I am a delicate little drops of water, I have a wet also small, plump body, I like the most insignificant thing in the world, let a person do not pay attention to.
The sun to see my friends and I play tired, we go home, I went back to the blue sky with the guys in dad's arms, we huddle together in the bright sunlight for sleeping. After a while, the dark clouds sister called me and holding our clouds elder brother to play, she said, pulling us out. At this time, we saw the earth a piece of dry, no rain for a long time, my friends and I rushed to jump to the earth mother's arms, drifting in the wind, we accepted our the earth that makes her alive. Has sprouted leaves, flowers, birds, schools of thought contend.
To suburbs, starts, the peach blossom, white and pink and plough flowers, as well as the vast expanse of golden rape, drew a rainbow of black and yellow bee and butterfly, they are flying in the flowers to collect nectar, create beautiful tomorrow.
In the "rural" flowers, in the open full of flowers on the hillside, children chasing play on the lawn, all kinds of kites in the blue sky fly freely. Here, everywhere is a piece of laughter, the adults sitting under the shade of the tree, chat over a cup of tea, a harmonious picture.
People praise the beauty of the spring, the beauty of a flower, who would have thought this is the point of light rain we are small and humble credit? We this group of little angel fell from the sky, in order to make the motherland radiant, we do not hesitate to life, let the earth the awaken of spring march, massif, LuLuCongCong, crops harvest year after year, people always laugh.

堆晶岩捕虏体矿物学特征
