火山

Its volcanic geological formation is complicated, varying from hard lava magmas to weathering pyroclastic debris.

火山形成的地层非常复杂，从坚硬的火山熔岩到松软风化的火山碎屑堆积物都有存在。

This photo was the most exciting volcano experts is that it captures the formation of a volcanic eruption pyroclastic flows, volcanic peaks from the top downward mobility.

这张照片最令火山专家兴奋的是，它捕捉到火山爆发形成的火山碎屑流，从火山峰顶端向下流动。

After comparing the examination result with the common biological indicators, we notice that the organic substances in the samples collected from the mud volcanoes mainly come from land higher plants and the result of the redeposit after washing out the upstream's deposit, this conforms the geographic location in the mountains and the luxuriant plants in the region, hoping this research result can provide reference values for the future land developers, in order to take advantage of the land as much as possible, aw well as a perfect planning and conservation of the mud volcano.

将检测结果与常见的生物指标比对后，发现所取泥火山样品中所含的有机物质主要来自於陆生高等植物及上游沉积物经冲刷后再沉积的结果，这和泥火山的地理位置位於山区且附近植被茂盛是相符合，希望这样的研究结果可提供将来土地开发者参考，对这块土地做最好的利用，并对泥火山做完善的规划与保留。

Volcanic ash in surface sediments around Zhongsha Islands of the South China Sea mainly include three kinds of volcanogenic detritus: that is, brown volcanic glass, colorless volcanic glass and volcanic scoria.

南海中沙近海表层沉积物的轻组分(粒径为63~125μm)中主要包括有褐色火山玻璃、无色火山玻璃以及火山渣等3种火山灰类型。

Young back-arc alkali basalt scoria cones occur east of the Caviahue-Copahue volcanic complex.

杨弧玄武岩火山渣锥碱发生以东Caviahue -科帕韦火山火山复杂。

Based on the subcrustal mantle convection-generated stress field inversed by gravity anomalies, together with its relationship to the Cenozoic volcanism in the plateau, and the mechanism of crustal fracture formation, as well as the numerical results of the evolution of mantle convection beneath the plateau, this paper investigates the deep mechanical mechanism for the formation of a magma transportation channel in the Tibetan Plateau.

为了研究火山形成基本要素―岩浆运移通道的形成，基于重力异常反演的青藏高原下地壳底部的地幔对流应力场，结合地壳破裂形成机理和对流应力场与青藏高原新生代火山分布的关系，以及青藏高原下地幔对流演化的数值模拟结果，分析了高原火山岩浆运移通道产生的深部力学机制。

Based on reading documents, the common principle of volcanic rocks thermoluminescence

与热释光测年有关的火山岩在广义上应包括火山熔岩、火山喷发物及与火山喷发有关的烘烤层。

He Youngest Toba Tuff eruption was the greatest single volcanic event which occuned in the Quaternary, dated back to 74 ± 2 ka., and bad important impacts on global environmental and climatic changes.

oba火山活动是第四纪最大的火山事件，其中最年轻的约0.074Ma的火山活动被称为YTT事件。

The results showed that the trass in this area is feasible as a kind of more ideal natural lightweight aggregate, and the trass concrete can reach the grade of intensity the structure component needs.

结果表明，该地区的火山渣作为一种比较理想的天然轻骨料是可行的，用此火山渣配置的火山渣混凝土能够达到结构构件需要的强度等级。

The two volcanic materials are similar but are also different ①the partition mode of rare-earth element is similar to that of the basalt.②the increase content of the rare-earth element content in transitional layer shows that it enrichs in this segment due to the volcano events. Moreover, the comparability of the partition mode shows that the volcano-genic materials and the basalt are of the same source.③low Eu anomaly different from the high Eu anomaly of medium-acidic tuff in Meishan section, that show that their formation is different④there are plentiful basalt detritus.⑤there are enrichment of the Ti element.⑥the lower content of siderophile element of Ni and Co, especially in the transitional layer, show that there were not extraterrestrial events and big scale basic or ultrabasic volcano eruption events in this area. These characteristics show that the sedimentary source of Xuanwei Formation and Kayitou Formation is basalt.

1稀土元素配分模式与玄武岩类似；(2)稀土元素含量在异常层的增加反映了火山事件导致了它在该段地层中的富集，而配分模式的相似性反映了火山物质来源与玄武岩具有同源性；(3)低"Eu"异常区别于煤山剖面的中酸性凝灰岩高"Eu"异常模式，说明界线粘土岩成因也不同于煤山剖面的界线粘土；(4)大量的玄武岩岩屑；(5)Ti元素的富集；(6)亲铁元素Ni和Co含量较低，特别是在界线异常层含量降低，表明本区在界线处可能并不存在地外事件和大规模基性、超基性火山喷发事件，这些特征反映本区宣威组和卡以头组物质来源主要为玄武岩。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
