Strontium isotope composition of rotorua geothermal waters

Geothermics, 1992
Strontium isotope compositions of Rotorua geothermal waters, taken in conjunction with chemical and stable isotope data, are broadly consistent with existing hydrogeologic models, and provide new insights into complex water-rock interactions and fluid-fluid mixing processes. Primary alkali chloride waters upwelling in the eastern part of the field have

Isotopic Homogenization of Strontium in Open Systems

1972
After the presentation and discussion of the isotopic composition of strontium in different igneous and sedimentary rocks in the preceding chapters, we now return to the problem of dating by the Rb-Sr method. We stated in Chapter II that one of the prerequisites for dating rocks or minerals is that their concentrations of rubidium and strontium and ...

Isotopic composition of strontium in Indian kimberlites

Geochimica et Cosmochimica Acta, 1979
Strontium isotopic studies on twenty three whole rock kimberlites from two petrographic provinces in India show variation of initial 87Sr86Sr ratios from 0.7027 to 0.7102. The variation is unrelated to the degree of alteration. Between the micaceous and basaltic varieties there is some overlap in the Sr isotopic ratios.
