熔岩

The Pacaya volcano started erupting lava and rocks on Thursday afternoon, blanketing Guatemala City with ash and forcing the closure of the international airport.

帕卡亚火山开始喷发的周四下午熔岩和石块，火山灰铺天盖地的危地马拉城，并迫使国际机场关闭。

Fluorites formed in uranium mineralization period in the Zoujiashan and Shazhou uranium deposits have ε〓 values from -6.7 to -8.3 and I〓 values from 0.7145 to 0.7204, similar to their host rocks (porphyroblastic lava and sub-granodioritic porphyry) which have ε〓 values from -6.2 to -9.4 and I〓 values from 0.7121～0.7192. On diagram of ε〓- t, the fluorites and host rocks plot in similar area within the evolution field of the basement rocks at Xiangshan. The lead isotopic compositions of pyrites formed in uranium mineralization period plot as a line on diagram of 〓Pb/〓Pb vs.〓Pb/〓Pb. The host rocks plot at the lower value end. Calculation based on the slope of the line and the mineralzation age yields age of 144Ma for the geological body which provided uranium for the mineralization.

邹家山和沙洲铀矿床成矿期萤石的ε〓值(-6.7～-8.3)和I〓值(0.7145～0.7204)与赋矿围岩(碎斑熔岩及次花岗闪长斑岩)的ε〓值(-6.2～-9.4)和I〓值(0.7121～0.7192)相似，在ε〓-t图上，成矿期萤石数据点的投影范围与赋矿围岩的基本吻合，且均落在相山元古宙基底演化域范围内；成矿期黄铁矿的铅同位素组成在〓Pb/〓Pb-〓Pb/〓Pb关系图上呈线性分布，而火山岩的铅同位素组成位于此相关线的低值一端；利用异常铅线的斜率及成矿年龄计算出富铀地质体的形成年龄为144Ma，这与赋矿围岩的成岩年龄(135～140Ma)非常接近。

Within a year, these worms grow to almost a full meter, and encase themselves inside a hard crystalline cask to pupate. Within a month, they emerge as a six-legged flea.

一年之内，这些蠕虫会成长至将近一公尺长，并将自己变成一个坚硬透明的蛹；一个月之内，它们便会羽化为六足的熔岩蚤。

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。

More mountains; bluish beauties never attainable, or ever turning into inhabited hill after hill; south-eastern ranges, altitudinal failures as alps go; heart and sky-piercing snow-veined gray colossi of stone, relentless peaks appearing from nowhere at a turn of the highway; timbered enormities, with a system of neatly overlapping dark firs, interrupted in places by pale puffs of aspen; pink and lilac formations, Pharaonic, phallic,"too prehistoric for words"; buttes of black lava; early spring mountains with young-elephant lanugo along their spines; end-of-the-summer mountains, all hunched up, their heavy Egyptian limbs folded under folds of tawny moth-eaten plush; oatmeal hills, flecked with green round oaks; a last rufous mountain with a rich rug of lucerne at its foot.

山叠山；淡青色的美景我从未看清楚，一山接一山之后出现了人迹炊烟；东南部，重峦叠障；覆着雪脉的摩天灰色石碑，连绵的尖峰在高速公路的转弯处突然现露出来，幽深的林阵，与整齐的暗黑色枞树完全重叠，又被白杨树柔白的烟雾切断；粉色和淡紫色的组合，是属于法老的，是属于阳器崇拜的，&太是史前的了叫人无话可说&；黑色熔岩山岗；早春的山峦，沿山背到处是幼象的细毛，—夏末的山峦，全都驼着背，它们沉重的埃及式肢体摺叠在黄褐色厚绒布纹里；燕麦片山群，点缀着绿色的圆椽树；最后一座红山，山脚布满一片繁茂的紫花苜蓿。

The studies on mineral geochemical for Erdaogou gold deposit located in the west part of Liaoning province indicate that it is characterized by low temperature mineral association such as pyrite, chalcopyrite, galena, sphalenite, telectrum, quartz, seriate, calcite, adual etc.

通过对二道沟金矿床矿物学的详细研究和对比，表明该矿床低温热液矿物组合和低温热液蚀变十分发育；与典型的冰长石-绢云母型浅成热液金矿的矿物组合十分相似；其应属于与流纹熔岩及其火山碎屑岩密切相关的浅成热液型金矿床

Studies of petrology and petrochemistry indicate that such suit of volcanic rocks dominated by lattite belongs to shoshonite series to potassic alkali basalt series. Considering the stability of rocks and their associations, gentle stratum occurrence, fresh degree of rocks and comparatively clarity of horizons. this potassic volcanic stratum distributed over the Sailipu area is named as Sailipu Formation, and the age of which is early middle Pleistocene of Quaternary.

岩石学、岩石化学研究表明，这套火山岩是以安粗质熔岩为主的钾玄岩系列－钾质碱性玄武岩系列火山岩，岩石类型及岩石组合稳定，岩层产状平缓，岩石新鲜，层位相对清楚，故将其命名为赛利普组，属第四纪早－中更新世。

Lava was seen spewing down the mountainside but officials say it doesn't threaten any cities.

可以看到熔岩从山边流下，但是官方说这还没有对城市造成威胁。

For 24 days, the volcano gave its most dazzling show in a decade, spewing rivers of lava and fountains of fire.

24天，火山爆发了最耀眼的显示，在十年内，喷涌的熔岩河流和喷泉的，小心防火。

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。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
