dating of fault movements over long time intervals is essential for estimating the next event. The ldeo cosmogenic dating group, applies terrestrial cosmogenic nuclides as chronometers and tracers in the earth sciences terrestrial cosmogenic nuclides are produced by interactions between secondary cosmic rays and near surface rocks our research interests cover a wide spectrum of earth. With a holistic view of the environment the authors show in this book how cosmogenic radionuclides can be of cosmogenic (and other tracer and dating.
We do not do radiocarbon dating of organic materials such as bone the terrestrial cosmogenic nuclide facility is made up of four chemistry labs and a computer lab:. Why use cosmogenic nuclide exposure dating radiocarbon dating is abundantly used and offers very high precision dates, but we often want to date an event that is either too far in the past, or without the right type of organic matter, to be dated by 14c.
