喷发

The rock assemblage and geochemisty of the sedimentary rocks indicate that the Xiong'er Group formed in a passive continental margin and it was mainly a marine facies when lava erupted. Therefore the paleogeographic environment of the Xiong'er Group evolved from continental facies to marine facies then to continental facies again.

This paper discusses the merits and shortcomings of the estimation methods previously used for the degree and mass of magma degassing in the volcanic eruption. On the basis of these methods, the authors propose a new petrological method for the estimation performed at various stages in the process of volcanism, and illustrate the detailed steps as exemplified by the Jingpohu Holocene volcanic eruption.

Its volcanoes do not have the explosive oomph of some eruptions in the "ring of fire" around the Pacific, such as those of Tambora and Krakatoa in the 19th century, let alone the prehistoric eruptions of Taupo, in New Zealand, and Toba, in Indonesia, which were large enough to have severe, if short-lived, effects on the global climate.

其火山群没有环太平洋地区&火圈&般的爆发力，例如19世纪的坦博拉火山和喀拉喀托火山，更不能和史前时期新西兰的陶波火山喷发和印度尼西亚的Toba火山相提并论。这些火山喷发规模宏大，即使持续时间短，也足以严重影响全球气候。

桃园-红星方向和大平房以南两个喷发源所喷发出的火山岩相互交织叠置于地层之间。

In about 25,000,000 year, the Changbai Mountain area experienced 4 volcanic eruption activity, the basaltic magma embarked from the upper mantle, upwelled unceasingly along the earth's crust in giant crevasse, spouted the surface by the huge energy (in geology to be called crevasse type volcanic eruption).

在大约2500万年的时间里，长白山地区经历了4次火山喷发活动，玄武岩浆从上地幔出发，沿着地壳中的巨大裂隙不断上涌，以巨大的能量喷出地表（地质学上称为裂隙式火山喷发）。

The 3-D pattern is a good reference to study mechanism of volcano eruption, m agma movement and prediction and preparedness of volcano.

本文所 得的三维速度层析成象结果，可为研究腾冲火山喷发机理、岩浆运移系统动力成因以及火山喷发预测与预防等方面深入研究提供重要参考。

The STEREO craft is the first to measure the speed and direction of solar ejections, such as the one pictured, that are headed toward Earth.

STEREO项目的太空飞船是首个用于测量太阳风喷发速度和朝向的太空探测器，如图中所显示的这次喷发，其方向就指向地球。

There was a strong correlation between the eruption and the lahar or flood around Tianchi volcano. Flood or lahar influenced the ancient people along the Nenjiang riverbanks 460 km away from Tianchi volcano.
