Where is Celestite Mined?

Celestite is a valuable mineral with diverse applications. Beyond its role as a primary source of strontium, it holds significant appeal for collectors and jewelers due to its striking crystal formations and aesthetic qualities. Many people may wonder about the origins of this multifaceted stone. This article dives into the question of “Where is celestite mined?” and explores various locations worldwide where celestite is found, from major deposits to smaller mines that still contribute to its availability. Stay with us to uncover more about the regions that produce this remarkable mineral.

 

Where Does Celestite Come from?

Celestite (celestine) is a mineral composed of strontium sulfate (SrSO4). This mineral is often recognized for its occasional soft blue color, which inspired its name derived from the Latin word “caelestis,” meaning celestial. Alongside strontianite, celestite is a primary source of strontium, a chemical element widely used in producing fireworks and various metal alloys. Further insights about its applications are provided in celestite uses. 

Celestite deposits are found worldwide, occurring in various geological contexts that influence their characteristics and formation. These deposits are commonly associated with sedimentary environments and evaporite formations, where the mineral is frequently linked to gypsum, anhydrite, and halite. Celestite can also appear in volcanic and hydrothermal settings, contributing to its diverse formation conditions. While celestite is globally distributed, its occurrences are often concentrated in specific geological formations, providing the ideal conditions for its crystallization and growth. Further exploration of these contexts will reveal the unique attributes of celestite deposits in different parts of the world.  Below, we will explore notable global locations where celestite deposits are commonly found.

North America

North America hosts significant celestite deposits in both the United States and Canada, with occurrences tied to specific geological formations:

• Ohio: The Crystal Cave on South Bass Island is a notable site where giant celestite crystals form large geodes within the dolomite host rock of the Lockport Formation.
• Michigan: Celestite is typically found in Devonian rocks and limestone quarries near the Great Lakes, often appearing as geodes.
• Tennessee: The central region contains celestite deposits, commonly associated with sedimentary rock layers.
• Florida: Celestite occurs as a secondary mineral within phosphate-rich deposits, occasionally alongside other minerals.

In Canada, the Niagara Escarpment region of Ontario features celestite in Devonian limestone quarries, where strontium-rich mineralization is observed in sedimentary pockets.

Central & South America

Central and South America feature notable celestite deposits, with Mexico and Peru being prominent contributors. Information about the properties of this mineral are provided in Properties of Celestite.

• Mexico:

States such as Coahuila, Chihuahua, and Jalisco host extensive celestite reserves within sedimentary rock formations. Deposits are often mined on an industrial scale, primarily for the extraction of strontium used in various applications, including pyrotechnics and metal alloys.

• Peru:

Celestite is occasionally found in hydrothermal vein deposits and associated with other sulfate minerals, reflecting the geological diversity of the region.

Europe

Europe hosts several notable celestite deposits, distributed across different countries, often linked to sedimentary and evaporite formations:

• Spain:

Granada (Cerro de Gorría) and other southern regions have historically been significant producers of celestite. Deposits are typically mined from bedded layers within evaporite sequences. Catalonia and Aragon feature strata-bound deposits associated with gypsum- and halite-rich rocks.

• United Kingdom (England):

Southwest England, particularly Somerset and Gloucestershire, contains celestite occurrences within Triassic red beds. Near Bristol, geodes sometimes contain celestite and calcite, known locally as “Bristol Diamonds.” Northern England has isolated occurrences in sedimentary formations, though these are less prominent today.

• Germany:

Historically produced celestite from sedimentary basins, though modern activity is mainly limited to collectors’ sites.

• Italy (Sicily):

Minor celestite deposits are occasionally found in sulfur mines within evaporite sequences.

• Poland:

Permian and Triassic sediments host celestite occurrences, but production remains limited and primarily caters to collectors

Africa

Answering the question “Where is celestite mined?” is impossible without mentioning Africa. This region features several noteworthy celestite deposits across, with significant geological diversity:

• Tunisia:

Historically recognized for celestite production from sedimentary evaporite sequences.

• Morocco:

Celestite is found in mineral-rich deposits, often alongside fluorite and barite, though it is not produced in substantial quantities.

• Madagascar:

The Sakoany deposit on the northwest coast is internationally renowned for its striking sky-blue celestite geodes. These geodes often feature large, highly transparent crystals and are sought after in the mineral market.

• Mali and Tanzania:

Both countries occasionally report celestite occurrences in evaporite or vein-type deposits, but they are not considered major producers.

Middle East & Central Asia

The Middle East and Central Asia are home to notable celestite deposits, reflecting the region’s diverse geological features:

• Iran:

As one of the leading celestite producers in the region, Iran boasts substantial strontium resources. Deposits are primarily found in evaporite sedimentary sequences, particularly in central and southern parts of the country.

• Turkey:

Celestite occurs in evaporite series across various regions, although its production is inconsistent and often secondary to barite extraction.

• Afghanistan & Pakistan:

These countries see small-scale mining and collecting activities, particularly in pegmatites and secondary deposits. Some specimen-quality crystals from these areas occasionally appear in the mineral market, valued for their unique characteristics.

East & Southeast Asia

East and Southeast Asia contain several celestite deposits, with China being the most significant contributor in the region:

• China:

Provinces such as Hubei and Yunnan are known for celestite deposits, which are utilized for both industrial purposes and the specimen market. These deposits are found in sedimentary layers and hydrothermal environments, showcasing a range of geological conditions.

• Myanmar (Burma), Vietnam, and Other Southeast Asian Nations:

While minor occurrences of celestite have been documented, these areas are not major contributors on a global scale.

Celestite occurrences in Oceania are relatively limited, with Australia and New Zealand being the primary locations:

• Australia:

Celestite is found in evaporite deposits and sedimentary basins, though its production is minimal and often overshadowed by the extraction of other minerals.

• New Zealand:

Minor occurrences of celestite are typically found alongside other sulfate minerals, and they hold little commercial significance.

 

Iran; a Region with Rich Celestite Deposits

Iran stands out as one of the world’s leading holders of celestite reserves, supported by its vast mineral wealth. While the country covers only 1.1% of the world’s land area and represents 1.05% of the global population, it boasts 7% of its mineral resources. The largest celestite mine in Iran, representing over 95% of the country’s reserves, is located in the Orouneh district of Sorkheh County, Semnan Province. Celestite in Iran is typically embedded in sedimentary rocks and frequently coexists with other minerals such as halite, anhydrite, and gypsum. These deposits are extracted and processed into various forms, including lumps, concentrates, granules, and powders, catering to diverse industrial needs.

The distribution of celestite deposits in Iran reflects its extensive geological diversity. Semnan Province hosts several prominent mines, including those in Aradan and Sorkheh, making it a significant hub for celestite extraction. Other notable locations include:

• Dehloran in Ilam Province;
• Behbahan;
• Shahrood;
• Neyshabur;
• and Varamin.
