show the appropriate hyperbolic relationship (Fig. 2b) predicted by mixing of unmodified terrestrial and meteorite debris. We propose that weathering of meteoritic debris caused preferential liberation of certain elements, depending on the stability of the host minerals in the Hadean atmosphere and hydrosphere. For example, most Cr in iron-meteorite is hosted by troilite (FeS), whereas all W is found in the FeNi metal phase 17. Although W isotopes cannot be used to directly identify the nature… CONTINUE READING
