How Do You Spell PARAVINOGRADOVITE?

Pronunciation: [pˈaɹəvˌɪnəɡɹˌadəvˌa͡ɪt] (IPA)

Paravinogradovite is a rare mineral named after Russian geologist Alexei Petrovich Vinogradov. The name is pronounced /pærævɪˈnoʊɡrədaɪt/ and is spelled with a combination of letters that represent the sounds in the word. The "p" is pronounced "p", the "a" is pronounced like "a" in "cat", the "r" is pronounced with a slight roll of the tongue, the "v" is pronounced "v", and so on. The IPA phonetic transcription helps us understand the pronunciation of this long and tricky word.

PARAVINOGRADOVITE Meaning and Definition

  1. Paravinogradovite is a rare mineral that belongs to the tellurite mineral group and has the chemical formula PbSnMo6+Te2O12. It was first discovered in the Paratunka deposit on the Kamchatka Peninsula in Russia, hence its name.

    Paravinogradovite typically occurs as small, tabular, or prismatic crystals that are often elongated along the c-axis. It has a vitreous to adamantine luster and can exhibit various shades of brown, ranging from light yellowish-brown to dark reddish-brown. The mineral is translucent to transparent, with a non-fluorescent property.

    In terms of its crystal structure, paravinogradovite crystallizes in the monoclinic system and belongs to the space group P2₁/a. It consists of layers of molybdenum-oxygen polyhedra and tellurium-oxygen polyhedra, with lead and tin atoms occupying the interlayer sites. The overall structure of paravinogradovite exhibits a tunnel-like arrangement, providing spaces for smaller cations such as potassium and sodium.

    Paravinogradovite is primarily found in hydrothermal veins associated with molybdenum and tellurium minerals. It forms through the alteration of primary tellurides and selenides in oxidizing environments.

    Due to its rarity and limited occurrence, paravinogradovite does not hold any significant industrial or commercial uses. However, its unique crystal structure and chemical composition make it a subject of interest for mineralogists and researchers studying tellurite minerals and their crystallography.

Etymology of PARAVINOGRADOVITE

The word "paravinogradovite" is a mineral name derived from the name of the Russian mineralogist Vladimir Alexandrovich Vinogradov. The "para" prefix is typically used to indicate that it is a polymorph or a related mineral, while "vinogradovite" is derived from Vinogradov's last name. The name "paravinogradovite" was proposed in honor of Vinogradov's significant contributions to the field of mineralogy.
