    ● Pangaea

    Pangaea or Pangea (παν, pan, meaning entire, and γαια, gaia, meaning Earth in Ancient Greek) was the supercontinent that existed during the Paleozoic and Mesozoic eras about 250 million years ago, before each of the component continents were separated into their current configuration.

    The name was first used by the German originator of the continental drift theory, Alfred Wegener, in the 1920 edition of his book The Origin of Continents and Oceans (Die Entstehung der Kontinente und Ozeane), in which a postulated supercontinent Pangaea played a key role.

    ● Configuration of Pangaea

    Pangaea is believed to have been a C-shaped landmass that was spread across the equator. The body of water that was believed to have been enclosed within the resulting crescent has been named the Tethys Sea. Owing to Pangaea's massive size, the inland regions appear to have been very dry, due to the lack of precipitation. The large supercontinent would potentially have allowed terrestrial animals to migrate freely all the way from the South Pole to the North Pole.

    The vast ocean that once surrounded the supercontinent of Pangaea has been named Panthalassa. Pangaea is believed to have broken up about 180 million years ago (mya) in the Jurassic Period, first into two supercontinents (Gondwana to the south and Laurasia to the north), thereafter into the continents as we understand them today.

    ● Formation of Pangaea

    Rodinia, which formed 1.1 billion years ago during the Proterozoic, was the supercontinent from which all subsequent continents, sub or super, derived. Rodinia does not preclude the possibility of prior supercontinents as the breakup and formation of supercontinents appear to be cyclical through Earth's 4.6 billion years.

    Gondwana followed with several iterations before the formation of Pangaea, which succeeded Pannotia, before the beginning of the Paleozoic Era (545 mya) and the Phanerozoic Eon.

    盤古大陸 Pangea(或 Pangaea)

    原文出自於希臘文 Παγγαία

    意思是 全大陸 或 全路地

    中文翻譯成 超大陸 或 泛大陸

    是指在古生代期間全世界的大陸是一大片陸地

    經過幾億年的大陸漂移後 才行成現今的七塊大陸

    地質學家預測世界的大陸

    在二億五千萬年後又會再度形成一個超大陸

    這個超大陸被稱為終極盤古 Pangea Ultima

    而中國神話故事中的人物 盤古

    有人認為是道教中元始天尊的化身

    一般人的認知是開天闢地的人物

    盤古的故事, 較早見於三國時代

    吳國人徐整作的《三五歷記》

    證實了我們中國人的盤古這兩個字

    早在將近兩千年前就出現了

    而當時絕對沒有人知道 超大陸 這種東西

    而 pangea 又是來自希臘文

    所以 盤古大陸 與中國神話 盤古開天闢地

    應該只是一個巧合的同字 並沒有關連

    中國盤古的英文是直接譯音成 Pangu 或 Panku

    約46億年前,在地球剛形成的時候,最巨大的「剛地瓦那古陸(Gondwanaland)」位於現在的南極地區,而其他一些較小的陸塊如勞倫古陸(Laurentia)、波羅的海古陸(Baltica)、哈薩克斯坦(Kazakstania)等等,則散布在地球上的其餘地方。到了石炭紀的末期(約2.9億年前),勞亞古陸(Laurussia)與剛地瓦那古陸發生碰撞,形成「巨大的聯合古陸(the huge landmass of Pangaea)」,當時已經出現了現今阿帕拉契山脈的雛型了。到了三疊紀(約2.45~2.08億年前),現今的大陸都聚在一塊,就是你上面講的一塊大陸,稱作「盤古大陸(Pangaea)」。

    接下來到了侏儸紀(約2.08~1.46億年前),盤古大陸慢慢的分裂,向右分出了一部分的勞亞古陸(即現今歐亞大陸),向左也分出了另一塊勞亞古陸(即現今之北美洲),剩下來的部分被稱作剛地瓦那古陸(包含南美洲、非洲、南極洲、印度及澳洲)。白堊紀(約1.46~0.65億年前),原本的剛地瓦那古陸及勞亞古陸又分的更小塊了,可說是現今陸塊的雛型,南美洲也已經脫離非洲了,洛磯山脈及安地斯山脈在此時已形成。第三紀時(6500~160萬年前),原本仍然相近的各大陸塊逐漸飄遠,慢慢移至現今的位置,不過當時印度、歐洲這兩塊陸塊並未與亞洲連起,喜馬拉雅山脈也只是在抬升階段罷了。
