Material: Fibrous ferrierite

GENERAL INFO IMAGE

Provenance: Lovelock (Nevada, USA)

Description: The zeolite-rich tuff deposit of Lovelock, Nevada, USA is the largest occurrence of diagenetic ferrierite-Mg. Ferrierite hosted in these rocks displays a fibrous morphology. This raw material is used to produce light weight cements.
