A detailed marked characterization of the the gumbeites found in the Precambrian of the Baltic Shield was also discussed. It was observed that the gumbeitization and ore deposition differed from the earlier processes by an increase in the CO2 fugacity and the activities of K2 and BAO in the solution. The temperature of the process was determined by fluid inclusions and chlorite geothermometers was 330-380°C for the early propylization.????
