Dear Hirayama-san, thank you for your interesting pdf-presentation. I am wondering if you have tried to plot Sr-isotopes versus 1/Sr? Mixing should be a straight line on this diagram. Also, I am wondering what amount of assimilation of the granitic basement is required to make the rhyolites from the dacites? Do you consider bulk mixing through assimilation of crystal cargo, or partial melting of the basement, and if partial melting, where does the heat come from? Is the dacite hot enough to partially melt the granite? Thank you! Georg
