關西-竹東地區位於臺灣北部,地質上處於西部麓山帶,屬於臺灣西部火成岩區。該區玄武岩以凸透鏡體夾於新第三紀沈積岩層,大多為帶狀,出露於中新世晚期的地層中,產狀以火山碎屑岩為主,熔岩流比較少,此外岩床、岩脈亦在此區出現。本實驗樣本採樣地點為關西鎮六畜窩錦山溪旁之露頭,樣本岩石經計算其應存礦物成分,依據玄武岩四面體分類屬於鹼性玄武岩類。
本實驗利用高溫爐及高溫高壓儀進行一大氣壓與1.0京帕壓力下實驗岩石學研究,一大氣壓實驗步驟先將岩石磨成粉末,置於白金囊包中,設定溫度後,將樣本放入高溫爐內,經過數小時不等之反應時間,然後加以驟冷。1.0京帕實驗步驟則為將岩石粉末置於金鈀管囊中,再放入電爐組合,加壓至1.0京帕後,通電加熱,經數小時不等之反應,完成實驗。將實驗後之樣本灌膠,磨成光片,用反射式顯微鏡做初步鑑定,再用電子微探針分析結晶礦物與玻璃成分。
實驗結果為此玄武岩在一大氣壓下之全融溫度約在1316℃,固相溫度低於1050℃,結晶順序為鈦鐵氧化物(1316℃)、橄欖石(1258℃)、斜輝石(1166℃)與斜長石(1092℃)。1.0京帕下之結晶順序為石榴子石(1350℃)、鈦鐵氧化物(1330℃)、橄欖石(1280℃)、斜輝石(1220℃)與斜長石(1110℃)。一大氣壓下玻璃成分中SiO2與CaO含量隨溫度降低而增加,MgO、FeO、Na2O與K2O含量隨溫度降低而減少。1.0京帕下玻璃成分中SiO2與K2O隨溫度降低而增加,MgO與CaO含量隨溫度降低而降低。由一大氣壓與1.0京帕之各溫度下玻璃成分的玄武岩四面體應存礦物成分圖,與前人所做的全岩分析成分比較,此區橄欖石矽質玄武岩與石英矽質玄武岩可在較低壓的環境(約1.0京帕至一大氣壓之間)經結晶分異而形成。
