Paleoclimate the climate conditions of geologic periods in the ancient past.(Paleoclimate-古氣候指的是古代地質時期的氣候條件。)

As geologists, we examine layers of sediment on the Earth' s surface to approximate the dates of past geologic time periods.(作為地質學家，我們研究地球表面的沉積層以估算過去地質時期的年代。)

A 2008 study described the complex geologic history of Oslofjorden.(2008年，一項研究從地質學上揭示了奧斯陸峽灣錯綜復雜的過去。)

Recent geologic evidence indicates that contrary to what had been believed, substantial areas along the coast were free of ice as early as 16,000 years ago.(最近的地質證據表明，早在16,000年前，沿海岸的大部分地區就沒有冰了，這與人們過去的看法相反。)

The drift of the last glaciation was deposited during one of the most recent epochs of geologic time, the Pleistocene, which lasted from 1.8 million to 10,000 years ago.(最后一次冰川作用的漂浮物沉積在最近的其中一個地質時期——更新世，這段時期從180萬年前持續到1萬年前。)

More than 20,000 apartments in France are now heated by warm underground water drawn from a heat reservoir in a geologic structure near Paris called the Paris Basin.(目前在法國，有超過2萬套的公寓是由溫暖的地下水供暖的，這些地下水來自一個叫做巴黎盆地的地質構造的熱儲，位于巴黎附近。)

Lyell's strategy for estimation of geologic dates was not very accurate.(萊爾估算地質年代的方法不是很準確。)

The duration of previous geologic periods was difficult to determine.(以前很難確定地質期的持續時間。)

As he explains, the Geologic Time Scale is largely based on the stratigraphic record.(他解釋說，地質時間尺度很大程度上基于對地層的記錄。)

Geologic evidence shows that southern African has been slowly rising for the past 100 million years, yet it has not experienced a tectonic collision for nearly 400 million years.(地質證據顯示，非洲南部的板塊在過去的1億年里一直在緩慢地上升，然而它在近4億年里沒有經歷過一次構造碰撞。)
