Description
Summary:Transportation of volatile trace elements such as Bi, Tl and In in chondrite parent bodies was studied by computer simulation. Experimentally determined gas permeability of chondrites and a plausible thermal history of a parent body was used in the calculation. The effect of a carrier gas was found to be insignificant. Within the uncertainty of the thermodynamic data, fractionation of these volatile trace elements during thermal metamorphism is possible. More accurate thermodynamic data are required to settle the issue whether the fractionation of volatile trace elements was due to a nebula condensation process or due to thermal metamorphism in a parent body.
