... 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-rich limestones ( Rooney et al., 2012 ; Kendall et al., 2013 ), lacustrine...

... 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...
