Sulphur geodynamic cycle

Evaluation of volcanic and hydrothermal fluxes to the surface environments is important to elucidate the geochemical cycle of sulphur and the evolution of ocean chemistry. This paper presents S/(3)He ratios of vesicles in mid-ocean ridge (MOR) basalt glass together with the ratios of high-temperature hydrothermal fluids to calculate the sulphur flux of 100 Gmol/y at MOR. The S/(3)He ratios of h...

Tectonics of early Earth: Some geodynamic considerations

Today, plate tectonics is the dominant tectonic style on Earth, but in a hotter Earth tectonics may have looked different due to the presence of more melting and associated compositional buoyancy as well as the presence of a weaker mantle and lithosphere. Here we review the geodynamic constraints on plate tectonics and proposed alternatives throughout Earth’s history. Observations suggest a 100...

[Physical development of schoolchildren in Moscow and Kiev].

Physical development was assessed in 2329 Moscow schoolchildren and 1433 Kiev ones aged 8 to 11 and 15 to 17 years. The Moscow and Kiev children aged 8 to 11 years did not differ in the basic anthropometric indices of physical development and force capacities. Gracilization processes were prevalent in the Kiev schoolchildren. Statistically significant differences were established in respiratory...

SNAP and SPAN: Prolegomenon to Geodynamic Ontology

Current approaches to the formal representation of geographical reality are characterized by their static character. GIS representations are representations of the world at a given time, reflecting the fact that geographic information systems have their roots in printed maps. Yet, geographical reality, like all other domains of reality, is essentially dynamic. We here outline a theory that is d...