看来2楼的学多了外文把中文给忘了。楼主的意思是用英语介绍下瑞士这个国家,只要初中水平就行了,不要太复杂。
Switzerland, in central Europe, is the land of the Alps. Its tallest peak is the Dufourspitze at 15,203 ft (4,634 m) on the Swiss side of the Italian border, one of 10 summits of the Monte Rosa massif. The tallest peak in all of the Alps, Mont Blanc (15,771 ft; 4,807 m), is actually in France. Most of Switzerland is composed of a mountainous plateau bordered by the great bulk of the Alps on the south and by the Jura Mountains on the northwest. The country's largest lakes—Geneva, Constance (Bodensee), and Maggiore—straddle the French, German-Austrian, and Italian borders, respectively. The Rhine, navigable from Basel to the North Sea, is the principal inland waterway.
爱琴海上的火山明珠——圣托里尼岛
堆晶岩捕虏体主要组成矿物的电子探针数据主要由中国科学院地质与地球物理研究所电子探针室韩秀伶分析,所用仪器型号为法国产CAMEBEX SX51。测试条件:加速电压15kV,束流3.8nA。测试结果见表4-2至表4-7。1.橄榄石
橄榄石是尖晶石二辉橄榄岩、橄辉岩中的主要堆晶矿物,在辉石岩、橄长岩和部分辉长岩中以填隙矿物出现。所分析的橄榄石以富Fe、Mn,贫Ti、Ca为特征(表4-2),Fo值为71~84,主要为贵橄榄石。尖晶石二辉橄榄岩中的橄榄石Fo值较高(83~84),但明显低于一般地幔橄榄岩中橄榄石的Fo值(89~92),而与堆晶橄榄岩的橄榄石Fo值(张旗等,1992)相当,表示此类橄榄岩是岩浆分异作用早期的堆积体。骆驼场堆晶岩捕虏体中橄榄石更贫Mg,富Fe、Mn,显示了其岩浆演化程度较高的特征。橄榄石MnO含量为0.17%~0.78%,远高于中国东部新生代玄武岩中橄榄岩包体橄榄石的MnO含量。
表4-2 堆晶岩捕虏体中橄榄石的化学成分(wB/%)及分子组成(%)
注:W表示骆驼场,其他均为宁城-喀喇沁地区,以下各表同。
2.辉石
斜方辉石的化学成分及有关参数见表4-3,在辉石分类中分属顽火辉石、古铜辉石和紫苏辉石。其En含量为68~79,绝大多数大于78。由橄榄岩→辉石岩→苏长岩→辉长岩,斜方辉石的En含量明显降低,Fs则明显增高,显示了连续演化的特征,其总的演化趋势与南非Bushveld和东格陵兰Skergaard层状基性杂岩体中斜方辉石化学成分的演化规律相类似(图4-3),但本区的斜方辉石中含Wo量较2个杂岩体偏低。与喀喇沁地区堆晶岩相比,骆驼场堆晶岩捕虏体中斜方辉石更富Fe,贫Mg,与橄榄石成分一致,反映其岩浆演化程度较高。一般说来,斜方辉石中CaO含量较低,其含量和结晶温度有明显关系,即随温度升高而增加。本区堆晶岩捕虏体中斜方辉石CaO含量低于中国东部新生代橄榄岩包体中斜方辉石CaO(池际尚等,1996;鄂莫兰等,1987)含量,而与承德黑山斜长岩杂岩体中斜方辉石CaO含量(阎国翰等,1993)相当,反映二者形成的温度相似。
表4-3 宁城地区堆晶岩捕虏体中斜方辉石的化学成分(wB/%)及分子组成(%)
