text: # Hsianghualite
  
  Hsianghualite is a tectosilicate (framework silicate) of lithium, calcium and beryllium, with fluorine, a member of the zeolite group. It was discovered in 1958 and named for the type locality, Hsiang Hua, 香花, meaning fragrant flower.
  
  ## Structure
  
  Structure is analogous to that of analcime with Be and Si in tetrahedral co-ordination forming a three-dimensional framework. Its space group is $I2_13$ (Previously reported as $I4_132).$ Unit cell parameters are a = 12.879 or 12.897, and Z = 8.
  
  ## Environment
  
  It occurs within phlogopite veins in the light-coloured band of green and white banded metamorphosed Devonian limestone which has been intruded by beryllium-bearing granite. Associated mineral include fluorite, liberite, chrysoberyl, taaffeite and nigerite.
  
  ## Localities
  
  Hsianghualite has been found only at the type locality, the Xianghualing Mine in Linwu County, Hunan Province, China.
