We are interfering with major geological forces.(我們受到主要地質(zhì)力量的干預。)

The other islands, which emerged via geological processes such as volcanism, possessed no terrestrial life.(其他島嶼是通過如火山作用的地質(zhì)作用形成的，沒有陸地生命。)

Hills and mountains are often regarded as the epitome of permanence, successfully resisting the destructive forces of nature, but in fact they tend to be relatively short-lived in geological terms.(丘陵和山脈通常被認為是永恒的象征，成功抵御著自然的破壞力量，但其實它們從地質(zhì)學角度講往往是相對短暫的。)

Certain features of these engravings lead to the conclusion that they are of great age—geological changes had clearly happened after the designs had been made.(這些雕刻的某些特征讓人得出它們年代久遠的結論——這些設計完成之后顯然有地質(zhì)變化發(fā)生。)

In 1831 when Smith was finally recognized by the Geological Society of London as the "father of English geology", it was not only for his maps but also for something even more important.(1831年，史密斯最終被倫敦地質(zhì)學會認可為“英國地質(zhì)學之父”，這不僅是因為他的地圖，而且是為了其他更重要的原因。)

While there are a dozen or more mass extinctions in the geological record, the Cretaceous mass extinction has always intrigued paleontologists because it marks the end of the age of the dinosaurs.(雖然在地質(zhì)記錄中有十幾次甚至更多的大滅絕，但白堊紀的大滅絕總是引起古生物學家的興趣，因為它標志著恐龍時代的結束。)

Bown and his colleagues stumbled across it while they were doing geological mapping in the region.(鮑恩和他的同事在該地區(qū)進行地質(zhì)測繪時偶然發(fā)現(xiàn)了它。)

Charles Lyell made a good estimate of the Tertiary Period from the fossil record, but his method could not be extended to earlier geological periods.(查爾斯·萊爾根據(jù)化石記錄對第三紀作出了很好的估計，但他的方法不能擴展到更早的地質(zhì)時期。)

That's a baby in geological terms.(但從地質(zhì)年代上來說，它還是一個嬰兒。)

The overall result has been to make entrance to professional geological journals harder for amateurs, a result that has been reinforced by the widespread introduction of refereeing.(這樣做的總體結果就是業(yè)余愛好者想在專業(yè)地質(zhì)學期刊上發(fā)表文章就更難了，而評審制度的廣泛采用又進一步加強了這一結果。)