图4-3 堆晶岩捕虏体中辉石的Di-Hd-En-Fs图
空心圆圈为骆驼场堆晶岩中单斜辉石,实心圆为喀喇沁堆晶岩中辉石,方块为喀喇沁堆晶岩中斜方辉石;A为黑山杂岩体辉石成分演化趋势,B为Skergaard杂岩体辉石成分演化趋势,C为Bushveld辉石成分演化趋势(图中右下角小图为辉石分类图)
单斜辉石的化学成分及有关参数见表4-4。两个地区不同类型堆晶岩捕虏体中单斜辉石成分相差不大,为En58.2~42.7Wo50~41Fs10.6~0.6,在辉石分类图上均落入透辉石区(图4-3)。从超镁铁质岩石到镁铁质岩石,单斜辉石中En及Wo略有降低,Fs略有升高,但总体上均显示了高MgO(13.86%~16.82%)、低Na2O(0.15%~1.37%)的特点。
表4-4 堆晶岩中单斜辉石的化学成分(wB/%)及分子组成(%)
总的来看,堆晶岩捕虏体中辉石的化学成分演化与Bushveld和Skergaard两个杂岩体成分演化相似,后者的单斜辉石和斜方辉石的成分演化均反映了平衡条件下缓慢冷却结晶作用。堆晶岩捕虏体中的辉石和斜长石矿物均未发现明显的环带构造,也证明它们是平衡条件下缓慢冷却结晶的产物。
3.角闪石
角闪石镜下呈蓝绿色—棕色,有3种产状:①原生的自形—半自形晶体,分别以堆晶和后堆晶矿物出现;②交代成因的晶体,呈反应边结构包在辉石或橄榄石外围,有时又被金云母所包围;③呈片晶分布在单斜辉石上。角闪石的化学成分列于表4-5。宁城堆晶岩捕虏体中,除样品D4(角闪岩)中角闪石为普通角闪石外,其余主要为韭闪石质角闪石,其(Ca+Na)B>1.34,NaB<0.67,(Na+K)A=0.75~0.9,Ti=0~0.26,Si变化于6.17~6.38之间,据Mg′值可以分为含铁韭闪石(Mg′=44.5~44.9)和韭闪石(Mg′=74.4~80.4)两类,且同一个样品中,不同产状的角闪石成分相差不大。在角闪石的(Na+K)-Si图(Menzies等,1987)中均落入上地幔韭闪石范畴(图4-4)。和我国东部上地幔捕虏体中的韭闪石(樊祺诚等,1992)相比,显示了贫 Cr2O3(0~0.35%)、TiO2变化大(0~4.09%)的特点。依其成分和产状变化,与德国Eifel 下地壳堆晶成因镁铁质岩石捕虏体中的韭闪石极为相似(Loock et al.,1990)。
表4-5 堆晶岩捕虏体中角闪石化学成分(wB/%)
图4-4 堆晶岩中角闪石的Si-(Na+K)图
黑方块为浅闪石(据Menzies等,1987);实心圆为堆晶岩中角闪石
有关韭闪石的成因,多数学者,如樊祺诚等(1992)主张,不管其产状如何(填隙、嵌晶、巨晶或作为包裹体矿物),都直接或间接地与地幔流体的交代作用有关。因为韭闪石属硅不饱和矿物。但也有人认为,湿的地幔橄榄岩在1~3GPa部分熔融形成的液体是Si饱和的,这种液体不能形成类似于韭闪石的角闪石类矿物(沈步明等,1996)。目前提出的有关韭闪石在地幔中形成的模式有以下2种:①铬尖晶石+透辉石+流体→韭闪石;②石榴子石+透辉石+流体→韭闪石,韭闪石是亏损程度较低的地幔岩和含水流体之间交代作用的产物。Esperanca等(1988)在研究美国西部CampCreek下地壳镁铁质岩石捕虏体时,也发现有一套以韭闪石质角闪石为主要组成矿物的角闪石岩。他们认为在地壳中有一些区域的物理化学条件较为异常(低 ,高 ),更适于结晶韭闪石,而不是长石。在这些区域容易形成以缺Si、富集LREE为特点的角闪岩(韭闪石角闪岩,Mg′值常≤0.7),而在更高的压力和温度下,这一组合可以为Si 高的辉石岩取代,但其碱质和LREE将明显减少。在喀喇沁-宁城堆晶岩捕虏体中,有两个高Ti、低Si、高LREE含量的韭闪石角闪岩样品特征与Camp Creek地区下地壳角闪岩捕虏体特征相似,表明它们之间具有相似的成因,或形成于相似的环境。
