**Reederite-(Y)**
**Definition**
Reederite-(Y) is a rare uranium-bearing mineral characterized by its complex chemical composition and distinctive crystal structure. It is primarily noted for containing yttrium as a significant constituent.
## Overview
Reederite-(Y) belongs to the category of uranyl carbonate minerals and is recognized for its unique combination of elements, including uranium, yttrium, sodium, and carbonate groups. The mineral typically forms in oxidized zones of uranium deposits, where it crystallizes under specific geochemical conditions.
## Chemical Composition and Structure
The chemical formula of Reederite-(Y) reflects its complex nature, incorporating uranyl ions (UO₂)²⁺ coordinated with carbonate (CO₃)²⁻ groups and yttrium (Y) as a dominant rare earth element. Its crystal structure is notable for layered arrangements that influence its physical properties and stability.
## Occurrence and Formation
Reederite-(Y) is found in limited localities, often associated with other secondary uranium minerals. Its formation is linked to the alteration of primary uranium ores in the presence of carbonate-rich fluids, which facilitate the incorporation of yttrium and sodium into its structure.
## Significance
Due to its rarity and uranium content, Reederite-(Y) is of interest to mineralogists and geologists studying uranium mineralization and the geochemical behavior of rare earth elements in oxidizing environments.
**Meta Description**
Reederite-(Y) is a rare uranium-bearing mineral containing yttrium, found in oxidized uranium deposits. It is notable for its complex uranyl carbonate structure and geological significance.
