中生代时期

早古生代时期的喷气喷流型矿床组合和晚古生代&早中生代时期的造山型矿床组合最为重要。

The exhalation-spout type deposits of the early Paleozoic era and the orogenic type deposits of the late Paleozoic to early Mesozoic era are the most important deposit groups .

你们今天的阅读材料讲的是中生代时期的恐龙化石，中生代在六千五百万年前结束。

Your reading for today touched on dinosaur fossils from the Mesozoic era , which ended about 65 million years ago .

在中生代时期，太平洋板块向亚洲大陆板块东缘低角度斜向俯冲，导致中国东部由EW向构造体制转变为NE、NNE向构造体制。

In Mesozoic , due to oblique subduction of Pacific plate toward Asian continent plate at a low angle , the tectonic patterns of Eastern China changed from E-W direction to NE and NNE .

在中生代时期，不仅出露了陆内A型俯冲形成的I-S-A三种类型花岗岩，其演化序列完整、特征典型；

During the Mesozoic period , I-S-A & type granites formed by the intracontinental " A " type subduction are characterized by the complete evolution sequence and typical features .

Orogeny and orogen structure of Dabie Mountain in Mesozoic

揭示了整个东亚地区岩石圈在晚中生代时期遭受了强烈的伸展作用改造，同时伴随着大规模岩石圈减薄作用。

It reveals the lithosphere in the whole east Asia experienced intense extension and lithosphere thinning during late Mesozoic .

多年来，我们都以为，是中生代时期的丰富植物让这些巨型动物繁荣起来。

For years , we have assumed it was the abundant plant life of the Mesozoic that allowed these giants to thrive .

幔源岩浆的底侵及软流圈对地壳的直接加热作用，使上覆地壳发生大规模的岩浆和成矿作用，并导致中国东部中生代时期伸展构造的广泛发育。

The heating from the asthenosphere on the crust subsequently resulted in the intensive magmatism , mineralization , and widespread development of extensional structures in eastern China .

新生代构造现象既是中生代时期构造作用的延续，也是始新世以来复杂应力环境作用的结果。

The tectonic phenomena happened in the Cenozoic are caused by both of the continuity of the Mesozoic tectonic processes and the complexity of Cenozoic stress field .

孩子们在学习中生代时期知识时，可以将虚拟的暴龙和迅猛龙放在家中或教室，甚至可以和这些恐龙自拍合影。

Kids studying the Mesozoic Era would be able to place a virtual Tyrannosaurus or Velociraptor in their home or classroom - and even take selfies with one .

因此，中国东部新生代大陆玄武岩记录了中生代时期太平洋板块俯冲引起华北克拉通古老岩石圈地幔减薄的化学地球动力学。

In this regard , the Cenozoic continental basalts in eastern China are a snapshot of the chemical geodynamics for the thinning of the NCC mantle triggered by the subduction of the Pacific plate during the Mesozoic .

3中生代时期，构造环境复杂，大陆岛弧型为主，三叠纪&侏罗纪期间处于转型期，兼有稳定的被动大陆边缘型特征，早白垩世兼有活动大陆边缘型特征，构造环境更为活化。

The sedimentary tectonic setting during Mesozoic was mainly the continental island arc , and in Trias & Jurassic sometimes was the stable-passive continental margin . And in the period of early Cretaceous the setting was more active , sometimes with the characteristic of the active continental margin .

这些足迹被认为是在中生代白垩纪时期由当时鸟类留下的。

The prints are believed to have been made during the Cretaceous period of the Mesozoic Era , Kim said in a statement .

对它们的研究表明，它们形成于伸展应力体制，是伸展构造的岩石学标志，发生在晚中生代整个地质时期，并认为这一伸展构造由古太平洋库拉板块对欧亚板块的消减作用诱发。

All these features showed that the Late Mesozoic magmatism of SB-China developed in the tectonic setting of extension stress regime which was constrained by the subduction of the paleo-Pacific Kula plate beneath Eurasian plate .
