On July 3rd, 1999, the Post Authority of Peru: Serpost issued the set of three stamps shows two minerals and one fossil mollusc on it, to represent geological treasures of the country. A similar set, but unfortunately without any fossils, was issued three years later, on July 3rd, 2002 (Michel No. 1836-1838)
The following text is a quote from brochure issued by Serpost in 1999.
Virgotrigonia peterseni (Alleman, 1985).

| Fossilized mollusc Virgotrigonia peterseni on stamp of Peru 1999 MiNr.: 1702, Scott: 1232. |
This specimen was collected and described by Vera Allerman in 1985 at Cerro La Virgen, Morro Solar, in the district of Chorrillos in Lima.
The name of the new species was given in honour of the prominent geologist Georg Petersen in recognition of his efforts which made possible the discovery and description of this new genus.
Other species of this genus are known in Chile and Argentina.
The fossiliferous formations at Morro Solar, Chorrillos, deserve to be protected.
Vera Alleman’s collection is deposited at the Museum of Natural History of the University Ricardo Palma.

Galena - PbS, cubic system. Location: Casapalca mine, Lima. The Casapalca mine is a producer of lead, zinc and silver ores. It is located 130km east of Lima, at an altitude of 4,495 m. Production of lead-zinc ores, rich in silver, dates back to Spanish colonial time and continues to the present day. The stratigraphic sequence consists of sedimentary and volcanic rocks of Upper Cretaceous to Quaternary Age. This sequence was strongly folded and intruded by various igneous bodies. The ore deposits consist of persistent veins which cut the entire sequence. The economic mineralization consists of galena, sphalerite, tetrahedrite and chalcopyrite. Guido del Castillo's private collection. |
Scheelite- CaWO4, tetragonal system. Location: Tourmaline mine, Piura. The Turmalina mine is situated in the district of Canchaque, department of Piura. The mineralization was deposited within a circular body of tourmaline set in a large tonalite intrusive. The ore consists mainly of molybdenite and chalcopyrite in the upper part of the deposit, with pyrite, arsenopyrite, sphalerite, wolframite and scheelite occupying the lower portion. Mr. Guido del Castillo's private collection. |
