Nambulite
Nambulite is a lithium bearing manganese silicate mineral with the chemical formula . It is named after the mineralogist, Matsuo Nambu (born 1917) of Tohoko University, Japan, who is known for his research in manganese minerals. The mineral was first discovered in the Funakozawa Mine of northeastern Japan, a metasedimentary manganese ore. Nambulite is formed from the reaction between a hydrothermal solution and rhodonite, and commonly creates veins in the host rock. Other than a collector's gem, however, it has little economic value. It belongs to the triclinic-pinacoidal crystal system (or triclinic-normal), meaning that it has three axes of unequal length (a, b, c), all intersecting at oblique angles with each other (none of the angles are equal to 90°). It belongs to the crystal class , meaning that any point on the crystal that is rotated 360° and then completely inverted will meet with an equal (but opposite) point on the crystal (see centrosymmetry). Its space group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naldrettite
Naldrettite is a mineral with a chemical formula of Pd2Sb. It is named after Anthony J. Naldrett (born 1933), a professor at the University of Toronto, who has made significant contributions to the International Mineralogical Association (IMA). Naldrettite is a new intermetallic mineral from the Mesamax Northwest deposit, Ungava region, Québec, Canada. Mineralization takes place around the base of basaltic dyke margins. Naldrettite is economically important because of its chemical composition (Pd2Sb). The sample in which the new mineral was discovered had high platinum group elements (PGEs) with palladium enrichment. Naldrettite occurs as anhedral grains that are commonly attached to sulfide minerals and are associated with clinochlore. It belongs to the orthorhombic In crystallography, the orthorhombic crystal system is one of the 7 crystal systems. Orthorhombic lattices result from stretching a cubic lattice along two of its orthogonal pairs by two different factors, resulti ...
