planjalite

Planjalite is a rare mineral classified as a phosphate mineral, known for its distinctive composition and occurrence. It belongs to the apatite group of minerals and typically forms in hydrothermal and pegmatitic environments. The mineral was first described in the early 21st century, with its name derived from its geographical origin or specific mineralogical features, depending on the initial discovery source.

Chemically, planjalite is characterized by a phosphate structure that may include elements such as calcium, fluorine, chlorine, and hydroxide ions, contributing to its unique properties. Its crystalline structure often manifests in tabular or prismatic forms, with a vitreous luster and a variable coloration ranging from pale yellow to greenish hues.

Planjalite's physical properties include a relatively high hardness on the Mohs scale, typically around 4 to 5, and a conchoidal fracture. Its transparency can vary from transparent to translucent, making it of interest to mineral collectors and researchers studying phosphate mineralogy.

This mineral occurs in specific geological settings, often associated with other phosphate minerals, secondary mineral deposits, and pegmatitic rocks. Because of its rarity, genuine specimens of planjalite are relatively scarce and are primarily found in select mineralogical localities.

Research into planjalite contributes to understanding phosphate mineral deposits and their potential applications, including in fields like geology and material sciences. Due to its rarity and specific occurrence, planjalite remains primarily of interest to mineralogists and collectors rather than industrial use.
