This paper discusses the mathematical modelling of laboratory controlled sedimentary systems that physically simulate organo-metal complex and metal sulphide formation in a reducing environment. The paper provides the general theoretical framework for modelling systems of this type. Further papers will describe specific models of specific laboratory-controlled sedimentary systems. Techniques of modelling the following processes are described: sedimentation; supply of metal species (Cu(II) and Zn(II) ); generation of H2S and chelating agents in an organic-rich zone by bacterial action; diffusion of chemical species through the sediment; formation of metal sulphides and metal complexes, and the competition between these two processes. The diffusion and chemical interactions are represented by a set of linked partial differential equations and algebraic relationships.
