Australia has recently become the center of two groundbreaking geological discoveries that shed light on Earth's violent history.
澳洲近期成為兩項開創性地質發現的中心，揭示了地球劇烈的歷史。
In June 2026, scientists from Curtin University confirmed that the North Pole Dome in Western Australia is the world’s oldest impact crater.
2026年6月，科廷大學的科學家證實，位於西澳州的北極穹丘是世界上最古老的撞擊坑。
Researchers confirmed its status by analyzing shock-affected zircon and apatite crystals, as well as distinct shatter cones, proving that major space collisions were shaping our planet long ago.
研究人員通過分析受衝擊的鋯石和磷灰石晶體，以及獨特的碎裂錐，證明在久遠的過去，重大的太空撞擊曾形塑著我們的行星。
The Deniliquin structure is a massive, proposed impact site estimated at 520 kilometers in diameter.
丹尼利昆結構是一處規模龐大、直徑估計達520公里的潛在撞擊點。
While it remains unconfirmed, geophysical data suggests it could be the largest impact structure on Earth, possibly linked to an ancient mass extinction.
儘管目前尚未經過實地確認，但地球物理數據表明，這可能是地球上最大的撞擊結構，並且可能與某場古老的大規模滅絕事件有關。
Together, these sites demonstrate how Australia’s landscape holds the secrets to the cataclysmic events that have influenced our planet's evolution over billions of years.
這些地點共同顯示了澳洲的地貌如何保存著影響地球數十億年演化的災難性事件之秘密。
