火山性

The greenstone belt is a typical volcanic-sedimentary formation formed by metabasic-acid volcanic rocks and partly metasedimentary rocks. The bimodal volcanic rocks are mainly tholeiite, which transforms upward into calc-alkali volcanic rock series.

绿岩带为典型的变质基性－酸性火山岩及部分变质沉积岩系构成的火山-沉积建造，火山岩以拉斑玄武岩为主，向上过渡为钙碱性火山岩系列，表现为双峰态型特点。

Victor Gonzalez of the Volcanological and SeismologicalObservatory of Coata Rica stated that the gas is likely to bepreviously trapped methane that was released after the jolting created a fissurein the ocean floor. He also said that it is not known how long the flammablegreenhouse gas would continue to rise.

哥斯达黎加火山和地震观测站的地震学家维多萨雷斯博士指出那些气体可能是原先冰封在海底的甲烷因为地震产生裂缝而释放出来，他也说无法确知这种易燃性的温室气体会继续冒上来多久。

In east adjacent regions Toudaogou of Hami, Zhou Ji yuan found brachiopoda fossil of Early Ordovician in the same stratum of pyroclastic rock with intemediate-basic volcanics: Orthambonites sp., O.

东邻区哈密头道沟，周济元等在相当于火山岩建造的上部层位的火山碎屑岩夹中基性火山岩中发现早奥陶世腕足化石：Orthambonites sp。， O。

Hypogene high thermal or deep source epi-mesothermal condition and it is not only stressed the mantle source simply but also the crust-mantle;②in order to guid ore exploration better the artificial classification of uranium deposits should be broken and uranium ore-forming system strengthened;③much attention should be paid to searching the diabase-hosted rich uranium ore in strongly argillized cataclastic zone;④attention should be paid to the influence of basement of volcanic basin on the uranium ore formation that should be undstood both in feeling and theoretically through the ore propect process;⑤relation of red basin with uranium ore formation can be made clear from analyzing tectonics, paleo-climate and time and it is not only theoretically important but also helpful to uranium ore prediction;⑥crypto explosive pipe is an uranium ore, rich uranium ore host structure and it is the next goal for uranium ore exploration in east China.

摘要文章论述了华东火山岩型铀矿找矿值得重视的地质问题：①铀成矿既可形成于浅源浅成低温条件，也可形成于深源深成高温或深源浅成中低温条件，在强调深源时，不是简单地认为是幔源就可以了，还必须强调壳幔作用的地质过程；②打破人为的&类型&划分，加强&铀成矿系统&的研究，更好地指导找矿；③研究基性脉体与铀成矿问题应注意构造、岩石矿物成分、成因、蚀变与成矿3大问题，注意寻找泥岩化作用强烈的破碎辉绿岩脉中的富铀矿；④火山盆地基底对铀成矿的作用主要是提供铀源，将基底对铀成矿的影响从感性认识推向理性认识，有效地指导找矿；⑤红盆与铀成矿关系可以从构造、古气候及时间分析研究中得出结论，它不仅仅是一个理论问题，而且有助于铀成矿预测；⑥隐爆角砾岩筒是铀成矿、成富矿的重要储矿构造，是华东火山岩型铀矿找矿的新领域。

As there were no plate tectonics on the Moon, these mafic rocks are commonly regarded as products of hot-spot or mantle plume volcanisms.

由于月球上不存在板块构造，因此其基性火山活动是受热点或地幔柱构造所控制的。

The distinctive features of volcanic rocks, especially the spilite, illustrates that mantle plume or hotspot with small scale might be the essential origin of a series geologic events such as the extension of crust, the interval eruption of submarine bimodal volcanic rocks especially the increasing eruption of basic rocks, and the mineratlization of Ashele mine

认为成岩、成矿背景属裂陷拉张环境，火山岩尤其是细碧岩具有五大特殊性，初步提出了热点作用是导致地壳拉张、双峰式火山岩间互喷发、从早到晚基性火山作用趋于增强、以及成矿作用等一系列地质事件的深层次原因的看法

The tensional tectonics observed on the surface of volcanic area are the representation of the expansion.

火山区地表的张性构造与中下地壳的膨胀有关。

At this stage, with a strong role in regional hot arch or basement uplift and erosion. tensional fractures and intense activities such as volcanic activity.

在此阶段，区域性热拱升作用伴随有强烈的基底抬升及剥蚀作用、张性断裂活动及剧烈的火山作用等。

Volcanic eruptions happened: the 1st and 3rd are fissure eruptions of intermediate-basic basaltic andesite and are resulted from the structures of active period, while the 2nd belongs to central eruption of neutral trachyandesite and is derived from the structure of stabilized period.

其间包括3次火山喷发活动，第1次和第3次为中基性玄武安山岩的裂隙式喷发，为构造活动期的产物；第2次为中性粗安岩的中心式喷发，为构造稳定期的产物。

It is possible to establish change of dynamics of eruptions of the volcano Bezymyanniy and necessity of more careful study of its activity.

&&这是有可能建立的变化动态喷发的火山bezymyanniy和必要性进行更仔细的研究它的活动性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
