  • 綠島大部份由安山岩質熔岩及集塊岩所組成,偶而夾有凝灰岩及碎屑岩流。本研究之樣本為採自綠島西北方靠近燈塔的露頭。樣本外觀為深灰色,多孔狀,具斑狀組織。礦物組成主要為斜長石、斜輝石;次要為鈦鐵氧化物,基質中多數為斜長石、斜輝石及少數不透明礦物。Na2O+K2O對SiO2作圖之分類,屬於玄武岩質安山岩。

    從高溫實驗結果得知,綠島安山岩質岩漿在常壓下之液相溫度為1289℃,固相溫度略低於1099℃,整個熔融區間為190℃。實驗結晶順序與溫度如下:在1289℃,鉻鐵尖晶石率先晶出;至1264℃,斜長石晶出;到1189℃,鉻鐵尖晶石消失,轉變成氧化物出現;持續降溫至1184℃,直輝石晶出;爾後降溫至1162℃,斜輝石為最後一種礦物相晶出。

    整體而言,常壓下綠島安山岩之殘餘熔體成分隨實驗溫度降低,SiO2、K2O含量有上升趨勢,而Al2O3、ΣFeO、MgO、CaO則呈減少變化。Na2O則先升後降。另外從成分變化圖,可得知:ΣFeO、MgO、CaO與SiO2呈一明顯負變關係,暗示著綠島之岩漿活動主要受制於鐵鎂礦物的結晶分化。以及,隨結晶分化進行之殘餘熔體成分變化,與綠島的天然岩石成分類似,故推測綠島的天然岩石可在低壓下結晶分化而成。而AFM圖中,殘餘熔體成分隨實驗溫度降低,最後亦朝Na2O、K2O富集。
