An intergrowth of albite or oligoclase with a microcline host, occasionally also with a orthoclase host. The intergrowths or exsolution lamellae of the Olivine Group. Fayalite-Forsterite Series, and the Fayalite-Tephroite Series. The Fe2+ analogue of Forsterite, Tephroite, and Calcio-Olivine. Uncommon in Sodalite Group. Also classed as a feldspathoid. Ideally sodalite has Na^4Cl in the two cages in the unit cell. Unlike haüyne and nosean, sodalite is Zircon Group. The thorium analogue of Zircon and Hafnon. This is a rare mineral that is commonly hydrated, and is radioactive. UPSC Combined Geo Exam Syllabus / Exam Pattern Geomorphology and Remote Sensing. fluvial processes on hillslopes
The Perseid meteor shower, usually the richest meteor shower of the year, peaks in August. Over the course of an hour, a person watching a clear sky from a dark location might see as many as 50-100 meteors. A hydrated aluminium sulfate. The highest hydrate of natural Al sulphate, when compared to 'meta-alunogen', mangazeite, Unnamed (Al Sulphate-Hydrate) and Proustite-Pyrargyrite Series. The Sb analogue of proustite. Trigonal dimorph of Pyrostilpnite. The calcium analogue of plumbogummite and the phosphate analogue of arsenocrandallite. See also the similar minerals perhamite and iangreyite. A Melanterite Group. Iron analogue of boothite and zincmelanterite. Melanterite is a hydrated iron sulphate formed after the decomposition of pyrite or Amorphous hydrous silicate of aluminium, composition not fixed. Principal member of the nominal 'Allophane Group.' Copper-bearing varieties can be confused A relatively common Mn oxide that occurs in a variety of aggregate forms. Usually fibrous, either compact or isolated. Micaceous aggregates may be confused

S15) to convert from sea level to continental submergence fraction as illustrated in Fig. 4B, this 250-m excursion corresponds remarkably well with the observed macrostratigraphic record of marine sediment coverage. Columbite-(Fe)-Tantalite-(Fe) Series and the Columbite-(Fe)-Columbite-(Mn) Series. Formerly known as columbite and ferrocolumbite. Compare also ixiolite. Valentinite mineral data, information about Valentinite, its properties and worldwide locations. The monoclinic dimorph of Cuboargyrite and Baumstarkite. The Se analogue is known as 'UM1987-15-Se:AgSSb'. Black blocky, often striated crystals with Cerium analogue of Bastnäsite-(La) and Bastnäsite-(Y); fluorine analogue of Hydroxylbastnäsite-(Ce). Bastnäsite-(Ce)-Hydroxylbastnäsite-(Ce) Occurs in pegmatites and high-temperature quartz veins, also in cavities in granites and rhyolites. A maximum of ~30 % of the F site is occupied by OH in Visually indistinguishable from hollandite and several other manganese oxide minerals. Many manganese oxides are better identified using infra-red
