In this paper we present a Rb-Sr dating reconnaissance of the granulites, amphibolites samples from a metamorphic terrain rnight define a whole-rock Rb-Sr.

Total procedure blanks for Rb and Sr were 20 pg and 50 pg, respectively, less than 1% of most of the samples. Blank corrections were made for data in Table la, using a 87Sr/s%r of ratio of 0.709. A VG sector multi-collector The application to Rb/Sr dating is evaluated and shown to result in expected age overestimates when isotopic ratios are employed to linearize the isochron.

For example, Woodmorappe claims that age data is routinely "explained away" (p. 102) or "rationalized away" (p. 113), that some age values are "arbitrarily" accepted or rejected as true (p. 113), that anomalous dates are not reported in the scientific literature (p. 114), that some geologists have "fudged" Rb-Sr isochrons (p. 118 & 120), and that geologists "cover-up the basic failure of the

The rubidium-strontium dating method is often used in geologic studies. Clocks in the Rocks. Older example of Rb/Sr. Index 7 Oct 2020 a new in situ Rubidium-Strontium (Rb-Sr) age-dating technique, minutes rather than weeks, and with the sample's geological context intact.

Many samples have been analyzed by absolute dating techniques (K/Ar, Ar/Ar, Rb/Sr, U/Pb) and every sample has fallen between 63.5 to 66.4 million years ago. It is possible to conclude with scientific certainty that the Cretaceous Period ended about 65 million years ago.

Rb-Sr dating relies on correctly measuring the Rb-Sr ratio of a mineral or whole rock sample, plus deriving an accurate 87Sr/86Sr ratio for the mineral or whole rock sample. Several preconditions must be satisfied before a Rb-Sr date can be considered as representing the time of emplacement or formation of a rock. The system must have remained closed to Rb and Sr diffusion from the time at which the rock formed or fell below the closure temperature i.e the temperature at which a system has
