Summary:Chemical analyses of brines from the Paris Basin have been used to simulate mixing between two waters, the Keuper formation water and the Dogger formation fluid. The main results are: 1) Pb, Zn, Cu, Fe and Ba are transported essentially as aqueous chloride complexes, 2) organic matter (acetate) does not play a significant role in metal transportation but can be effective for pH buffering, and 3) mixing between these two waters may result in saturation with respect to many typical MVT sulphides, e.g. galena, sphalerite, etc. [R.A.H.]
