The internal structure of Venus and Earth evolved with a different pace, despite the fact that the planet likely formed under the same conditions, says us planetary scientist Joseph G. O’rourke (Joseph G. O’rourke). He proposed a model, according to Read more
Carbon in the Earth’s core is two times less than previously believed — such data obtained in Geophysics using the model of formation of the Earth from carbonaceous chondrites. To do this, they analyzed the distribution of carbon between metal Read more
Modeling has shown that during previous geological eras in the mantle, part of which was still liquid, intensive convective flows. In conjunction with previous studies, indicating the high conductivity of silicate melts at high pressure, this suggests that the ancient Read more
Italian researchers have created a theoretical model of volcanism in the area North-East of China and the Japanese trench. According to the calculations, the volcanoes emerged as a result of loss of water by the edge of the Pacific lithospheric Read more
Geophysicists have developed a simple and not resource-intensive software tool that allows you to identify the gravitational waves, caused by earthquakes. Since gravitational waves travel at the speed of light, the new method will help to detect earthquakes much earlier Read more
On American lake Mi noticed a rare phenomenon — “ice volcanoes”. Such structures are formed with a suitable combination of weather conditions when moving under the icy crust waves make their way through the cracks. “Ice volcanoes” have nothing to Read more
Scientists have modeled the chemical composition was found in the limestone age of 2.7 billion years micrometeorites. The obtained results indicate very high (more than 70 percent by volume) carbon dioxide content in the atmosphere of the time. Gas shell Read more
Geologists found the oldest impact crater on Earth — they became the structure Yarrabubba located in Australia. It turned out that the age of the shock structure is 2229 million years, more than 200 million years of age more of Read more
Scientists have confirmed the existence of a powerful magnetic field of the Earth has 4.2 billion years ago, in the oldest geological era — Katara. This became known thanks to a detailed study of ancient inclusions of zircon crystals, discovered Read more
The researchers presented a series of measurements indicating that the largest meteorite in last million years has fallen on the territory of modern Laos. Geological traces of this impact covers about one-tenth of the Land area, but the crater from Read more