骆驼场堆晶岩捕虏体中的角闪石为后堆晶矿物,薄片中以绿色为主,成分上为钙质角闪石中的普通角闪石。与宁城—喀喇沁地区大多数角闪石相比,具有高 Si,低 Al2O3(2.87%~5.05%),低Na2O、K2O的特点,而和样品D4中的角闪石成分相近。
图4-5 堆晶岩中角闪石的Al2O3-TiO2和Si-Al图解
(据姜常义等,1984)
姜常义等(1984)讨论了火成岩中钙质角闪石化学成分的变化,进而区分了幔源火成岩和壳源火成岩中钙质角闪石成分的差异,并以此进行了火成岩成因的研究。他们认为幔源角闪石含Al2O3>10%,Si/(Si+Al+Ti)<0.765;而壳源角闪石含Al2O3<10%,与岩浆的化学组成、结晶温度及压力条件无明显关系。从TiO2-Al2O3和Si-Al变异图中(图4-5)可以清楚地看出,喀喇沁-宁城堆晶岩捕虏体中绝大多数角闪石具有幔源角闪石成分特征,个别角闪石(如打鹿沟D4)和骆驼场堆晶岩捕虏体中角闪石相似,具有壳源角闪石的成分特征。角闪石成分上的间断及差异可以归因于两个因素,即岩浆成分和结晶条件,而岩浆成分上的差异又取决于岩浆源区的性质。因此,幔源和壳源钙质角闪石成分上的差异,并不是由于壳源和幔源岩浆生成条件的突变引起的,而应归因于岩浆成分和/或结晶条件的不同。野外的观察表明以普通角闪石为主要组成矿物的角闪岩(如样品D4)和含有韭闪石质角闪石填隙矿物的辉长岩有时成互层状产出,后文对全岩地球化学的分析也证明喀喇沁堆晶岩捕虏体来自于相同的岩浆源区,因此角闪石成分上的间断可能主要是由于岩浆房中局部结晶条件的差异引起的。
4.云母
除角闪岩和斜长岩外,云母在两个地区不同种类的堆晶岩捕虏体中均有分布,且含量不一,高者在个别辉石岩、橄榄岩中可达10%左右。镜下云母呈红褐色,有3种产状:①呈自形片状(3~8mm)与橄榄石、辉石矿物颗粒相互镶嵌,显示具有原生特点;②呈他形填隙,为后堆晶矿物;③以不规则鳞片状叠于辉石矿物上,或包在角闪石、辉石周围,显示交代成因。其代表性的化学成分列于表4-6。云母的Mg/Fe 比值比较高,为4.43~5.59,已属于金云母范畴,在云母的Mg/(TFe+Mg+Mn+Ti)-Mg/(TFe+Mg)图解中,也落入金云母区域(图4-6)。在云母的Mg-(AlⅥ+Fe3++Ti)(Fe2++Mn)图解中(Foster,1960),和金伯利岩中云母巨晶、金刚石后生云母包裹体及金伯利岩管中深源包体中的金云母成分比较接近(图4-7)。此外,这些云母具有较高的Al2O3(14.34%~15.44%)及较低的TiO2(1.81%~4.24%),与地幔橄榄岩中脉状产出的金云母(Wilkinson et al.,1987)类似,具有金伯利岩和碱性玄武岩中地幔捕虏体原生金云母贫FeO、TiO2(Boettcher et al.,1980)的特点。尤其值得注意的是骆驼场堆晶岩捕虏体中金云母含有很高的Cr2O3(1.31%~1.64%),完全可以和金伯利岩中金云母相比,可能表示其物质来源较深。
表4-6 堆晶岩捕虏体中金云母的化学成分(wB/%)
金云母的成因有以下3种:①产在幔源岩石中,常作为交代矿物,为典型地幔交代矿物之一,据Kushiro等(1967)的实验结果,在地幔橄榄岩中,金云母最少可以稳定于1300℃、4GPa条件下;②接触交代成因,为酸性侵入体与富镁贫硅的碳酸盐围岩接触交代反应的产物;③Villaseca等(1999)在下地壳的长英质麻粒岩捕虏体中发现一种特别富TiO2(4.99%~6.45%)和F(6%)、贫H2O的金云母,实验研究表明它是高温脱水熔融反应的残余。
堆晶岩中含有金云母(包括原生和次生)的现象还鲜有报道,显然原生金云母及堆晶成因金云母既排除了高温脱水熔融反应的可能性,又排除了接触交代成因,堆晶岩捕虏体中的金云母和韭闪石的存在虽然非常类似于“地幔显交代矿物组合”,但它是发生在下地壳的岩浆房中,推测它主要是受岩浆成分和结晶条件的控制。作为晶间矿物存在的云母可能是在堆晶岩的岩浆演化后期晶出的,而交代成因的云母则可能是堆晶岩受到了后期或稍晚来自地幔的富钾流体或熔体交代而形成的。

