Titanite widely known as Sphene is a calcium titanium nesosilicate common mineral with the chemical formula CaTiSiO5 This mineral comes in yellowish green yellow brown gray blue pink orange and colorless to translucent twinned crystal forming wedge shaped with high dispersion and adamantine luster is called titanite
The hydrothermal alteration of a chevkinite group mineral to titanite has commonly been reported in natural sequences but this is the first record of the identification of a titanite like phase made on the basis of a structural analysis Chevkinite group minerals forming large and common up to vol% accessory phases in monzodiorites and
Uses of Tourmaline Tourmaline is a versatile gemstone with a wide range of uses across various industries Here are some of the common uses of tourmaline Jewelry Tourmaline is highly valued as a gemstone and is widely used in jewelry It is cut into various shapes including faceted gemstones cabochons beads and carved ornaments

Few people have heard of the mineral sphene also called titanite but it is nevertheless extremely widespread occurring in most common rocks It can be useful to the Earth scientist as it contains information on the timing temperature and pressure of formation of many common rocks It is also a source of titanium—and can sometimes be used

Syenite is a coarse grained plutonic intrusive igneous rock that primarily consists of the minerals feldspar typically orthoclase feldspar and often includes smaller amounts of other minerals such as hornblende mica or granite which is another common intrusive igneous rock syenite contains minimal to no dominant presence
Titanite gets its name from the titanium in its chemical makeup Gem quality material is known as sphene The crystals form as wedge shapes and twinning is common
The name "biotite" is used in the field and in entry level geology courses because these minerals generally cannot be distinguished without optical chemical or x ray Biotite is a rock forming mineral found in a wide range of crystalline igneous rocks such as granite diorite gabbro peridotite and also forms under metamorphic conditions when argillaceous rocks
Dongguashan is one of the largest porphyry skarn Cu Au deposits in eastern China and titanite is found in the ore system Five types of both magmatic and hydrothermal titanites are distinguished based on their textural and chemical characteristics Types 1 and 2 titanites are magmatic in origin whereas types 3 4 and 5 are hydrothermal Magmatic titanites
In this chapter an overview of the findings to date from laboratory measurements of diffusion of cations in the accessory mineral phases zircon monazite apatite titanite sphene and xenotime is presented These minerals differ widely from one another in structure and composition but share some common characteristics
The Titanite stone consists of a mineral of the silicate class belonging to the sub class nesosilicates Actually it is a silicate made up of calcium and titanium with some impurities of aluminum and iron Its name is due to the large chemical amounts of titanium it

Appearance Uses and History Titanite is a little confusingly named Prior to 1982 Sphene was the more commonly used name but in 1982 the International Mineral Association chose the name Titanite as the official name However Sphene is still a widely used name and is sometimes used to refer to gemstone quality Titanite
Anatase is one of the three primary mineral forms of titanium dioxide TiO2 the other two being rutile and brookite It is a tetragonal mineral and a polymorph of TiO2 meaning that it shares the same chemical composition with rutile but has a different crystal structure Anatase is named after the Greek word "anatasis " which means extension in
4 Titanite a calcium titanium silicate named for its titanium content occurs as translucent to transparent crystals typically forming as flattened wedge shaped crystals often twinned the use of sphene was discredited by the International Mineralogical Association Commission on New Minerals and Mineral Names CNMMN and titanite is the
