2. tazhong ancient uplift originated from normal fault in paleozoic, hydrocarbon formed in ordovician period, structure reverse made tazhong uplift form from the middle ordovician period to the late ordovician period, and it provided geologic background for the deposit of silurian - devonian stratum. tazhong uplift formed at the end devonian, ancient reservoir was destroyed and asphaltum sandstone formed, structure deformation more destroyed ancient reservoir in early permian, after then the major of structure deformation is regulation
塔中隆起源於早古生代拉張背景下的正斷層，寒武-奧陶紀為其烴源巖形成的重要時期；早奧陶世末-晚奧陶世末的構造反轉是塔中隆起的主要形成期，同時也為志留系形成地層及復合圈閉提供了古地理背景；志留?泥盆紀塔里木盆地南北緣均轉為活動大陸邊緣，形成了大量的斷裂和不整合；泥盆紀末塔中鼻狀隆起基本定型，古油藏遭受破壞，形成了瀝青砂巖；早二疊世晚期的構造變形使古油藏遭受進一步的破壞；二疊紀后構造變動主要以調節為主。Taowan conglomerate ; seismism ; early cambrian period ; luonan shaanxi

在寒武紀至中奧陶世早期，東秦嶺北部二郎坪海槽的寒武紀放射蟲和早奧陶世牙形石與東秦嶺南部浙川陸棚北部的寒武紀三葉蟲、早奧陶世牙形石和頭足類屬華南生物省，而浙川陸棚南部的寒武紀三葉蟲和早奧陶世牙形石屬于華南生物省，兼有華北生物省分子。Eight aspects related to the study of early precambrian metamorphic stratigraphy are dealt with in this paper : general situation of the study ; complexity of the stratigraphy and difficulties of the study ; thoughts and methods of the study ; division of rock suite, rock group and complex rock ; researches on important regional discordances ; types and characteristics of protolith and recovery of palaeoenvironment ; correct differentiation of the metamorphic strata, ttg rock system and other metamorphic plutonic rocks ; determination of the ages of the metamorphic strata
摘要主要論述了與早前寒武紀變質地層（學）有關的8個方面的問題：早前寒武紀變質地層的研究概況；早前寒武紀變質地層的復雜性和研究難度；早前寒武紀變質地層研究的思路和工作方法；早前寒武紀變質巖石地層單位巖群、巖組和雜巖的劃分問題；重要區域性不整合的研究；鑒定變質地層的原巖類型、巖石性質和恢復古環境；正確區分變質地層和ttg巖系以及其他變質深成巖；變質地層時代的確定。Early precambrian basement and metallogenetic series in eastern heilongjiang province
黑龍江省東部早前寒武紀基底及礦床成礦系列劃分This investigation placed the last common ancestor of bilaterian animals at a much younger date, though still older than the cambrian explosion, somewhere between 573 million and 656 million years ago
這項研究把兩側對稱動物最後的共同祖先，定置於較晚的時間，不過仍比寒武紀大爆發的時間要早，大約是6億5600萬年至5億7300萬年前之間。Follow - up studies using the molecular clock produced estimates for this split that varied significantly, ranging from as old as one billion years ago to as young as just before the cambrian period
后來使用分子時鐘來估算分支時間的研究結果，差異都很大，可能早至10億年前，晚至寒武紀即將開始時。In fact, over 300 million years earlier than the world of dinosaur ( dated back to 500 million years ), earth had witnessed the first era of colorful life world ? cambrian period
《侏羅紀公園》重現了1億多年前的侏羅紀夢幻般的恐龍世界，其實，早在恐龍世界之前3億多年（距今約5億多年） ，地球生命就已經開辟了多彩多姿的生命世界第一個紀元? ?寒武紀。And, at several spots on the planet, the ediacaran lagerst ? tten, named after the ediacara hills of australia where the first example was found, harbor strange precambrian soft - bodied fossils and animal burrows, including evidence for early bilaterians
而分佈在地球上數個地區的艾迪卡拉特異埋藏點（命名自首次發現的澳洲艾迪卡拉山） ，裏面藏有奇妙的前寒武紀軟體化石與蟲穴，包括早期兩側對稱動物的證據。Their results, published in 1996, postulated that bilaterians diverged from more primitive animals deep into the precambrian era, as much as 1. 2 billion years ago
他們的結果發表於1996年，其中推測，早在12億年前的前寒武紀，兩側對稱動物便已經從較原始的物種分支出來。The latest studies show that these rocks are older than the ediacara biota, most likely 580 million to 600 million years old, and thus that the microfossils they contain lived 40 million to 55 million years before the cambrian
最新研究顯示，此沉積比艾迪卡拉生物群還早，很有可能介於6億到5億8000萬年前，也就是說，裏面微化石的生存年代比寒武紀還早了4000萬到5500萬年左右。分享友人
