High-quality graphite occurrence that was indicated by an airborne electromagnetic anomaly (approx. 0.5 × 1 km in size), and subsequently was located during fieldwork by electromagnetic measurements.
The flake graphite is hosted by Paleoproterozoic quartz-feldspar gneiss and amphibolite that have been subjected to retrograde metamorphism (granulite facies regressing to greenschist facies). Equilibration conditions are calculated at ca 5 kbar and 740 °C.
Located about 50 km from Mikkeli.
Note: coordinates fairly approximate.
