What mineral is apophyllite?
apophyllite, potassium-calcium fluoride-silicate mineral that is related structurally to the zeolite family of aluminosilicates. Like the zeolites, it has a high water content, although apophyllite has no aluminum in its chemical composition, which is approximately represented by the formula Ca4KFSi8O20ยท8H2O.
Is apophyllite a rock or mineral?
The name apophyllite refers to a specific group of phyllosilicates, a class of minerals.
How do you identify apophyllite?
PHYSICAL CHARACTERISTICS:
- Color is clear, white, green, yellow, pink, violet or rarely brown.
- Luster is vitreous to pearly on cleavage surfaces.
- Transparency: Crystals are transparent to translucent.
- Crystal System is tetragonal; 4/m 2/m 2/m; natroapophyllite is orthorhombic, 2/m 2/m 2/m.
What type of rock is apophyllite found in?
Introduction: apophyllite is a group name for the three end-member species fluorapophyllite, hydroxyapophyllite and natroapophyllite. These are commonly found with calcite and various zeolite minerals in amygdaloidal cavities or secondary veins developed in altered basic igneous rocks.
What element is apophyllite associated with?
Metaphysical Properties Apophyllite is associated with both the element of wind, but also has an interesting relationship with water energies. Apophyllite contains water, and this may be why it is thought to have powerful cleaning properties and is highly sought by healers.
What is Astrophyllite made of?
Astrophyllite is a very rare, brown to golden-yellow hydrous potassium iron titanium silicate mineral. Belonging to the astrophyllite group, astrophyllite may be classed either as an inosilicate, phyllosilicate, or an intermediate between the two.
Are zeolite and apophyllite the same thing?
Apophyllite appears very similar to the zeolites, and is sometimes even confused with them. However, the physical structure of Apophyllite is different, with tetrahedrons aligning in sheets as a phyllosilicates, as opposed to the zeolites which are tectosilicates.
Is Nuummite the same as Astrophyllite?
Astrophyllite looks very similar to the minerals Nuummite and Arfvedsonite. The colors are very similar, as all the crystals above offer metallic lusters of blues, oranges, and coppers. The best way to identify and differentiate Astrophyllite is to look for tiny striations throughout a dark brown or black matrix.
What is the difference between Astrophyllite and Arfvedsonite?
When tumbled or polished, Astrophyllite will appear a milky white, light brown or gray color. The common difference between Arfvedsonite and Astrophyllite is the flash seen inside of Astrophyllite is a gold color whereas Arfvedsonite has both the gold flash as well as silver or blue.

What does Astrophyllite look like?
Astrophyllite Appearance Astrophyllite is a soft white or brown stone that has golden blades. It is easy to identify in raw form with its striking golden spikes radiating outwards. When tumbled or polished, Astrophyllite will appear a milky white, light brown or gray color.
Where can I find apophyllite?
Though it is found worldwide in volcanic zeolite environments, the Indian traprock quarries have produced enormous quantities of this mineral in all different shapes, sizes, and colors, making Apophyllite easily obtainable and very affordable. Apophyllite was originally regarded as a single mineral, with a variable ratio of fluorine to hydroxyl.
What is the new name for apophyllite?
The new mineral names are Apophyllite- (KF) [instead of Fluorapophyllite], Apophyllite- (KOH) [instead of Hydroxyapophyllite], and Apophyllite- (NaF) [instead of Natroapophyllite]. Although use of the original names is now discouraged by the IMA, these names are still used and referenced, with the new names frowned upon by many collectors.
What is apophyllite made of?
Apophyllite is named from a combination of the Greek word ” apo ” – to be off, and ” phyllos ” – leaf, alluding to the property of this mineral that it exfoliates (flakes apart like a leaf) when heated due to loss of water in its structure. Hydrous calcium potassium fluoro-hydroxyl-silicate.
