  4. The mineral is often found in association with other uranium minerals. This includes autunite, torbernite, and uranophane.

  5. Coconinoite has a yellow to greenish-yellow color. This coloration is due to the presence of uranium.

Physical Properties of Coconinoite

Understanding the physical properties of Coconinoite can help in identifying and studying this mineral.

  1. Coconinoite has a monoclinic crystal system. This means its crystal structure is shaped like a skewed rectangle.

  2. The mineral has a vitreous to silky luster. This gives it a shiny appearance when light reflects off its surface.

  3. Coconinoite is relatively soft, with a Mohs hardness of about 2.5. This makes it easy to scratch with a fingernail.

  4. The mineral is translucent to transparent. Light can pass through it, making it appear somewhat see-through.

  5. Coconinoite has a specific gravity of 3.1 to 3.2. This measures its density compared to water.

Chemical Composition of Coconinoite

The chemical makeup of Coconinoite is what makes it unique and interesting to scientists.

  1. Coconinoite's chemical formula is (UO2)3(PO4)2·12H2O. This indicates it contains uranium, phosphate, and water molecules.

  2. The mineral is radioactive due to its uranium content. Handling it requires caution and proper safety measures.

  3. Coconinoite can decompose in water over time. This is because it contains water in its structure.

  4. The mineral can also alter to other uranium minerals. This happens under certain environmental conditions.

  5. Coconinoite is soluble in acids. This means it can dissolve when exposed to acidic solutions.
