岩石

Petrological and geochemical characteristics of alkali-rich porphyries suggest that magmas might not be generated from subducted oceanic slab, but likely from the base of thickened crust, corresponding to eclogite-facies.

富碱斑岩产出的地质背景及岩石学和地球化学特征表明，富碱斑岩并非起源于俯冲的大洋板片，而是源于加厚地壳的底部，源区为榴辉岩相岩石。

According to this scheme, the Longmaxi Formation is only referred to as the black siliceous and carbonaceous shales at the base of the Silurian strata. All the carbonate rocks above it have been redelineated and redivided into new lithostratigraphic units.

新方案除对志留系底的黑色硅质碳质页岩沿用龙马溪组这一岩石地层单位名称外，其上的碳酸盐岩均重新划分和建立了新的岩石地层单位，并确定其涵义和时限标准。

Rock, sand and gravel: These surfaces are highly durable and can tolerate repeated trampling and scuffing.

岩石，沙子和碎石路：这些地表有高度的耐久力，能忍受重复的践踏和擦磨（然而，生长在岩石的青苔却很脆弱经不起重复的擦磨

Their vicious blade scythes and climbing claws are so sharp they can even cut through sheer rock, enabling the rock flayers to climb the most difficult overhangs with ease.

它们的镰爪和攀援爪都异常锋利，足以切割岩石，靠着锋利的爪子在各种岩石表面上快速爬行更时小菜一碟。

These rocks, and others throughout the equatorial region, are rich in sulfates, a telltale sign of water-lain sediments.

这些岩石与散布在整个赤道地区的其他岩石，都含有大量的硫酸盐，这是水底沉积的迹象。

The study of rock boreability for TBM tunnelling is one of the most important parts in engineering geology research.

在TBM施工前，岩石的可掘进性研究是隧道工程地质研究中的一项重要内容，而我国目前还没有进行岩石可掘进性研究的试验室。

When it was time for me to sail back to Cornwall, you came out and stood on a narrow rock, and we watched each other so far that only we two knew what was rock or boat or human.

当我不得不启程回康沃尔德时，你走了出来，站在一块窄窄的岩石上，我们远远地望着对方，远到只有我们才知道哪里是岩石哪里是船哪里是人。

When it was time for me to sail back to Cornwall, you came out and stood on a narrow rock, and we watched each other so far that only we two knew what was rock or boat or human.

在起锚返回康沃尔时，你出来了，站在一块窄窄的岩石上，我们望着彼此，渐行渐远，远到只有我们才能分辨哪里是岩石哪里是船哪里是人。

The other is a pair of rocky islets, black-tailed gulls wheeling around the crags.

要么是一对岩石岛礁，黑尾巴海鸥围着陡峭的岩石盘旋。有些办公室甚至这两幅画都挂了。

Secondly, study on bleaching of sandstone based on field characteristics, petrography, geochemistry and compared with other sandstone related, combined with geological setting of gas seepage in the area, reveals that natural gas leakage is responsible for bleaching of the sandstone on top of Yan\'an formation. The bleaching resulted from interaction between the reductive fluid and the rock. At the same time the bleaching suggests that the northeast of basin has experienced large scale gas seepage.

在此基础上，通过漂白砂岩野外露头地质特征、岩石学、地球化学以及相关砂岩的对比研究，结合研究区天然气逸散的地质背景，揭示砂岩漂白现象为上古生界天然气逸散过程中，还原性流体与岩石作用的结果，同时也表明其指示了天然气的大规模逸散作用。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
