UDC (523.3.-4/.5:551.12):553.2 THE HOT EARTH MODEL. A NEW APPROACH TO MINERAL DEPOSITS PHYSICS
The paper discusses the physics of phenomena occurring on the hot expanding and pulsating Earth at the early development stage. The initial temperature of the Earth’s matter was ≈ 30 000°K at a density of ≈ 30 g/cm3, and the matter itself was in the gaseous state. During the Earth’s evolution the matter chilled, condensed, forming the outer core, and crystallized, accreting mantle at the outer core boundary. At the initial stage of the Earth’s evolution the temperature of its surface decreased (from 30 000°С) to the values below the critical point of metals (6625°С for gold). Metals under the critical temperature were subjected to s. c. “giant density fluctuations”, which enabled different metals (each under the respective temperature) to “merge” in giant “drops” that were prototypes of mineral deposits.
Key words: hot Earth model, mineral deposits physics. |
