One should not make much of the very small observed range of isotopic fractionation in zinc because only a few samples were analyzed. Allegre, C. Edwards, B. This form of isotopic fractionation is ...

Small clouds of strontium atoms (blue) and rubidium atoms (red) are trapped together. The well-known properties of rubidium can be used to calibrate the applied magnetic field very precisely, which in ...

An oversight in a radioisotope dating technique used to date everything from meteorites to geologic samples means that scientists have likely overestimated the age of many samples, according to new ...

ISOTOPIC ages by potassium – argon and rubidium – strontium methods have been measured on some Spitsbergen rocks, in the hope of contributing to the Mid-Palægeozoic time-scale and to the understanding ...

IN a previous communication 1 I described an attempt to estimate the initial concentrations and partition coefficients of rubidium and strontium. The calculation was performed based on two possible ...
