火山

The volcanic earthquake mainly has two kinds: One kind when is volcanic eruption, because the rock magma impact earth's crust or causes the earthquake which the local area rock layer occurs distorts and dislodges causes.

火山地震是由火山爆发而引起的。火山地震主要有两种：一种是火山爆发时，由于岩浆冲击地壳或使局部地区岩层发生变形和变位而引起的地震。

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）。

Such sights are uncommon as many eruptions simply see ash and rock blasted into the sky.

这种景观对于斯特龙博利火山来说不是常见的。以前斯特龙博利火山爆发时只是出现火山灰和岩石喷上天空的景象。

Based on the analysis of deposit genetic type in the metallogenic belt,the metallogenic series has been put forward,that is volcanic-subvolcanic hydrothermal and porphyry type Au-Cu and Mo-Pb-Zn-Ag metallogenic series .

在分析成矿带内不同矿床成因类型的基础上，建立了该成矿带的成矿系列：火山、次火山热液-斑岩型金铜及钼铅锌银成矿系列。

Calderas , large basin-like depressions , are formed when a violent eruption blows the top off of an existing cone or when the center of a volcano collapses .

破火山口，巨大的，盆地状的洼地，是当猛烈的爆发将原来存在的火山锥吹飞或当火山中心坍塌时而形成的。

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。

Several tens of superlarge hydrothermal gold deposits related to volcano subvolcanic rocks have been defined in the world since 1980s. It is of great importance, both economically and theoretically, to study this type of gold deposits. The newly discovered Jinchang gold deposit, Heilongjiang Province, is one of this type of gold deposits, which is hosted by breccias bodies that are associated with volcano-subvolcanic rocks. More than 30 t Au resource has been proved after preliminary exploration by the 5〓 Geological Party of Gold Headquarter.

After the volcano exploded 18 hours, volcanic chippings buried the city of Pompeii. The deepest is about 19 meters. In this way Pompeii suddenly disappeared in its top period of material civilization.

火山爆发18个小时后，火山碎屑将整个庞贝城掩埋，最深处竟达19米，庞贝就这样突然消失在它物质文明的巅峰期之中。

The clay mineralogy composition and clast composition difference between different section or different levels in one section may result from variable intension of the volcanism, distance from the volcanism center and paleogeographical location.

同是深水相P-T界线剖面附近的黏土岩以及同一剖面不同层位的黏土岩中的黏土矿物和碎屑物质存在较大的差异，其原因可能是与火山作用的强弱、离火山活动中心的远近以及所处地理位置有关。

There are 4 end members of volcanic clasts, including catapult airfall, ejection airfall, base surge and volcanic clasts flow.

与火山作用有关岩相有4种端元的火山碎屑岩相：弹射坠落爆发空落相、喷射降落爆发空落相、热碎屑流相和热基浪相。
