Abstract

This article provides the first up-to-date overview of the history of fossil resin finds in the southern part of Sakhalin Island. On the base of little-known facts and casual references scattered in geological literature, main locations of the amber-like fossil resins are reviewed and described. Peculiarities of their molecular composition were studied, and, for the first time, it has been done for resins from Moneron Island. The assumption of S. S. Savkevich about mineralogical non-identity of resins from the coast of the Sea of Okhotsk and the Naiba river basin was analytically confirmed. It is shown that the resins are represented not only by a ductile variety — rumenite, but also by brittle ones — gedanite and retinite, which can’t be used as jewelry raw materials.
