The rapid separation and determination of barium, strontium, and calcium in rocks and minerals

Published online by Cambridge University Press:  14 March 2018

Extract

Calcium is one of the most widespread and abundant of metals, coming fifth on the list of elements and third among the oxides of the outer lithosphere; it is an essential constituent of a great many rock-forming minerals and is, therefore, almost always present in rocks. Barium and strontium come very much lower in the list of abundance of elements, but nevertheless barium is extremely widespread and occurs in most rocks, igneous, metamorphic, and sedimentary, while strontium is also very widespread. It has been stated that the average content in igneous rocks of both of these elements is of the order of 0·05%.
