What is Chiastolite?
Chiastolite is a unique and fascinating variety of the mineral andalusite, characterized by its distinctive cross-shaped black inclusions of graphite. Its chemical composition is Al2SiO5. These graphite inclusions create an unmistakable pattern that makes chiastolite highly sought after by collectors and enthusiasts alike. Chiastolite is primarily found in metamorphosed sediments rich in graphite, such as those discovered in areas around Georgetown, California.
In some regions, such as Mogok in Myanmar, chiastolite crystals have undergone pseudomorphic alteration by a mixture of muscovite, paragonite, and margarite. Interestingly, the calcium-rich margarite tends to form along the graphite-rich crosses or bands within the stone. This occurrence is significant mineralogically, as it presents an equilibrium assemblage of all three white mica phases.
Formation of Chiastolite
The formation of the cross-shaped inclusions within chiastolite is a topic that has intrigued geologists for decades. The most widely accepted theory, put forward by Frondel in 1934, suggests that these inclusions form due to a selective attachment of impurities at the rapidly growing corners of andalusite crystals. As the concentration of these impurities, primarily consisting of graphite, increases, it slows down the growth of the crystal.
This results in a re-entrant feature being formed as the graphite is absorbed into the growing andalusite porphyroblast. The repeating cycle of growth, retardation, and growth again creates the striking feather-like pattern of graphite along four radiating “arms.” This process gives chiastolite its distinctive and iconic appearance.

Andalusite and Its Relationship with Chiastolite
Andalusite, the parent mineral of chiastolite, is an aluminium nesosilicate mineral with the chemical formula Al2SiO5. The name “andalusite” was originally given by Delamétherie, who mistakenly believed that the mineral came from Andalusia in Spain. It was later discovered that the specimens actually originated from El Cardoso de la Sierra in Guadalajara, not Andalusia.
Andalusite is trimorphic, which means it shares the same chemical composition as two other minerals—kyanite and sillimanite—but exists in different structural forms depending on the temperature and pressure conditions. At higher temperatures and pressures, andalusite can transform into sillimanite.
These minerals provide important geological clues about the temperature and pressure conditions under which their host rocks were formed. For more information on these minerals, you can visit our page on andalusite.

Frequently Asked Questions About Chiastolite
What Chakra Is Chiastolite Associated With?
Chiastolite is often linked to the root chakra, which is associated with grounding and stability. The stone’s energy is believed to help one open up their root chakra and connect with the energies of Mother Earth, promoting a sense of security and balance.
Where Is Chiastolite Found?
Chiastolite was first discovered in Andalusia, a province in Spain, which also gave its name to the parent mineral andalusite. Significant deposits of chiastolite have also been found in South Australia, Brittany in France, and the Transbaikal region of Russia, particularly in the areas around Nerchinsk and along the shores of the Argun River.
