Cavansite is a silicate mineral that contains vanadium. It's compsition is Ca(VO)Si4O10.4H2O. This sample is from Poona, India and is described as cavansite with stilbite and calcite. It is about 20 cm across.
Cavansite是一种含钒的硅酸盐矿物，其化学式为Ca(VO)Si₄O₁₀·4H₂O。该样本来自印度Poona，与Stilbite和Calcite一起描述，直径约为20厘米。
Until deep blue crystal clusters like these were discovered near Poona, India in the 1970s, the only cavansite specimens known were tiny, pale crystals from Oregon's lava flows. The Poona area of India remains the sole source for such impressive cavansite. The sample is on display at the Smithsonian Museum of Natural History.
直到20世纪70年代在印度波奥纳发现深蓝色晶体簇之前，已知的腔安石标本仅是来自美国俄勒冈州熔岩流中微小的浅色晶体。印度波奥纳地区仍然是这种壮观的腔安石的唯一来源。该样本陈列在史密森尼自然历史博物馆中。
