- Аннотация: The primordially hydridic Earth (PHE) concept offers a transformative view of Earth’s formation, proposing a hydrogen-rich planetary composition with metal hydrides as a key component of the core. This chapter examines the chemical, physical, and geophysical implications of the PHE model, integrating laboratory experiments, field observations, and theoretical calculations. The model suggests that hydrogen, initially abundant in Earth’s interior, played a crucial role in the planet’s evolution. It explains phenomena such as the core’s density deficit, mantle dynamics, and the formation of geospheres through hydrogen degassing from metal hydrides, which influenced lithosphere development and tectonic activity. The chapter explores experimental data, including hydrogen partitioning between silicate and metallic phases, the behavior of hydride-enriched cores under high pressures, and the conductivity of such systems. It also introduces the concept of “hydrogen chimneys,” vertical degassing structures that facilitate hydrogen migration to the surface. Using high-resolution satellite imagery, researchers have identified potential degassing channels, particularly on the East European Platform, and linked them to geological and tectonic structures. Drawing on Vladimir Larin’s pioneering work, the chapter underscores the presence of substantial natural hydrogen reserves, suggesting they could meet humanity’s energy needs sustainably. It reviews the search for hydrogen flows, the structure of degassing channels, and methods for locating accessible, high-concentration hydrogen sources near potential consumers. The PHE model also contextualizes hydrogen’srole in the broader framework of Solar System formation, emphasizing its compatibility with alternative mechanisms, such as element distribution by first ionization potential.
