Metallogeny of the marginal sea lithosphere (Northeast Russia)

Abstract

Metallogenic model of the margin sea lithosphere is a complex combination of rejuvenated mineralization of the Precambrian basement terrains, of different types of sulfidized zones Verkhoyansk (Pz-J) sedimentary formations and the post-magmatic generations in accretion (J-K1) and post-accretion (K1-Cz) structures. The intensity of mineralization and unique ore regions are closely related to the features of these combinations. Favorable combinations may be identified as a result of geochemical isotopic ore elements. The influence (heredity) of Precambrian mineralogical and geochemical lines is evident in pre- and sin-accretion (collision) structures; in post-accretion (covered) structures this effect is markedly reduced.
