澎湖群島玄武岩可分為矽質玄武岩與鹼性玄武岩二類,其中在鹼性玄武岩中常發現超基性擄獲岩。本實驗之橄欖岩採自澎湖本島東北角的北寮地區,希望藉由超基性捕獲岩於不同溫壓環境下之實驗,由電子微探儀分析所生成之岩漿,期能對澎湖玄武岩之成因有所了解。
在各壓力下,隨著溫度上升,實驗生成之岩漿Al2O3、CaO、Na2O、K2O含量呈現減少之趨勢,而MgO含量呈現增加之趨勢
固相線附近實驗生成之熔融物質CaO含量、FeO/MgO及Mg#較澎湖玄武岩為高,顯示澎湖矽質玄武岩於生成之過程中,應經歷結晶分化之過程。
澎湖北寮橄欖岩之實驗結果:0.5GPa下生成石英矽質玄武岩,1GPa下生成橄欖石矽質玄武岩,1.5 GPa下生成更富含橄欖石端元之橄欖石矽質玄武岩。
