Phase relations in the system K 2 CO 3 -CaCO 3  have been studied in the compositional range, X(K 2 CO 3 ), from 100 to 10 mol%, at 6.0 GPa and 900-1450 °C. At 900-950 °C, the system has three intermediate compounds: K 6 Ca 2 (CO 3 ) 5 , K 2 Ca(CO 3 ) 2 , and K 2 Ca 3 (CO 3 ) 4 . The K 2 Ca(CO 3 ) 2  compound decomposes to the K 6 Ca 2 (CO 3 ) 5  + K 2 Ca 3 (CO 3 ) 4  assembly above 950 °C. The K6Ca2(CO 3 ) 5  and K 2 Ca 3 (CO 3 ) 4  compounds melt congruently slightly above 1200 and 1300 °C, respectively. The eutectics were established at 64 and 44 mol% near 1200 °C and at 23 mol% near 1300 °C. K 2 CO 3  remains as a liquidus phase at 1300 °C and 75 mol% and melts at 1425 ± 20 °C. Aragonite remains as a liquidus phase at 1300 °C and 20 mol% and at 1400 °C and 10 mol%. CaCO 3  solubility in K 2 CO 3  and K 2 CO 3  solubility in aragonite are below the detection limit (&lt;0.5 mol%).
