Aragonite

  

A member of the aragonite group of minerals, Aragonite is a low-temperature, near surface mineral that forms speleothemes in caves, massive lamellar deposits by geysers and hot springs, as seafloor oolites and as a replacement mineral. It was named in 1797 for the type locality, Molina de Aragon, Spain.
