火山

Plumes appeared over the Martian northern hemisphere regions such as east of Arabia Terra, the Nili Fossae region, and the south-east quadrant of Syrtis Major, an ancient volcano about 745 miles across.

股流在火星的北半球若干地带被发现，如，Arabia Terra东部，Nili Fossae 地区，Syrtis Major东南四分之一，一个大约745英里宽的古火山地区。

And now, up here on the edge of this collapsed volcano, I realize the ridge I've been hiking has taken me to the top of the rim shared by Tagus and the wholly intact bowl of an adjacent caldera, one that sprawls out for a few hundred meters inland.

现在，面对着坍塌的火山边缘，我意识到自己从山脊爬到山顶，而这山顶不单构成了塔霍河河口，同时也是另外一个完整的火山口的边缘，这个火山口继续向内陆蜿蜒几百米。

They lie in a straight line. Volcanoes on Mars are ten to a hundred times larger than those on Earth.

火星上的火山比地球上的要大十到一百倍，科学家以往曾对此十分迷惑。

Volcanic rocks of Xishanbulake Formation and Shuiquan Formation are of alkali basalt series, those of Zhamoketi Formation are of alkali basalt series and tholeiite series, and those of Beiyixi Formation are obviously characterized by bimodal assemblage and mostly belong to alkali volcanic rocks.

其中，西山布拉克组和水泉组火山岩均碱性玄武岩系列；扎摩克提组火山岩分属碱性火山武岩系列和拉斑玄武岩系列；贝义西组火山岩具有明显的双峰式组合特徵，大部分属碱性火山岩。

The basalt is belong island arc tholeiite and series of the calc-alkaline,and have character of island arc in rare earth element and trace element.

玄武岩属岛弧拉斑玄武岩和钙碱性系列，属太平洋型钠质类型，稀土、微量元素显示具岛弧特征，大地构造位置为岛弧中心靠近大洋一侧，与南侧那拉提晚泥盆—早石炭世侵入岩共同组成火山弧，同为古亚洲洋向北俯冲的产物。

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。

Still, if Toba erupted today like it did in the past, the results would be catastrophic.

但是，如果现在多巴火山像过去一样喷发，后果将是灾难性的。

One possibility occurred 70,000 years ago, when the Toba super-volcano erupted in Indonesia and triggered a nuclear winter that fewer than 15,000 individuals survived.

时间可能是在7万年前，当时印度的多巴超级火山喷发，引发了核冬天1，只有不到1.5万人活了下来。
