Powellite
Powellite is a calcium molybdate mineral with the chemical formula CaMoO4. It crystallizes in the tetragonal crystal system and is classified under the Strunz classification as 7.GA.05. This mineral is typically yellow to orange in color and exhibits a vitreous luster. It has a hardness of approximately 4 to 4.5 on the Mohs scale and a specific gravity of around 4.2 to 4.5. Powellite is a nesosilicate mineral, though it is more specifically a molybdate, and is known for its prismatic crystal habit. It is commonly found in hydrothermal veins and is associated with other molybdenum-bearing minerals.

Overview
Powellite is a calcium molybdate mineral with the chemical formula CaMoO4. It crystallizes in the tetragonal crystal system and is classified under the Strunz classification as 7.GA.05. This mineral is typically yellow to orange in color and exhibits a vitreous luster. It has a hardness of approximately 4 to 4.5 on the Mohs scale and a specific gravity of around 4.2 to 4.5. Powellite is a nesosilicate mineral, though it is more specifically a molybdate, and is known for its prismatic crystal habit. It is commonly found in hydrothermal veins and is associated with other molybdenum-bearing minerals.
Etymology
Powellite is named after John Wesley Powell, an American geologist and explorer. The mineral was named in his honor to recognize his contributions to the field of geology.
Geological genesis
Powellite typically forms in hydrothermal environments, often associated with the oxidation zones of molybdenum deposits. It is commonly found in association with other molybdate minerals and is a secondary mineral that can form through the alteration of primary molybdenum sulfides.
Occurrence
Powellite is found in various localities worldwide, particularly in association with hydrothermal veins and molybdenum deposits. Specific type localities are not provided in the facts.
Spiritual meaning and crystal therapy
Spiritual meaning
Powellite is traditionally associated with clarity and insight, symbolizing the pursuit of truth and the illumination of hidden knowledge.
