科学家在地球地壳中发现了两个古老的“岛屿”, 对地质过程提出了挑战性的看法。 Scientists discover two large, ancient "islands" in Earth's mantle, challenging views on geological processes.

乌得勒支大学的一项新研究在《自然》杂志上发表,在地球地壳中发现两个大而古老的“岛屿”,这些岛屿比周围地区更热、更僵硬。 A new study from Utrecht University, published in Nature, has found two large, ancient "islands" in Earth's mantle that are much hotter and more rigid than surrounding areas. 这些「大型低地震速率省」(LLSVPs)质疑混杂且快速流动的地壳的想法, These "Large Low Seismic Velocity Provinces" (LLSVPs) challenge the idea of a well-mixed and fast-flowing mantle, suggesting it may be less active than previously thought. 这一发现可能会改变我们对火山和山岳形成等地质过程的理解。 The discovery could change our understanding of geological processes like volcanism and mountain formation.
