precambrian,英語單詞,主要用作名詞、形容詞,作名詞時譯為“前寒武紀;前寒武層”,作形容詞時譯為“[地質] 前寒武紀的”。
前寒武紀(Precambrian)是地質年代中,對於顯生宙之前數個宙(Eon)所使用的非正式名稱,原本正式的名稱是隱生宙(Cryptozoic eon,其後來被拆分成冥古宙、太古宙與元古宙三個時代)。1930年,G.H.查德威克將地史時期劃分為兩個階段——寒武紀以前稱為隱生宙,寒武紀迄今稱為顯生宙——作為地質年代的最高級單位...
前寒武紀構造(Precambrian tectonics)是指顯生宙以前的構造及其演化。地球在46億年前生成,有硬體保存下來的化石到近6億年前的顯生宙才出現,因此它代表地球85%的歷史。整個前寒武紀大致可分成三個階段:①從46億年前到全世界已知最古老的38億年英雲閃長質岩石露頭之間,地球形成的最初8億年沒有地質記錄存留下來...

無生帶 無生帶(Precambrian time)指太古代之前的地質時代。時間從地球形成(約45-46億年前)至太古代之初(38億年前)。這段時間是缺乏現實資料可考的時代,人類對其研究極少。一般認為此時生命物質尚未形成。
地質年代從古至今依次為:前寒武系(Precambrian)、顯生宙(Phanerozoic)。前寒武系細分為:冥古宙、太古宙、元古宙;顯生宙又分為:古生代、中生代、新生代;古生代分為:寒武紀、奧陶紀、志留紀、泥盆紀、石炭紀、二疊紀;中生代分為:三疊紀、侏羅紀、白堊紀;新生代分為:古近紀、新近紀、第四紀。地質年代命名 年表...
它組成了中、北非洲的大部分。時代結束 而當成冰紀邁向末期時,正處於巴倫澤冰期 (Baranger glaciation) (馬林諾冰期 Marinoan glaciation),因積留在岩石里的碳13 同位素產生變化,而結束了成冰紀的年代。成冰紀時期是屬於前寒武紀 (Precambrian) 里元古宙晚期的一部份, 其順序排列在埃迪卡拉紀之前。
前寒武時代 Precambrian era,PreCambrian era,最古的地質年代。從約46億年前地球誕生開始約經歷40.3億年。以前曾把這個時代分為太古代和元古代,但由於近年隨著質量分析儀器的改進,使用同位素方法測定年代的進展,認為這樣分為兩代沒有意義,而改變了前寒武時代的繼續期間的見解。這個時代的地層是由花崗岩、變質岩,...
