Accessory Minerals. Accessory minerals may be included in any rock you pick up, but unlike rockforming minerals, they are not a basic part of the rock. In other words, a rock must contain quartz, feldspar, and mica in order to be classified as granite. If the rock also happens to contain the mineral titanite, the rock is still granite and

Apatite is a ubiquitous accessory mineral relative to other Clbearing minerals, which makes it an excellent candidate for studying chlorinity of coexisting fluid on the basis of its Cl content. Another advantage of apatite is that the Cl content is a function of fluid compositions and PT conditions.

Albite is also a common accessory mineral to many rare and unusual minerals. The iridescent variety Peristerite sometimes exhibits an adularescent sheen. This produces an unusual form of Moonstone. Albite sometimes forms in association with the feldspar mineral Microcline in alternating patterns, and forms a feldspar rock known as Perthite.

Accessory minerals occur in small quantities in their host rocks and, generally, they represent less than 5% of the modal composition. They have been described in a great variety of rocks (sedimentary, magmatic, volcanic, metamorphic) and they may form in different geological environments. Although

Accessory minerals allanite, monazite and rutile from amphibolite facies rocks across the Barrovian sequence of the Central Alps (Switzerland) were investigated for composition and UThPb ages. The growth ages of these minerals record multiple stages of prograde and peak metamorphism, which are notoriously difficult to date at these relatively low temperatures.

The behaviour of Nd, U, Th and Pb isotopes in granitic rocks is usually controlled by accessory minerals. In this study an approach is adopted which uses the initial 143 Nd 144 Nd as a geochemical tracer together with highprecision U Th Pb geochronology for accessory phases and their respective whole rock. This combination of techniques is applied to zircon, allanite, sphene, apatite and
