Lead isotope ore provinces of eastern Transbaikalia and their relationships to regional structures: Results of high-precision MC-ICP-MS study of Pb isotopes

Super large mineral deposits and deep mantle dynamics: The scenario from Southeast Trans‐Baikal region, Russia

“…The high‐magnesium monzonite magma that generated the K‐adakites associated with the ore deposits is considered to have formed through delamination of crustal material and mantle melting (Berzina et al, ). A similar conclusion was also arrived at by Chugaev et al () on the gold and molybdenum mineralization where the authors invoked the presence of geochemical reservoirs in the mantle. Based on Pb isotope modeling, the involvement of subducted oceanic crust was inferred in the formation of gold deposits in Darasun belt and the molybdenum ores in Bugdaya.…”

“…These conclusions are supported by seismic tomographic data that show stagnant oceanic slab in the mantle transition zone at a depth of 410–670 km. A similar situation was also envisaged for the Akatui and Noion‐Tologoi deposits based on Pb isotope ratios of galena (Chugaev et al, ; Sasim et al, ). The formation of uranium deposits of Streltsovka type is also correlated to a similar mechanism (Shatkov, ).…”
