Hello, I need to see what others think about this situation.
I have a material said to be basalt. I have been given major element data in ppm and would l like to use the percentages of corresponding oxides moving forward. Here is the deal:
Al2O3 is 16.31% in the ball park. Given Al at 43,152.08 ppm.
Fe2O3 is 10.15% in the ball park. Given Fe at 41,625.02 ppm.
SiO2 is 1.41%. Given Si at 4,498.08 ppm.
[(Element ppm)(Oxide mass/Element mass)/(10,000)] = % Oxide
Is this correct? Any ideas what this material might be?
