Rb-Sr isotopic analyses of K-feldspar from Immel mine preclude the possibility that the Rb-Sr data reflect feldspar inclusions. Sphalerites from the main ore zone of Daniel’s Harbour mine, New- foundland, do not form a linear isochron and open behavior of the Rb-Sr system is suspected. Sphalerites Although K-Ar, Rb-Sr, Sm-Nd, and Pb-Pb methods ought to yield concordant isochron dates for each of these magmatic events, these four radioisotope pairs gave significantly discordant ages. Special allowance was made for larger-than-conventional uncertainties expressed as 2σ errors associated with the calculated “ages.” What does rb-sr mean?

Online chemical separation of Rb and Sr is possible in an O 2-filled 1965-10-01 Rb–Sr data for biotite, feldspar and whole rock from a regional metamorphosed pelitic schist give an isochronage of 1450±40 Ma,which is interpreted as a cooling age resulting from crustaluplift.
