Only 10% of the 150 or so known impact craters on Earth date from the early Precambrian Era, a time period covering some 88% of the Earth's history. Yet this Era encompasses fundamental events in the origin and evolution of our planet from the origin of life itself to the development of...

Phosphorus (P) is critical to modern biochemical functions and can control ecosystem growth. It was presumably important as a reagent in prebiotic chemistry. However, on the early Earth, P sources may have consisted primarily of poorly soluble calcium ph

~3.95–3.85 Ga-old Late Heavy Bombardment in the Earth-Moon system was succeeded by intermittent large impacts by asteroids of >10 km-diameter, represented by well-preserved multiple impact ejecta units in the oldest well-preserved supracrustal greenstone sequences in South Africa and Western ...
The formation of a protolunar disc by a giant impact with the early Earth is discussed, focusing on two classes of impacts: (i) canonical impacts, in which a Mars-sized impactor produces a planet-disc system whose angular momentum is comparable to that in the current Earth and Moon, and ...

However, the single impact scenario failed to explain why the makeup of the moon are near identical to the Earth, rather than a mix of Earth and another planet. In a successful giant-impact scenario, either most of the material that forms the moon comes from the Earth, or the impactor'...
Meteoroids, Meteors, and the Near-Earth Object Impact Hazard In considering the modern-day hazard from infalling near-Earth asteroids and comets, the focus has shifted toward the smallest, most frequent impacts that ... CR Chapman - 《Earth Moon & Planets》 被引量: 15发表: 2008年 The aste...
