科罗拉多州派克斯峰的岩石 揭示了地球古代"雪球地球"阶段的线索 Rocks on Colorado's Pikes Peak reveal clues about Earth's ancient "Snowball Earth" phase.

在科罗拉多的派克斯峰发现的不寻常的岩石 提供了地球“雪球地球”阶段的线索 那时地球在七亿多年前 完全被冰覆盖 Unusual rocks found on Colorado's Pikes Peak offer clues about Earth's "Snowball Earth" phase, when the planet was entirely covered in ice over 700 million years ago. 研究人员利用辐射测算日期确定这些在巨大的冰压下形成的微薄的砂岩是来自地球的雪球时期。 Researchers used radiometric dating to determine that these pebbly sandstones, formed under immense ice pressure, are from the Snowball Earth period. 这一发现使我们深入了解了这个冰冷时代的地质过程和条件,有助于我们理解地球历史和早期生命的演变。 This discovery provides insight into the geological processes and conditions during this icy era, contributing to our understanding of Earth's history and the evolution of early life.
