1·If mineral veins sometimes resemble botanical illustrations, blame it on Earth's molten nature and fluid mechanics: when seen from above, a branching river also looks like a tree.
矿脉其实有时会像植物图鉴，是因为地球的熔融性质和流体力学机制：当我们俯视的时候，就能看到像树枝一样的分支河流。
2·Abandoned veins in mineral-rich countries have become viable again-and despite the relatively steep extraction costs, a miniature gold rush might be under way in Britain, too.
矿藏丰富的国家那些已被放弃的矿脉又重新开工——尽管开采成本比较高，英国的微型淘金热也可能正在进行中。
3·The types of veins increase, the mineral components get more complicated and higher temperature hydrothermal minerals evolve as the anthracite metamorphic ranks, whenever they are, get higher.
无论什么时代的无烟煤，随着其变质程度升高，煤中脉体种类增多，矿物成分变得复杂，较高温热水矿物出现。
4·The distribution of mineral nutrient elements was different in different leaf position, main leaf veins and soft leaves.
各种矿质元素在不同叶位以及同叶位的中肋和软叶中的分配均有所不同。
5·The types of veins increase, the mineral components get more complicated and higher temperature hydrothermal minerals evolve as the anthracite metamorphic ranks, whenever they are,...
