The main stages of life, scientific and pedagogical activity of the outstanding geologist P.M.Tatarinov are considered.
Theoretical and applied issues of geology of ore districts are considered. It is noted that the largest ore districts are often manifested in the crustal structures in isolation, without an accompanying regional background of single-age small deposits and ore occurrences. In some ore provinces there is a repeated, polychronous manifestation of ore districts without signs of regeneration of mineral matter (deposits). Large ore districts and their deposits are the most highly organized geological objects: they serve as benchmarks of certain ore formations. The signs of such ore districts are given. Ore districts are unique mineral heterogeneities of the Earth's crust, the study of which makes it possible to reveal multilateral relations in the development of different Earth shells, the nature and influence of their evolution on the peculiarities of the manifestation of ore processes. The issues of studying ore districts in the modern conditions of economic development of the country are discussed
The issues of creation of ore deposit models for industrial evaluation of new ore occurrences identified during prospecting works are considered. The importance of their creation in connection with the new law "On Subsoil" regulating the sale of ore-bearing sites is emphasized. The main "components" of deposit models of applied value are outlined. Examples are given.
