地球重大事件年代探討

　


　

　

定年學研究工作的主要目的之一，在於了解地球系統內發生事件的年紀與相關演化速度。例如︰恐龍什麼時候絕滅？人類起源是發生在什麼時候？生物大爆炸又發生在什麼時候？等等。回答這些問題，當然可以依據很多種方法所獲得的資料，但最直接的方式，是利用定年法分析當時發生事件時所產生的地球物質，如礦物與岩石等。而在過去的地球歷史中，在亞洲地區所發現的重要地球事件有許多，例如︰第四紀的隕石撞擊事件、二疊－三疊紀時候的生物大絕滅事件、中生代 鳥類的起源、舊石器時代人類遺跡等等。由於本實驗室設備提供了優良的定年技術，因此，本實驗室的部份研究工作，即責無旁貸地與相關的學者合作研究進行上述地球事件的定年工作。
