About Yuanfuliíta
Yuanfuliite is a rare borate recognised as a species in 1994. Miguel Calvo documented its presence here in Jumilla in 2012 (Minerales y Minas de España, vol. 5, pp. 649–650). The association is rich and mineralogically complex.
About the locality
Closed. One of the best-known Spanish deposits of this ultrapotassic environment, renowned for its apatites and for rare parageneses in small cavities in the rock. Although never a mass producer, it has yielded well-formed specimens much appreciated by collectors. Its closure is due to the area being declared a protected area, after several bat colonies chose it as a refuge. It has also been a regular destination for collectors, and the plundering of mineral specimens has been cited as grounds for the final closure.
