查询词典 volcanism

This was interpreted as follows: shortly after its formation Dione was active. Some processes ice volcanism?

以下是一些解释：Dione形成后不久是十分活跃的，一些变化过程使Dione的大部分换了新颜，顺半球保留了条纹的地形，也可能在整个地表都有。

Volcanism is thought to have created the domes, although the precise mechanism remains unknown.

The four types of sequence interfaces embody ten types, such as paleocrust of weathering, drossy layer, river rejuvenation, palaeokarstification surface, scouring and erosional surface of slope gravity flow, erosional surface of basin turbidity current, volcanism surface, transfer surface of lithologic characters or lithofacies, onlap surface and maximum flooding surface.

以此为基础，将右江盆地泥盆系—中三叠统划分为6个二级层序和49个二级层序。

Because of the continual effect of volcanism from the end of Tertiary to the Holocene, it forms many kinds of volcanic physiognomy. Especially the volcano crater lake and fulgurite lake which formed after the volcano broke forth to provide the negative physiognomy for the swamps development.

由于该地区从第三纪末直到第四纪全新世多次受到火山活动的影响，形成东北地区多种多样的火山地貌，特别是火山喷发后形成的火口湖和熔岩堰塞湖。

At the stage of geosyncline, the huge thick sal geo synclinal structural layer would be formed by volcanism and weathering deposition; the Caledonion granites would be form ed by remelting or mix-melting.

地槽阶段，火山作用及风化沉积作用等形成了巨厚的硅铝质地槽构造层；重熔或混熔（包括混合作用和/或同化混染作用）形成了加里东花岗岩类。

Geological and geochemical features suggest that the bimodal volcanism took place in rift setting of continental margin, basic magma originated from not strongly depleted mantle, and rhyolite derived from the original melt formed by partial melting of granulite facies orthometamorphite in lower crust.

地质和地球化学特征指出吕梁群上部的双峰式火山岩形成于大陆边缘的裂谷环境，其中的玄武质岩浆起源于亏损程度较低的上地幔，并受到了陆壳物质的混染。酸性端元是由下地壳麻粒岩相正变质岩的部分熔融形成。

Flash heat, volcanism, lightning, wind, and waves all renew the material world.

快速加热、火山活动、闪电、大风以及海浪都是能够让物质世界焕然一新的东西。

Tectonic activities and volcanism in the basin have an influence on hydrocarbon generation of kerogen and its change.

盆地构造活动和火山作用可以促进干酪根的成烃转化。

Such sedimentation followed a 20~25 Ma-long period of Tiaojishan/Lanqi volcanism and was accompanied by plutonic emplacement (ca.158~141 Ma) in some Yanshan areas.

土城子组/后城组的沉积是紧随着在燕山部分地区发生的，持续了20~25Ma的髫髻山组/蓝旗组火山及岩浆活动。

Taking the eastern sag of the Liaohe basin where coal, oil and gas resources coexist and the Wangying borefield of the Fuxin basin where coalbed gas was first discovered, researched and developed in China as examples, we systematically discuss the control of volcanism on the lateral and vertical distribution of brown coal, flame coal and gas coal in the third member of the Paleogene Shahejie Formation and on the gas source conditions of each coal region. Both the methane released in the process of regional plutonic metamorphism and the additional methane generated by contact metamorphism are calculated. The physical properties and storage capacity of the coal beds changed greatly due to the formation of blackcoal and highlymetamorphosed crevice coal from igneous intrusion. The sealing capacity of intrusions with various occurrences such as dikes is highlighted.

以煤、油、气共生的辽河盆地东部凹陷和我国首次在矿井中发现、研究、开发煤层气藏的阜新盆地王营井田为例，系统地阐述了火山活动在古近系沙河街组三段对褐煤、长焰煤和气煤在平面及垂向分布的控制，进而导致各赋煤区气源条件的不同；估算了王营井田在区域深成变质过程释放甲烷气的基础上，接触变质作用所形成的附加甲烷量；指出由于岩浆侵入形成了天然焦和高变质裂隙煤，使煤层物理性质及储集能力发生了大的变化；强调了岩墙等不同产状的岩浆侵入岩体对煤层气的封闭作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
