Question: Using the geochemical data below, determine graphically if Rock 2 can be derived from Rock 1 by fractional crystallization of olivine. Suggestion: plot all oxides

Using the geochemical data below, determine graphically if Rock 2 can be derived from Rock 1 by fractional crystallization of olivine.

Suggestion: plot all oxides vs SiO₂ on the same plot, but divide all MgO values by 10 before plotting so everything fits on a y-axis scale from 0 to 16 wt.%

Using the geochemical data below, determine graphically if Rock 2 can

please explain how to do in excel and please only answer if you actually know the answer. This is repost because my last attempt was responded to with some unrelated nonsense. Thank you!
