Analcime may also be associated with quartz crystals, calcite, and common opal. |
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. |
Two zeolite minerals, analcime and natrolite, were identified, representing the first authenticated occurrence of these zeolites in Ontonagon County. |
The analcime occurs as simple semitransparent trapezohedra to 3.5 cm across that contain cloudy white to brownish-red inclusions. |
Early reports of leucite from this locality were shown to be an erroneous identification of analcime. |
The lake may have dried up or nearly dried up periodically, producing outward concentric zones of albite, analcime, clinoptilolite, and smectite. |
