Pentagonite is a rare silicate mineral with formula Ca(VO)Si4O10·4(H2O).It was named for the unusual twinning which produces an apparent five-fold symmetry. It is a dimorph of cavansite. Pentagonite was first described in 1973 for an occurrence in Lake Owyhee State Park, Malheur County, Oregon. It has also been reported from the Pune district of India. It occurs as fracture and cavity fillings in tuff and basalt. It occurs with cavansite, heulandite, stilbite, analcime, apophyllite and calcite.

  • La pentagonite è un minerale raro non radioattivo, scoperto nel 1973 presso il parco statale del lago Owyhee, nella contea di Malheur in Oregon. Deriva il suo nome dal greco, attualmente si conosce la sua diffusione in India e negli stati occidentali degli Stati Uniti. (it)
  • Пентагонит — редкий минерал из класса силикатов (филлосиликатов), диморфен с каванситом. Открыт в 1973 году. Название было дано из-за того, что у минерала пять плоскостей симметрии («пента» — «пять», «гониос» — «угол»). (ru)
