priderite
Priderite is a mineral species consisting of titanium and niobium oxides. Its chemical formula is (Ti,Nb)O2. It is typically found in igneous rocks, particularly those of alkaline affinity. Priderite is characterized by its tetragonal crystal system and is often found as small, prismatic crystals. Its color can range from black to reddish-brown. The mineral is relatively rare and has been documented in various locations worldwide, including Australia and Russia. It is named in honor of the Australian geologist and mineralogist Dr. H.T. Prider. Priderite's significance lies primarily in its mineralogical interest and its association with specific geological environments. It does not possess significant economic value as a commodity. Research into priderite continues to explore its formation processes and its role within complex mineral assemblages.
