Abstract
:
Forty-three samples of volcanic rocks were selected from 5 widely spaced mineralized areas within the Hulayfah Group in the Arabian Shield. These samples were analysed for major and minor oxides as well as Nb, Zr, Y, Ti and P. The analyses were plotted on some of the commonly used petrochemical discrimination and variation diagrams in a trial to test the mobility of elements, but not to deduce tectonic setting or magma type. Nb and Y showed the highest mobility, Ti and Zr showed relatively moderate mobility with Ti being somewhat more mobile, but P showed the least mobility. It is suggested that the partial pressure of carbon dioxide, and whether it is buffered by an external source or not, have a considerable effect on the mobility of these elements during metamorphism and alteration.
