Gismondine is a mineral with the chemical formula CaAl 2 Si 2 O 8 ·4(H 2 O). It is a zeolite or hydrated alumino-silicate. It forms colorless, bipyramidal crystals of orthorhombic symmetry. Gismondine was named for Italian mineralogist Carlo Giuseppe Gismondi (1762–1824). It has been found in Iceland, Ireland, and Italy.

水钙沸石（Abrazite）是沸石族中的稀有矿物，在爱尔兰和冰岛的玄武熔岩中发现了许多与菱沸石、杆沸石、钙十字沸石共生的水钙沸石。

In 2001, a barium-dominant gismondine, "gismondine-Ba" has been discovered in slag material (of course not approved, as valid species, by IMA CNMNC). The Ca analogue of gismondine-Sr was approved in 2021. As of 2021 there are now IMA–CNMNC approved mineral symbols (abbreviations) for each mineral species, useful for tables and diagrams.

Gismondine是一種化學式為CaAl2Si2O8·4（H2O）的礦物。 它是沸石或水合矽鋁酸鹽。 它形成正交斜對稱的無色雙錐體晶體。 Gismondine以意大利礦物學家Carlo Giuseppe Gismondi（1762-1824）的名字命名。 它已經在冰島，愛爾蘭和意大利被發現。 拍照即可即時識別岩石/寶石/礦物並分析其屬性，快速了解其 特性、市場價值、收藏建議、護理、真假辨別和健康風險 等。 深入探索 岩石類型、特徵和形成 方面. 拍照即可即時識別岩石並獲得關於 特性、市場價值、收藏建議、 …

The gismondine framework topology consists of two sets of intersecting, doubly connected 4-membered rings linked into double crankshaft chains (dcc on the GIS page), like those of phillipsite. These sets of double crankshaft chains that run parallel to the a -axis and to the b -axis are related by a 4 1 axis forming the GIS framework.

Gismondine, rare mineral in the zeolite family. Many specimens have been found in Ireland and Iceland in basaltic lavas, along with such other zeolites as chabazite, thomsonite, and phillipsite. Gismondine forms colourless, bipyramidal crystals of orthorhombic symmetry; it is a …
