Abstract:
Oil and especially the related associated bitumen, in particular, are characterized by high metal contents with a predominance of V, Ni, and Zn that make up a specific “oil” assemblage. Based on the prevalence of one of these metals, we can identify the vanadium, nickel, and zinc types of oil not only in oil fields, but also in large oil provinces of Russia. The concentration of metals in oils may acquire metallogenic significance. In this respect, vanadium-type oil is particularly productive.
