火山作用的

The iridium layer commonly used to support catastrophism fits into this theory as evidence for the extreme volcanism that would have been produced by the eruption of Larasia and Gondwana.

至于那个支持灾变说的铱异常层，则可能是拉拉西亚和冈纳德万喷发时特别强大的火山作用的产物。

The results show that the kamafugite is mainly a volcanic product of Miocene age.

研究表明西秦岭新生代钾霞橄黄长岩主要是中新世火山作用的产物。

Hence, the study on planetary volcanism is a key part of comparative planetology. Study the volcanism of celestial bodies of Solar system could provide significant knowledge for the understanding of the formation and evolution of the planets, deep and surface processes, metallogenesis, and initiation of life.

对太阳系天体火山作用的对比研究能够提供认识太阳系和行星演化、天体深部和浅部地质作用过程、矿产资源形成以及生命的起源和演化等重要信息，是比较行星学的重要组成部分。

Sub-volcanic rocks include andesitic porphyrite, rhylitic porphyry, cryptoexplosive breccia as well as autobreccia etc.(2) Volcanic lithofacies——through the observation of cores, identification of thin sections and interpretation of well logs and seismic data, there are 8 kinds of lithofacies for the volcanic rocks of Yingcheng Formation are identified: fallout facies, effusion facies, pyroclastic flow facies, base surges facies, lahar facies, eruption-sedimentary facies, subvolcanic facies and extrusion facies.(3) Three types of eruption——i. e. explosion, effusion and surge.(4) Two kinds of eruptive environments——Subaerial (e. g. volcano in Well Shangshen 3) and subaqueous .(5) Three remarkable volcanic apparatus in Shengping-Wangjiatun area——layered, micro-shield and cone volcanoes according to volcanic processes and lithofacies distribution.

次火山岩有安山玢岩、流纹斑岩、隐爆角砾岩及自碎角砾岩等；(2)火山岩相——通过岩芯观察、镜下鉴定、测井与地震资料解释，营城组火山岩中发育8种岩相类型，即爆发空落相、溢流相、火山碎屑流、基底涌流相、喷发沉积相、火山泥石流相、侵出相和次火山相等；(3)火山喷发的形式——有爆发、溢流和涌流三种；(4)火山喷发环境——有陆上(如尚深3井火山)和水下两种；(5)火山机构类型——根据火山作用特点和岩相分布特征，在升平—汪家屯地区识别出三类截然不同的火山机构，即层火山、微型盾火山和渣锥火山。

Since it is a volcanic park, there are lots of illustrations describing the history and the force of volcanism.

由於它是个火山公园，因此就有许多的标示来说明火山作用的影响和历史。

Cryptoexplosive rocks were formed at final stage of multiple phases of intrusion and volcanism of granitoid magma and therefore become the last carrier of ore-bearing magmatic hydrothemal solution.

由于隐爆岩在花岗岩类岩浆多期次侵入和火山作用的最后阶段形成，因而是含矿热液的最后载体。

This paper has mainly dealt, with the structural setting of volcanism, the petrologic and geochemical characteristics of volcanic rocks and its related mineralization along the coast of southeastern China and its vicinity.

本文主要论述中国沿海及其邻侧火山作用的构造背景、火山岩的岩石学和地球化学特征，以及其有关的成矿作用。

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。

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.

矿石类型有含金石英大脉型、石英网脉型和蚀变岩型。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。

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。

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。
