The consequences of the impacts of cosmic bodies on the Earth's surface are analyzed. The conditions of large craters formation on the solid surface of the planet are calculated using the recently introduced technique. The alpha-beta parametric plane is used to determine the bounds for the areas...
Ceres’ depleted large crater population is also at odds with that of Vesta, despite their similar collisional environment14. Vesta exhibits a significant number of larger craters (≥150 km; ref.8), including two basins >400 km (Fig. 1a). Topographic evolution models based on an ice-ric...
The rayed crater Zunil and interpretations of small impact craters on Mars A 10-km diameter crater named Zunil in the Cerberus Plains of Mars created 10 7 secondary craters 10 to 200 m in diameter. Many of these secondary craters... AS Mcewen,BS Preblich,EP Turtle,... - 《Icarus》 被...
Data from Operation IceBridge also revealed a negative gravity anomaly over the area, which is characteristic of impact craters.
To find out, scientists went to one of the few massive craters on Earth not erased by plate tectonics: the Sudbury crater in Canada."Sudbury is a 1.85-billion-year-old impact structure."Teresa Ubide, a geochemist at the University of Queensland in Australia."Sudbury was generated when a ...
Impacts of large meteorites or comets into Proterozoic continental crust may have opened basins as much as hundreds of kilometers in diameter. We suggest that basalt magma generated through pressure-relief, partial melting flooded the craters to form lava lakes, which evolved into lopoliths capped ...
They are often found on the Earth along tectonically active mountain-front desert settings where strong relief contrasts and the infrequent precipitation and runoff have prevented the formation of through-flowing drainage systems. When water is available to these drainage basins, it commonly arrives in...
It is apparent that remote sensing is not a panacea for the discovery and validation of new impact craters, but it can contribute by serving as a pathfinder both for the identification of promising structures and the possible locations of key deposits for detailed fieldwork and sampling....
Mount Fraser is a large scoria cone complex with two craters. The diameter of the base averages 1200 m and the highest point on the rim rises 125 m above the basalt plain immediately east of the Hume Freeway. It is a relatively simple volcanic structure with no tuff ring or parasitic co...
Further, an examination was performed of the magnitudes of earthquakes versus the distances from the craters for seven volcanoes, near which large earthquakes (M≥ 6) occurred during the past 30 years. All of the large earthquakes were found to have occurred at distances of approximately 10 km ...
