.... Although the biota provides remarkable insights into the early evolution of complex macroeukaryotes in the Ediacaran, the uncertainty in its age has hampered any robust biological evaluation. We resolve this issue by applying a petrographic-guided rhenium-osmium (Re-Os) organic-bearing sedimentary unit...

... suitable for zircon U-Pb dating, making the direct dating of these deposits a challenge. Rhenium-osmium geochronology has been demonstrated to be a powerful tool for constraining the depositional age of sedimentary rocks, such as marine mudrocks ( Creaser et al., 2002 ; Selby et al., 2009 ), organic...

... of America 2022 Rhenium (Re) and osmium (Os) are linked through β-decay of 187 Re to 187 Os. Due to the incompatible behavior of Re during mantle melting, both oceanic and continental crust (OC and CC, respectively) have large Re/Os ratios and become enriched in 187 Os over time ( Becker and Dale...

... diffraction (EBSD) methods. Elevated contents of rhenium (0.2 to 0.4, sometimes up to 1.1 wt.%) form linear zones from several to tens of micrometres wide and up to hundreds of micrometres long parallel to the elongation of molybdenite flakes. In most cases Re-rich zones are composed of the rhombohedral (3 R...
