Vivianite has scientific uses. It is an environmental indicator: "Vivianite's presence in sediments can reveal past environmental conditions, including oxygen levels, pH, and the availability of iron and phosphorus. This information aids in reconstructing paleoclimate and understanding past ecological changes". It is a geochemical tracer: "Researchers studying the transportation and fate of iron and phosphorus in aquatic environments can utilize vivianite as a natural tracer due to its specific formation conditions and reactivity". Vivianite is a paleontological tool: "Fossilized vivianite alongside fossils of organisms like fish or plants can provide insights into ancient ecosystems and the interactions between organisms and their environment. Besides the scientific uses, we have the use of vivianite as a gemstone and for mineral collection. The web site is also mentioning the vivianite cultural use, with associated symbolic values.