5.长石
不同地点、不同岩性的堆晶岩捕虏体中长石主要是斜长石,且其成分差别很大(表4-7)。就喀喇沁-宁城地区所发现的3处斜长岩捕虏体而言,作为堆晶矿物的斜长石比作为后堆晶矿物的斜长石基性程度高,前者主要为中、拉长石(An=33.18~56.73,;Or=0.58~0.71,Ab=42.68~66.20),后者为更长石(An=18.86,Or=0.92,Ab=80.22)。另外在个别斜长岩的晶间矿物中还出现了碱性长石(表4-7)。随着碱性长石含量的增加,暗色矿物含量相应减少,反映了斜长岩从基性到偏碱性的演化过程。本区斜长岩中斜长石的An总体上低于太古宙斜长岩和元古宙地块型(massif-type)斜长岩中的斜长石,而和层状侵入体的斜长岩中斜长石An值(Ashaw,1993)相当。橄长岩和苏长岩中的斜长石为拉长石(An=55.5~56.42,Or=0.39~1.91,Ab=42.59~43.19),而辉石岩中的斜长石成分变化较大(An=59~35.8)。
表4-7 堆晶岩中长石的化学成分(wB/%)及分子组成(%)
注:B18-2为碱性长石。
6.副矿物
钛铁矿、磁铁矿、黄铜矿、磷灰石是堆晶岩捕虏体中最普遍的副矿物。另外,在超镁铁质岩中有少量尖晶石,呈他形,充填于橄榄石、辉石粒间。个别角闪石中偶尔可见褐帘石(Dy8),暗色辉长岩中可以见到单斜辉石上具有金红石的出溶体。随着岩石基性程度的降低,岩石中锆含量有明显增加的趋势。

而这个地方就是
圣托里尼岛(Santorini)。
费拉(Fira)的日落
圣托里尼岛(Santorini),古名为希拉(Thera),官方名为锡拉岛(Thira)。圣托里尼是在13世纪由拉丁帝国命名的,参考了圣·爱莲(Saint Irene)这一名字,来自于古老的教堂的名字。圣托里尼(Santorini)的名字是圣·爱莲(Santa Irini)的缩写。
圣托里尼岛是在希腊大陆东南约200公里的爱琴海上的岛。它是基克拉迪群岛最南端的岛屿,面积约73平方公里(28平方英里),2011年人口普查人口为15550人。

圣托里尼岛火山口
这个岛是有记载的 历史 上最大的火山爆发之一:米诺斯(Minoan)火山爆发(有时被称为锡拉Thera火山爆发),发生在大约3600年前米诺斯文明的鼎盛时期。火山爆发留下一个巨大的破火山口,周围有几百米深的火山灰沉积。它可能通过一场巨大的海啸间接导致了克里特岛(Crete)上的米诺斯文明的衰败。另一个流行的理论认为这场火山爆发是亚特兰蒂斯(Atlantis)传说的源头。
火山口的航空照片
它是爱琴海南部火山弧中最活跃的火山中心,尽管今天遗留下来的主要是一个积满水的火山口。火山弧长约500公里,宽约20至40公里。该地区最早形成火山活动是在大约300万至400万年前,而圣托里尼的火山活动始于大约200万年前,当时从阿科多提利(Akrotiri)附近的火山口喷出英安质的熔岩。

圣托里尼岛的地质概况
圣托里尼岛是基克拉迪群岛最南端的岛屿,基克拉迪群岛(Cyclades)是一个被称为基克拉迪地块(Cycladic Massif)的变质杂岩的一部分。该变质杂岩形成于中新世(23-5百万年),在6000万年前的阿尔卑斯造山运动中发生褶皱和变质。
圣托里尼岛坐落在一个小的、非火山的基底上,代表了以前的非火山岛,大约9 6公里。基底岩石主要由变质灰岩和片岩组成,形成于阿尔卑斯造山期。变质级别为蓝片岩相,是非洲板块在欧亚板块下俯冲而形成的构造变形。渐新世(33-23百万年)与中新世(23-5百万年)之间发生俯冲,变质程度代表基克拉迪蓝片岩带的最南端的程度。
圣托里尼岛火山活动的原因
圣托里尼岛的火山活动是由于克里特岛(Crete)西南的希腊海沟俯冲带造成的。非洲板块北缘的海洋地壳正俯冲到希腊和爱琴海之下,爱琴海是变薄的大陆地壳。俯冲迫使希腊弧的形成,包括圣托里尼和其他火山中心,如玛塔纳(Methana)、米洛斯(Milos)和科斯(Kos)。
