火山岩

The Lower Cretaceous Yingcheng Formation in which the volcanic rocks are high in content and widely distributed was developed at the late stage of rifting.

徐家围子断陷是松辽盆地内的一个较大的中生代断陷，下白垩统营城组发育于断陷晚期，分布面积广，火山岩发育。

There are three sedimentary cycles developed in each basin, relating to three times of deepening and shoaling of the lake.

每个盆地基本上都发育三个沉积旋回，经历了三次湖盆加深、变浅的过程，后期多被火山岩覆盖。

When the magma cools and solidifies,volcanic rock. Reversals of the field give rise to a series of magnetic

岩浆冷却并凝固下来后，地磁场的方向和磁极被保留在磁化了的火山岩中。

Since then, it has emitted ash and spewed lava but remained restless.

从那时以来，就只有火山灰与喷出的火山岩，人们的不安。

In addition, significant 230Th enrichments disprove the possibility of recent (50 ka) fluid addition from subducted Pacific sediments as a mechanism to generate the Holocene lavas in NE China.

同时表明，近期（50 ka）来自俯冲的太平洋沉积物的流体对中国东北全新世火山岩的产生是一种重要机制。

As a result of Pacific plate subducting toward Eurasian plate, a long acidic volcanics belt formed which extends from northeast to south of China and covers nearly 1 million km〓. This belt is also an important area of precious and nonferrous metal deposits in China.

受太平洋板块向欧亚板块俯冲作用的影响，我国从东北的大兴安岭经过山东、江西、福建、广东一直到广西境内，形成了一条中新生代酸性火山岩带，分布面积近100万km〓，是我国重要的金、银贵金属及铅、锌、铜等有色金属矿床分布区域。

Mandula area is situated in junction belt between Siberia and North China plates in Damaoqi, Inner Mongolia 1∶50000 regional investigation can recognize many traces of plate action recently years Such as tectonic melange belts, ocean crust remant fragments, island are volcanic and are-rear basin sedimont act They recorded a whole precess or plate action the area from extension, convergence to collision act from Carboniferous to Permian period This result has offered rich, reliable of geological info...

内蒙古达茂旗满都拉地区位于西伯利亚板块和华北板块的接合带。近年来的1∶ 5万区调识别出本区存在着诸多板块活动遗迹，如构造混杂带、洋壳残片、岛弧火山岩、弧后盆地沉积等，记录了在石炭纪至二叠纪这段地质时期内本区从拉张、收敛到碰撞等板块活动的全过程。这一成果，为研究内蒙古北部地槽区的板块活动历史提供了丰富而可靠的地质资料

Eight square miles of volcanic rock and Ash.

8平方英里大小遍布火山岩和火山灰

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
