| Abstract: | For estimating relative content of primary rock-forming minerals such as alkeli-feldspare, plagioclase, quartz, amphibole and biotite in volcanic rocks, the K-value method by means of X-ray poly-phase quantitative analysis is selected.
K-values of the above-mentioned five minerals are deferminated repeatedly using Cu, Co and Fe targent respectively, and the stable average values are obtained, then the standard samples are detferminated using K-value method quantitative analysis. The results show that the relative errors are generally less than 10%, thereby, the results of quantitative analysis are reliable and may be used to divide magma series of volcanic rocks. |