圣托里尼岛独特的火山地貌
圣托里尼岛上可以看到是盾状火山建造和火山口崩塌的重复序列。火山口周围的内海岸最高处是300多米的陡峭悬崖,呈现出层层叠叠凝固的熔岩,主要城镇坐落在顶部。
然后地面向外倾斜,向下延伸至外围,外围的海滩平滑而浅的。沙滩颜色取决于暴露的地层,沙子或卵石由各种颜色的凝固后的熔岩组成,如红海滩、黑海滩和白海滩。
红海滩
圣托里尼岛火山喷发情况
圣托里尼火山曾多次喷发,喷发程度各不相同。至少有12次大规模的火山爆发,其中至少有4次形成火山口。最著名的喷发是米诺斯火山喷发(Minoan eruption)。喷发产物从玄武岩一直到流纹岩,流纹岩产物与最具爆炸性的喷发程度有关。
最早的火山爆发发生在阿科多提利半岛(Akrotiri Peninsula),其中许多是海底火山,活跃于65万至55万年前。它们在地球化学上与后来的火山活动不同,因为它们含有角闪石。
在过去的36万年中,有两个主要的循环周期,每一个周期都以两次火山口的形成标志火山喷发结束。当岩浆演化成流纹岩成分时,这种循环就结束了,导致了最具爆炸性的喷发。同时在大周期之间有一系列的子周期。

Minoan eruption米诺斯火山爆发
毁灭性的锡拉(Thera)火山爆发是爱琴地区在特洛伊陷落之前发生的最重要的 历史 事件。这可能是最近几千年来地球上最大的火山爆发之一。
在圣托里尼岛,人们发现从火山喷发中抛出的白色火山碎屑沉积物厚达60米,覆盖着火山喷发前标记地面的土壤,形成了被三个相当明显分带的层,表明火山喷发的不同阶段。2006年,一个由国际科学家组成的研究小组的考古发现显示,圣托里尼岛事件的规模远比之前认为的要大,约61立方公里的岩浆和岩石进入大气,产生的火山碎屑物估计有100立方公里。
而在过去的5000年里向大气中释放了大量物质的事件,只有1815年的坦博拉(Mount Tambora)火山喷发,公元181年的陶波湖(Lake Taupo)喷发,以及公元969年的长白山喷发(Changbai Mountain)。

米诺斯火山之后的火山爆发
米诺斯火山爆发后的活动主要集中在环礁湖中心的卡梅尼群岛(Kameni islands)。它们是米诺斯火山爆发以后形成的,第一次喷发发生在公元前197年。从那时起, 历史 记录上记录了9次地面火山喷发,最近一次结束于1950年。1707年,一座海底火山冲破了海面,形成了现在位于环礁湖中心的新卡梅尼火山(Nea Kameni)的活动中心,而以它为中心的火山喷发还在继续。20世纪发生了三次,最近一次是在1950年。

阿科罗提利文明遗址
从1967年开始,Spyridon Marinatos教授开展对阿科多提利(Akrotiri)遗址的挖掘工作,使圣托里岛成为克里特岛(Crete)以外最著名的米诺斯文明(Minoan)遗址。
一个城镇被发现,它揭示了多层建筑、街道和广场的综合体,以及高达8米的墙壁遗迹,所有这些都埋在火山喷发留下的火山灰中。
在阿科多提利发现的著名考古遗迹是壁画,由于它们被保存在数米深的火山灰下,所以保持了原有的颜色。
这个小镇的排水系统也非常发达,先进的排水系统和三层建筑等似乎遥遥领先于那个时代理应具备的技术,他们甚至还建造有两层楼的水管设施。
双管道系统、先进的建筑和阿科多提利遗址的外观布局,这些都与柏拉图在《对话录》中描绘的亚特兰蒂斯极为相似,有人猜测克里特岛上的米诺斯文明是目前为止对亚特兰蒂斯可信度最高的猜想。
壁画
不同于庞贝古城,当时火山喷发猝不及防,人们生活的场景也被火山灰凝固在那一刻。阿科罗提利文明遗址内,当时的人们似乎有警觉,居民及时撤走,似乎在火山爆发前还发生了地震,火山不但摧毁了圣托里尼岛,而且引发了大海啸,巨浪重创70公里外的克里特岛。
壁画
米诺斯文明一蹶不振,繁华不再。阿科罗提利文明就这样被埋在60多米深的火山灰底下。直到1967年才被挖出来,精美的壁画搬进了博物馆——费拉史前博物馆。
