 | | Norrlammala and Nummi-Pusula are situated in the Uusimaa Belt, southwestern Finland, and Rummukka and Ukonkangas in the Virtasalmi district, southeastern Finland. |
 | | At Virtasalmi the marbles are mainly dolomitic in composition. |
 | | The metamorphic assemblages of the marbles give 650°-760°C at 5 kbar, whereas according to the calcite-dolomite thermometry the temperatures are slightly lower, 580° to 625° C. The Svecofennian marbles are interpreted to have been deposited mainly as autochthonous sediments, in a relatively deep marine environment. |
