火山的

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.

Whether it's natural gas drilling unleashing a mud volcano that has engulfed 12 Indonesian villages or the eruption of Krakatoa in 1883 blanketing the world in enough particles to block out the sunshine and lower temperatures by more than a 1.8 degrees Fahrenheit (1 degree Celsius), volcanoes are among Earth's most destructive natural phenomena.

无论是天然气钻探引发的泥火山1喷发淹没了12个印尼村庄，还是1883年喀拉喀托火山爆发产生的微粒覆盖了全球，遮蔽阳光并使温度下降了超过1.8华氏度（1摄氏度）2，火山喷发都是地球最具破坏力的自然现象之一。

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。

长白山天池火山喷发的满语资料是除了汉语、朝语之外另一种极为重要的资料来源，目前己从有关满语神话传说中得到了若干有重要意义的火山与火山信息。

Veined,stockwork and alteration-sheathed gold ores have been found in the area, belonging to four genetic types: the volcanic hydrothermal ores related to early-middle Carboniferous volcanism; subvolcanic hydrothermal ores related to intermediate-acidic porphyry intrusions; hydrothermal ores to the granitic intrusion and dynamo- hydrothermal ores related to regional dynamic metamorphism along the faults .

矿床成因类型有4种：一为火山热液型，其成因与区内早-中石炭世火山作用有关；二为潜火山热液型，与中酸性斑岩体侵位有关；三为岩浆热液型，与花岗质岩浆的侵位有关；四为动力变质热液型，沿断裂带分布于蚀变玄武岩中，系区域动力变质作用的产物。

Type-B Nodule: The source of elements in the nodules comes from slow deposition of the overlying water and the diffusion of the pore water, which comes mainly from the double decomposition reaction of Fe, Mn oxides caused by the oxidation diagenesis of organic material in sediment and its forming process and distribution is controlled by pH in the pore water. There is no corrlation between distribution of the nodules and water depth, topograph.

A型结核主要分布于深海火山沉积环境区，受上覆水Mn〓和Eh制约；B型结核一方面由于在深海火山沉积环境区，受生物作用影响，另一方面在生物沉积环境区，又受火山作用影响，使此类结核的分布与大洋地貌和沉积物的关系不明显；C型结核主要分布在太平洋CCD范围内，受沉积环境上生物和活性有机碳的制约。

The products of Yandunling volcano are trachybasalt.

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.

研究了华北中部太原组含煤地层中火山事件层的岩石学识别标志和分布规律。研究结果表明：含煤地层中广泛发育火山事件层。火山事件层的岩石类型以玻屑凝灰岩、玻屑晶屑凝灰岩和凝灰质中细粒砂岩为主。

Toward the southern rim of the Altiplano, where Bolivia, Chile, and Argentina meet, lava burbles in tall, jagged volcanoes; at their feet, on the shores of what was once a vast lake filling the basin, baby mud volcanoes erupt and hiss through the frozen soil.

朝着阿尔蒂普拉诺南缘前去，玻利维亚、智利与阿根廷在此交会，熔岩在高耸、嶙峋的火山中汨汨作响；火山脚下，曾经填满盆地的浩瀚湖泊的岸边，新生泥火山从冻土中喷发，嘶嘶作响。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
