Primorsky District
Saponite is found in Ząbkowice Śląskie in Silesia, Svärdsjö in Dalarna, Sweden and in Cornwall, UK. The soap stone of Cornwall is used in the porcelain factory. Saponite is also found in the "dark rims" of chondrules in carbonaceous chondrites and seen as a sign of aqueous alteration. Europe's largest primary diamond deposit, Lomonosov, in the Primorsky District of Arkhangelsk Oblast is an area of intensive accumulation and storage of saponite at the tailings.
