CI Chondrites 45 Rh 134           ppb C1 Carbonaceous chondrite major and minor element compositions as given in Wasson & Kallemeyn 1988. These values are given in an effort to accurately represent the C1 chondrites as based on an array of sources and derive a revised model for the composition of the Earth.

Continental Crust 45 Rh 0.06           ppb UCC; LCC = from composite sample of 17 European greywackes analysed by ICP-MASS in nickel sulfide extract after Te co-precipitation (Hartmann, 1995). Wedepohl 1995

Depleted Mantle 45 Rh 1   0.15       ppb Estimate for the concentrations in the Depleted Mantle of most of the elements of the Periodic Table.  Ir/Rh is the element ratio/constraint used to make this estimate. Salters & Stracke 2004
Greywackes 45 Rh 0.06           ppb Total average of group averages from USA, Canada, Australia, Sri Lanka and Germany using an equal statistical weight. Wedepohl 1995
Manganese Nodules 45 Rh 0.013           ppm Average concentrations of various elements found in deep sea Manganese nodules.  Sea salt components are subtracted assuming all chloride is of seawater origin. Li 1991 Baturin 1988
Marine Pelagic Clay 45 Rh 0.0004           ppm Average concentrations for various elements enriched in Oceanic Pelagic Clays.  Compared to the element values of Shales, the Pelagic Clays are relatively similar with few exceptions.   All sea salt components are subtracted from the sample analysis assuming all chloride is of seawater origin. Li 1991 Turekian & Wedepohl 1961

Orgueil Chondrite 45 Rh 134           ppb Solar system abundances of major and minor elements as based on studies from the Orgueil Meteorite. Abundances in the Orgueil meteorite are adequately close to the C1 chondrite mean except for REE, in which case other studies will yield more preferable results Anders & Ebihara 1982

Solar System 45 Rh 0.4             Anders & Ebihara 1982 Cameron 1982
Solar System 45 Rh 0.344   0.02752     7   Rhodium data was derived indirectly from RNAA mean values for H-chondrites and then scaled to C1's via the C1/H abundance ratio. The value was found to be lower than that found for L-chondrites, yet agreed closely with derived values for Rh in H-chondrites. Mean H-chondrites were therefore used for this analysis with an estimated error of 8%. Anders & Ebihara 1982
