火山

Considering near field observation and parameter interp retation of source mechanics, the authors think that the low or higt velocity be lts in Tengchong volcano areas are closely related to the magma activities of th e volcanoes.

根据本文成析成象结果，结合数字化近场地震观测资料及震源力学参数特征解释，分析认为，腾冲火山区地壳不同深度存在的低速带或高速带均与火山作用的岩浆活动有密切关系。

Xiangshan volcano-intrusive complexes is the wall rock of the biggest volcanic-rock uranium ore deposit in China, and the main body is rhyolitic porphyroclastic lava, accompanied by hypahyssal or ultra-hypabyssal intrusive rocks such as dacite-porphyry and granite-porphyry Jiulongzhang volcano-intrusive complexes are dominantly rhyolitic welded tuff, accompanied by dacite-porphyry and quartz monzonite-porphyry, and so on, and the uranium resources are being assessed.

相山火山－侵入杂岩是华南地区最大的火山岩型铀矿赋矿围岩，其主体岩石为流纹质碎斑熔岩，浅成－超浅成侵入岩有英安斑岩、花岗斑岩等；九龙嶂火山－侵入杂岩的铀资源潜力尚待评价，主体岩石为流纹质熔结凝灰岩，浅成－超浅成侵入岩有英安斑岩、石英二长斑岩等。

Shasta is a volcano, it means there are lots of volcanic activities nearby.

由於Mt。 Shasta是座火山，表示附近有许多的火山活动。

Oulituozi, where the fierce volcanic activities occurred in Eocene of Cenozoic, is located in the middle eastern sag of Liaohe Basin. The main litholigies are basalt, trachyte and tephra.

欧利坨子位于辽河盆地东部凹陷中段，是新生代古近纪火山活动非常强烈的地区，主要岩性为玄武岩粗面岩和火山碎屑岩。

The effect of 9 volcanic eruptions with VEI ≥ 4 on solar radia tion and air temperature in Xinjiang is analyzed based on the data of air timperature from 16 meteorological stations and the data of solar radiation from 8 solar radiation stations in Xin jiang.

本文利用1961－1993年新疆16个气象站气温资料和8个日射站的辐射资料，分析了火山爆发指数VEI≥4级的9次强火山爆发对新疆太阳直接辐射和气温的影响。

Their lithologic types are dominated by vitric tuff, vitric crystal tuff and medium-fine tuffy sandstone, and their genetic types mainly belong to complicated type of the airborne-water-carried and the airborne type.

火山事件层的岩石类型以玻屑沉凝灰岩、玻屑晶屑沉凝灰岩和凝灰质中细粒砂岩为主。火山事件沉积的成因类型以空降－水携复合型和空降型为主。

Spectrum analyses have been done to 24 microseisms occurred in Tengchong volcan o areas and nearby by digital data recorded at mobile seismic stations.

利用腾冲火山地区流动数字化地震台网的微震资料，对发生于火山区内及附近地区的24个微小地震事件进行波谱分析。

From the small number of impact craters that appear on Martian lava flows, one can estimate that the planet was volcanically active as recently as a half-billion years ago –and may be active today.

太空探测照片显示火星表面存在大型火山，从火星上镉岩层流中出现的小数量的环形山来看，我们可以估计5亿年前此星上还有火山运动——甚至今天还在运动。

Since development of volcanic layers and volcanic mounds in basement in Tazhong area, using seismic exploration is usually difficult to acquire better seismic data in the interior of vocatine and below(mainly caused by shield of volcanic layer), but using MT exploration may not produce such problem, because the electromagnetic wave does not suffered from the shield of higher resistance layer; especially the volcanite has the feature of higher magnetic susceptibility and impedance, which provides excellent c...

由于塔中地区的火山岩层及基底火山岩丘发育，采用地震勘探方法通常难以在火山岩内部及其以下获得比较好的地震资料(主要是火山岩层的屏蔽作用)，而利用MT勘探则无此问题，因为电磁波不受高阻地层屏蔽，尤其是火山岩具有高磁化率和高电阻率的特征，从而为在该区应用大地电磁和磁力方法识别火山岩薄层及基底火山岩丘提供了得天独厚的条件。

Being downwind from a volcano is to be avoided, where ash fall is heaviest, disbursing into the atmosphere thereafter.

要避免在火山的下风口，因为此处的火山沉降物是最多的，之后还会飘进地球大气层。
