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 ...

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 phosphates, which may have rendered phosphate as...

~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 ...
In ad- dition, catastrophic seismic events in the densely populated, agricultural areas of China, in- cluding the 1303 surface wave magnitude (Ms) 8.0 Hongtong earthquake, the 1556 Ms 8.25 Huaxian earthquake and the 1920 Ms 8.5 Haiyuan earthquake, caused more than 200,000 casualties and ...
The authors assess the risk of overshoot beyond 1.5 °C warming, using three scenarios with minimal overshoot, brief overshoot and sustained overshoot. They show a risk of long-term Amazon dieback, which begins as early as 1.3 °C warming but is largely mitigated by reducing temperature ...
