Located roughly 3,000 kilometers down, this zone sits just above the boundary between the planet\u2019s molten outer core and its solid mantle. Unlike a perfect sphere, the D layer is surprisingly patchy. Its thickness varies greatly from place to place, with some regions even lacking a D layer altogether \u2013 much like continents rise above the Earth\u2019s oceans. These intriguing variations have captured the attention of geophysicists, who describe the D layer as a heterogeneous, or non-uniform, region.<\/p>\n<p>A new study led by Dr. Qingyang Hu (Center for High Pressure Science and Technology Advanced Research) and Dr. Jie Deng (Princeton University) suggests the D layer might be originated from Earth\u2019s earliest days. Their theory hinges on the Giant Impact hypothesis, which proposes a Mars-sized object slammed into the proto-Earth, creating a planet-wide magma ocean in the aftermath. They believe the D layer may be a unique composition leftover from this colossal impact, potentially holding clues to Earth\u2019s formation.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>New research suggests the mysterious D layer at Earth\u2019s core-mantle boundary might have formed from remnants of an early colossal impact, with iron-rich peroxide playing a key role in its unique and enduring features.
