- One of the most noticeable features of the Middle Miocene rock layers was their periodicity. 中新世中期的岩层,最显著的特徵之一,就是这些岩石所呈现的周期性。
- The result showed that there were two hydrocarbon-charging times in the Middle Miocene and the Late Pliocene. 研究表明,柴西南区有两次主要的油气充注期:中新世中期和上新世末期;
- The strongest indications that freshwater dominated the landscape during the Middle Miocene emerged from the abundant fossils entombed in the outcrops. 淡水主宰了中新世时期的地貌,最有力的证明来自于埋藏在露头中的大量化石。
- The main hydrocarbon source rocks for the basins consist of lacustrine mud and lower coastal plain sediments from Oligocene to Middle Miocene. 这些新生代沈积盆地构造类型多、面积大,新生界巨厚,邻近陆坡的大陆架十分宽广,塑造了多个三角洲,是重要的含油气资源区。
- Therefore, the existence of the late Cenozoic aeolian deposit demonstrates that the middle and west parts of the Tibetan Plateau have been dry since the middle Miocene time. 因此,中中新世以来湟水流域风尘堆积物的存在可能表明了青藏高原中西部在那时已经较为干旱。

- Instead we think that the rock samples I collected from the Middle Miocene, representing the period from roughly 16 million to 10 million years ago, are relics of a primarily freshwater environment. 相反的,我们认为我所?集到的中新世岩石样本,是1600~1000万年前原始淡水环境的遗物。
- Among them, one hiatus is at the depth of 325 cm, where buried polymetallic nodules about 10 millimeters thick are found. It is occurred from Middle Miocene to Late Pliocene. In C|C (Clarrion and Clipperton )zone, this hiatus is extensively presented. 该柱中存在 4 个沉积间断, 其中在 325 cm附近层位有一厚约 10 cm 的多金属结核层,此界面为中中新世至晚上新世的沉积间断,它在 C C区内普遍存在, 持续时间长, 分布范围广。
- The Tertiary in the Kumkol basin,Xinjiang,may be divided into the Oligocene Huatiaoshan Formation,middle lower Miocene Hongshiliang Formation,middle Miocene Fengchenkou Formation and Pliocene Jiantuliang Formation. 新疆库木库里盆地第三系可划分为渐新统花条山组、中新统中下部红石梁组、中新统中部风尘口组及上新统碱土梁组。
- Abstract: The lacustrine Early to Middle Miocene Shanwang Formation contains an exceptionally wellpreserved biota including insects, plants, and vertebrates that has been subject to intense study. 文章摘要: 山东山旺中新世山旺组湖相沉积中富含保存精美的古生物化石。对于湖相沉积中的昆虫、植物和哺乳动物化石,前人已经做了大量的研究工作。
- BY THE END of the middle Miocene, roughly 13 million years ago, we have evidence for great apes in Eurasia, notably Lartet's fossil great ape, Dryopithecus, in Europe and Sivapithecus in Asia. 1300万年前,中新世中期结束,我们在欧亚大陆上找到了大猿化石,特别是拉特首先描述的欧洲大猿(林猿),以及亚洲的西瓦猿(Sivapithecus)。
