Scientists Link Giant's Causeway Formation to Globally Significant Volcanic Event

科学家将巨人堤道的形成与全球性重大火山事件联系起来

For centuries, Irish folklore has attributed the creation of the Giant's Causeway to the legendary giant Finn McCool, who supposedly hurled enormous rocks into the sea to confront his Scottish rival, Benandonner.

几个世纪以来，爱尔兰民间传说一直将巨人堤道的创造归功于传奇巨人芬恩·麦克库尔，据说他将巨石扔进海里，以对抗他的苏格兰对手贝南多纳。

However, a team of geochronologists has now revealed that the iconic formation owes its existence not to mythical conflict but to an extraordinarily intense volcanic event approximately sixty million years ago.

然而，一个地球年代学家团队现在已经揭示，这个标志性的地质构造并非归因于神话中的冲突，而是归因于大约六千万年前一场异常强烈的火山事件。

Researchers from the British Geological Survey and the Geological Survey of Northern Ireland have determined that volcanic activity in the Antrim region produced the Causeway's forty thousand distinctive interlocking basalt columns over a span of merely 5.5 million years.

来自英国地质调查局和北爱尔兰地质调查局的研究人员已确定，安特里姆地区的火山活动在仅仅五百五十万年的时间跨度内，形成了巨人堤道四万根独特且相互交织的玄武岩柱。

This revised geological timescale is eight million years shorter than previous estimates had suggested, fundamentally altering scientists' understanding of how rapidly these formations emerged.

这个修正后的地质时间尺度比先前的估计缩短了八百万年，从根本上改变了科学家对这些地貌如何迅速形成的理解。

The findings carry broader implications for understanding plate tectonics in the North Atlantic.

这些发现对理解北大西洋的板块构造具有更广泛的启示。

Doctor Simon Tapster, a geochronologist at the British Geological Survey, emphasized that researchers can now correlate the timing of the Causeway's formation with other volcanic systems across the region at an unprecedented level of precision.

英国地质调查局的地质年代学家西蒙·塔普斯特博士强调，研究人员现在能够以史无前例的精确度，将巨人堤道的形成时间与该地区的其他火山系统联系起来。

He noted that prior to this volcanic event, Greenland had been physically joined to the crust beneath northern Britain.

他指出，在这次火山事件之前，格陵兰曾与不列颠北部下方地壳物理性地相连。

Perhaps most remarkably, the research demonstrates that by the conclusion of this volcanic episode, the North Atlantic Ocean had begun to open between Greenland and the British Isles.

也许最引人注目的是，该研究表明，在此次火山活动期结束时，北大西洋已开始在格陵兰和不列颠群岛之间裂开。

Were it not for this cataclysmic geological upheaval, the familiar geography of the North Atlantic would look profoundly different today.

若非这场灾难性的地质剧变，北大西洋如今熟悉的地理面貌看起来将会大不相同。

For the first time, scientists have been able to definitively connect the earliest lava flows in the region to a major globally impacting volcanic event recorded in rocks as distant as Greenland.

科学家首次得以将该地区最早的熔岩流，与记录在远至格陵兰的岩石中、具全球性影响的重大火山事件明确地联系起来。
