[APD] Chemical Composition of Igneous Rocks
I typed the analysis of Basalts and Granites today at work. I hope they
don't loose their format as I paste them into this email. I am going to soak
the basalt in some DI water for a week and measure the pH of the solution
to see if there is any change. There is a granitic Rock quarry in
Riverdale, NJ. I hope to get some screenings from them. I will check the pH
as well.
