The geological society of america provides access to elements that are essential to the professional growth of business, and industry th230-u234 dating of. Dating of two deep-sea cores from the caribbean, about 600 km apart, has given a set of dates which are internally consistent identical, within the limits of error, in stratigraphically equivalent levels of the two cores and coincident with the c14 chronology this set of dates is believed to provide a reliable, absolute time scale.

U-series dating attempts to date cave paintings illustrate the difficulties of radiometric dating, and also show evidence of a young earth a recent article about u-series dating of paleolithic art in 11 caves in spain 1 contained some frank discussions about the wild assumptions that had to be made to date the paintings, and raised some interesting. Uranium-thorium dating is based on the detection by mass spectrometry of both the parent (234 u) and daughter (230 th) products of decay, through the emission of an alpha particlethe decay of uranium 234 to thorium 230 is part of the much longer decay series begining in 238 u and ending in 206 pb for uranium-thorium dating, the initial ratio of 230 th/ 234.

Since i have a longer term interest in the dating of the dasuopu ice core, i want to ensure that i’m fully cognizant of the details of speleo dating methods and have therefore tried to replicate reported results using my own nonlinear solver and, at the same time, get a better appreciation of whether the sorts of potential errors in this method could be.
