The analcime occurs as simple semitransparent trapezohedra to 3.5 cm across that contain cloudy white to brownish-red inclusions. |

The lake may have dried up or nearly dried up periodically, producing outward concentric zones of albite, analcime, clinoptilolite, and smectite. |
|
Early reports of leucite from this locality were shown to be an erroneous identification of analcime. |
|
On one trip he opened a huge pocket of large analcime, natrolite, and apophyllite crystals at the Big Rock quarry and shared them with everyone. |
|
Analcime may also be associated with quartz crystals, calcite, and common opal. |
|
Two zeolite minerals, analcime and natrolite, were identified, representing the first authenticated occurrence of these zeolites in Ontonagon County. |
|
Analcime occurs in both junction and pillow pockets as superb trapezohedral crystals. |
|
These include Nova Scotia's provincial mineral stilbite, as well as heulandite, analcime, chabazite, gmelinite, natrolite and thomsonite. |
|
Dawsonite, nahcolite, quartz, dolomite, alabite, illite, analcime, and kerogen were used to prepare samples. |
