Earth's magnetic field is generated by fluid motions in the outer core. This geodynamo has
operated for over 3.4 billion years. However, the mechanism that has sustained the …

Reconstructing Earth history during the Hadean defies the traditional rock-based approach
in geology. Given the extremely limited locality of Hadean zircons, some indirect approach …

The population of planets smaller than approximately 1.7 Earth radii (R⊕) is widely
interpreted as consisting of rocky worlds, generally referred to as super-Earths. This picture …

Many geological and geochemical changes are recorded on Earth between 3 and 2 Ga.
Among the more important of these are the following:(1) increasing proportion of basalts with …

The current state and surface conditions of the Earth and its twin planet Venus are drastically
different. Whether these differences are directly inherited from the earliest stages of …

在调研国内外众多金属矿山和收集大量相关文献的基础上, 综述了国内外金属矿山开采现状及
研究进展, 聚焦深部开采主要工程技术难题, 从开采动力灾害预测防控, 深井高温热害控制治理 …

In addition to long-lived radioactive nuclei like U and Th isotopes, which have been used to
measure the age of theGalaxy, also radioactive nuclei with half-lives between 0.1 and 100 …

Massive steam and CO 2 atmospheres have been proposed for magma ocean outgassing of
Earth and terrestrial planets. Yet formation of such atmospheres depends on volatile …

Mineral resources provide an importantmaterial basis for a country's economic and social
development. After decades of large-scalemining, the shallow-metalmineral resources of …

Accurate knowledge of the mineralogy is essential for understanding the lower mantle,
which represents more than half of Earth's volume. CaSiO3 perovskite is believed to be the …
