Lithium Systems Geology


Lithium system understanding is deep understanding

Lithium systems modelling integrates models of lithium transport with 3D geomodels of your project area to generate a genetically-based system model for the form and evolution of your lithium project. Transition Elements' lithium systems approach encompasses describing and assessing all contributions to the lithium supply, from their igneous origins through weathering, transport and deposition, to leaching, brine movement and evaporation. Lithium systems modelling provides a conceptual framework for developing exploration plans to delineate accumulations, and study programmes to elucidate lithium deposit history and development. By using a systems-thinking approach, it is easier to see what is known and understood, and focus scientific effort on what remains important, yet obscure.

Time is of the Essence

Inherent in all liquid resource exploitation is the appreciation of time. The timescale necessary for the formation of the accumulation is not the time scale on which exploitation will occur. It is valuable to develop a clear understanding of the timescales over which the different processes affecting your project occur, including leaching, evaporation, density stratificiation and convection. Some of these processes will have negligible effect over production time scales, but others will be important. These factors can have significant impact on the integrity of the brine body and the environmental impact of water movement and mixing within the reservoir and catchment area.


Rock Solid

Essential to describing the distribution of liquid resources is a model of the stratigraphy, comprising a realistic 3D model of the heterogeneity in permeability and porosity. This facilitates more realistic mapping of the flow pathways taken by mobile lithium brines, and the identification of accumulations in lithium traps. Connectivity through the basin can be mapped, and the relative timeframes of flow through different lithologies can be integrated to produce more confident assessments of where the brines came from, and where they went. Source to sink, modelling your project as an integrated system of interacting elements generates not just quantification, but understanding. With a quantified lithium systems model, you can plan your project. With a deeper understanding, you know how good your plan is.

Industrial Time and Magic

Transition Elements' LiSys software tools are an ongoing technology development project. By applying our understanding of migratory liquid resources and their behaviour in porous reservoirs, we can build detailed geological models of your lithium brine project, and examine the mobilisation patterns of lithium-bearing fluids moving through complex sedimentary architectures. These models can provide input to reserves assessments and production planning, increasing certainty, quantifying value, and lowering risk.
