LEIGHTONITE Meaning and
Definition
-
Leightonite is a mineral that belongs to the silicate group and is recognized as a member of the epidote group of minerals. It was first discovered in 1976 at the Christmas mine in Arizona, United States, and was named after Alfred L. Leighton, an American mineral collector and dealer who was well-known for his contributions to the field.
Leightonite typically occurs as small, transparent to translucent crystals in a prismatic or tabular form. It is commonly found in a variety of colors such as light green, yellow-green, or colorless. The mineral has a vitreous luster and a brittle tenacity, which means it can easily be broken or fractured.
In terms of its chemical composition, leightonite is a calcium copper aluminum silicate hydroxide fluoride. It forms in low-temperature hydrothermal environments, usually associated with other secondary copper minerals. One of its distinctive features is its fluorescence under ultraviolet light, where it emits a bright green glow.
As a relatively rare mineral, leightonite is highly sought after by mineral collectors and enthusiasts due to its unique crystal habit and striking color. It possesses no significant economic value and is primarily appreciated for its aesthetic qualities.
In summary, leightonite is a silicate mineral belonging to the epidote group. It is named after American mineral dealer Alfred L. Leighton and commonly occurs in small, prismatic or tabular crystals. Known for its vibrant colors, fluorescence, and association with copper ores, leightonite is primarily valued for its beauty in the world of mineral collecting.
