indicating that the Pb deposition leads to the formation of small grains. Transmission electron microscopy (TEM) images confirm the topographic differences of the Pb-Cu catalyst within a single particle, as compared with the Cu catalyst (Supplementary Figs.3aand4a). High-resolution TEM (HRTEM) ima...
Isochron diagram for Tugurige pyrite samples yields initial Os isotope ratios of 1.26 ± 0.69, indicating that the crust is the source of Os and the mineralization, thus the Tugurige gold deposit is interpreted to be a crust-related deposit. However, it is still unclear whether the magmatic...
