This keyword data block is written by the DUMP operation. It is intended to be used to reinitialize simulations at the point that the DUMP command was executed or to transfer surface-assemblage compositions between IPhreeqc modules.
The SURFACE_RAW data block contains a complete listing of the internal data structures that define a surface assemblage. SURFACE_RAW data blocks are written by DUMP and read by PHREEQC without user modification. The formats should be considered dynamic because future modifications to PHREEQC could result in additional data that are included in the SOLUTION_RAW data block.
