tavalahustites

Tavalahustites are a rare mineral species that belongs to the sulfide class of minerals. They are composed of calcium, thorium, and lead sulfides, and are often found in alkaline igneous rocks. Tavalahustites have a distinctive crystal structure, which is typically tabular or prismatic in habit.

The mineral was first discovered in the 1970s in Finland, specifically in the municipality of Taivalvaara in the province of North Ostrobothnia. It was named after the Taivalvaara district, where it was first found. The mineral has been classified as a species within the sulfide group of minerals, due to its chemical composition and crystal structure.

Tavalahustites are found in limited quantities, making them a relatively rare mineral. They have been identified in several locations around the world, including Finland, Norway, and the United States. The mineral often occurs in association with other sulfide minerals, such as galena and pyrite.

Tavalahustites have several notable properties that make them of interest to geologists and mineralogists. They exhibit a metallic luster and are typically opaque to translucent. Their colors range from lead gray to brown, and they can be slightly magnetic.

Research on tavalahustites has provided valuable insights into the geological processes that shape the Earth's crust. The mineral's presence in certain rock formations indicates a specific set of conditions, such as the presence of thorium, which is a rare element. The study of tavalahustites continues to contribute to our understanding of the Earth's geological history and the formation of economic deposits.
