   Summary Author:  Monikeli Wippel

    Varvite Park is a geological monument in the town of Itu – located
   about 60 miles (95 km) northeast São Paulo, Brazil. The artificial rock
   outcrops in an abandon quarry are the result of mining activity dating
   back to the early 18th century. Following many years of mining, this
   area was converted into a municipal park in 1995 and now represents a
   milestone in the protection and valuing of  geoheritage in Brazil.

   The photo above shows a  varvite present in the park. Varvite is a
   name used by geologists to designate a kind of sedimentary rock formed
   by the repetitive succession of pairs of layers or  laminas
   deposited over the years. The name "varvite" is derived from the word
   “ varve” of Swedish origin. It is generally used to designate
   rhythmic sedimentary seasonal deposits, which said another way means
   they are controlled by how the deposits formed based on variation in
   weather throughout the year. The most known type of varve is
   represented by laminas or layers of sediments in fractions of  sand,
   silt, and clay. Photo taken on April 22, 2022.
