Using the Igneous classification chart according to Silica content, would it be correct if a rock has 50% Silica then the components would be about 8% Olivine, 77% Pyroxene, and about 15% Calcium Plagioclase? Likewise if a rock has 45% Silica then then it would have 55% Olivine and 45% Pyroxene? Please let me know if I am interpreting the chart correctly? Many thanks
