Slab Melt as a Potential Source of Profiling Elements of Gold and Heavy Metal Deposits

Аннотация

Spatial/genetic control by slab magma products at gold deposits is shown in this paper by the example of granitoids in the Ust’-Kara area of the Eastern Trans-Baikal Region. The investigation performed makes it possible to take a fresh look at the problem of metal sources in the East Trans-Baikal gold deposits and to relate their formation to material flow from the oceanic lithosphere in the subduction zone, material conservation within the subcontinental mantle, and possible remobilization under large tectonic reconstructions.
