Research Field

Two new major hydrothermal fields have been discovered in the rift valley of the MAR at 13°N (Ashadze) and l6°38′N (Krasnov). The Ashadze field consists of a cluster of active hydrothermal sites associated with ultramafic rocks and located at the greatest depth in the ocean (4,200 m). By contrast, the Krasnov field consists of inactive sulfide mounds hosted in basalts. The Krasnov is the largest hydrothermal deposit on the MAR (17.4 Mt) so far discovered with iron sulfide as the principal mineral type. By contrast, Cu-Zn sulfides are the major minerals in the Ashadze deposits, which are also enriched in gold and several other metals.

Chronology of seafloor massive sulfides formation within the Pobeda hydrothermal cluster (Mid-Atlantic Ridge)

A geochronological and mineralogical study on the seafloor massive sulfides from the Pobeda hydrothermal cluster at the Mid-Atlantic Ridge was carried out. To improve the reliability of geochronological data, the 230Th/U ages were measured for both the bulk samples and monomineral separates. The oldest age ca. 52 kyr within Pobeda-1 and ca. 107 kyr within Pobeda–2 fields have been obtained. Then, several episodes of hydrothermal activity were identified within both fields up to ca. 0.3 kyr ago and up to ca. 4.3 kyr ago, respectively.

This article discusses the concept of "digital economy", its pros and cons.The following issues are addressed: what are the requirements for personnel for the "digital economy"; whether it is necessary to change the system of training; what place does the person occupy in the "digital economy".According to the authors of the paper, the presented topic contains two problematic aspects: the environment of highly intelligent technologies of human habitation and the subject (what should be the person of the digital economy era), entering into certain relations with it.The practical professional experience of the authors of the article proves the reality of creating pedagogical conditions for organizing the process of training future professionals for the digital economy, which contribute to the accumulative effect of education.
