Wanda (pronounced vanda) is an Argentine town located at a latitude of 25 ° 58' South and a length of 54 ° 34' West. The municipality based on it is called Colonia Wanda, however, the town is usually called Wanda to dry. The municipality has a population of 12.779 inhabitants.

Wanda Mines, elevation 211 m. asl, located at the northwest of Province of Misiones in the Iguazú Department, a few kilometers of Paraná river.
Extraction and sale of semi-precious stones.

Enormous basaltic formation that covers a big zone of the Misiones province in Argentina, part of Uruguay (artigas department), part of south Brazil and Paraguay. This formation has bubbles (geodes) of quartz (some with calcite) such as amethyst, agates, etc. Wanda mine is one of the several extractions of the zone.

Deposits of amethyst and agate: druses or in basalt geodes; agates are also extracted to the South. Amethyst feature twin according to law of Brazil and contain Fe, traces of Al, Li, Ca, Mg, Cr, Mn, Ti and Cu. Usually have colors lilac pale, blue and dark purple. Some fade from exposure to sunlight. They have pyramidal ends. The geodes are usually awarded by celadonite green outside. The agates have variable microporosity and banded.
