What is Paravauxite?

Paravauxite is a rare mineral that captivates geologists and mineral enthusiasts alike. Its unique properties and fascinating history make it a subject of interest. Let's dive into some intriguing facts about this mineral.

  1. Paravauxite is a phosphate mineral. It belongs to the vauxite group and is chemically composed of iron, aluminum, and phosphate.

  2. This mineral was first discovered in Bolivia. Specifically, it was found in the Siglo Veinte Mine in Llallagua.

  3. Paravauxite forms in hydrothermal veins. These veins are typically associated with tin deposits.

  4. The mineral is named after Vauxite. The prefix "para-" indicates its close relationship with vauxite.

  5. Paravauxite crystals are typically tabular. They often appear as elongated, flat plates.

Physical Characteristics of Paravauxite

Understanding the physical characteristics of paravauxite can help in identifying and appreciating this mineral. Here are some key features.

  1. Paravauxite has a white to pale green color. This subtle coloration makes it distinct from other minerals.

  2. The mineral exhibits a vitreous to pearly luster. This gives it a shiny, glass-like appearance.

  3. Paravauxite has a hardness of 3.5 to 4 on the Mohs scale. This means it is relatively soft compared to other minerals.

  4. It has a specific gravity of 2.3 to 2.4. This is a measure of its density compared to water.

  5. Paravauxite is transparent to translucent. Light can pass through it, making it somewhat see-through.

Chemical Composition and Structure

The chemical composition and structure of paravauxite are what make it unique. Let's explore these aspects.

  1. Paravauxite's chemical formula is FeAl2(PO4)2(OH)2·8H2O. This indicates it contains iron, aluminum, phosphate, hydroxide, and water.

  2. The mineral has a monoclinic crystal system. This means its crystal structure is shaped like a skewed rectangle.

  3. Paravauxite is often found in association with other minerals. These include vauxite, wavellite, and variscite.

  4. The mineral's crystal habit is typically prismatic. This means its crystals are elongated and column-like.

  5. Paravauxite can exhibit twinning. This is when two crystals grow together in a symmetrical manner.

Historical and Geological Significance

Paravauxite has a rich history and significant geological importance. Here are some notable points.

  1. The first documented discovery of paravauxite was in 1922. This makes it a relatively recent addition to the mineral world.

  2. Paravauxite is often found in tin-rich hydrothermal deposits. These geological settings are crucial for its formation.

  3. The mineral is named in honor of George Vaux Jr.. He was an American mineralogist who contributed to the study of phosphate minerals.

  4. Paravauxite is considered a secondary mineral. This means it forms from the alteration of primary minerals.

  5. The Siglo Veinte Mine, where paravauxite was first discovered, is one of the world's largest tin mines. This highlights the mineral's connection to tin deposits.

Uses and Applications

While paravauxite is not widely used in commercial applications, it holds value in other areas. Let's look at some of its uses.

  1. Paravauxite is primarily a collector's mineral. Its rarity and unique properties make it highly sought after by mineral collectors.

  2. The mineral is used in geological research. Studying paravauxite can provide insights into hydrothermal processes and phosphate mineralogy.

  3. Paravauxite specimens are often displayed in museums. These exhibits help educate the public about rare minerals.

  4. The mineral can be used in educational settings. It serves as a teaching tool for geology students learning about mineral identification and classification.

  5. Paravauxite's unique properties make it a subject of scientific studies. Researchers investigate its formation, structure, and associations with other minerals.
