Accessory mineral Britannica

Accessory mineral, any mineral in an igneous rock not essential to the naming of the rock.When it is present in small amounts, as is common, it is called a minor accessory. If the amount is greater or is of special significance, the mineral is called a varietal, or characterizing, accessory and may give a varietal name to the rock (e.g., the mineral biotite in biotite granite).

Accessory minerals in igneous and metamorphic rocks

This issue is devoted to papers on accessory minerals contributed to the Accessory Minerals Session at the 20th General Meeting of the International Mineralogical Association held in Budapest 2127 August 2010. The themes included in this special issue not only cover many aspects of the mineralogy and crystal chemistry of zircon, monazite, magnetite, beryl, sphene, columbite, and NbTa

Accessory Mineral an overview ScienceDirect Topics

Each accessory mineral is stabilized in a rock via a single element or suite of related elements, specifically phosphorous (apatite), REE (allanite, monazite, xenotime), zirconium (zircon), and titanium (titanite). Trace elements also occur in the major minerals

Identifying Accessory Mineral Saturation during

INTRODUCTION. Accessory minerals typically compose less than one modal percent of a wholerock sample, yet host significant fractions of the wholerock budget of important trace elements and isotopes (Gromet Silver, 1983 Bea, 1996 Vervoot et al., 1996).One mineral in particular, zircon, has become an invaluable stopoff point on the journey of investigation into crustal evolution

Accessory Mineral Chemistry of High BaSr Granites

Although the wholerock chemistry (trace element, radiogenic and stable isotopes) of the Rogart and Strontian plutons is well constrained (Fowler et al., 2001, 2008), studies of accessory minerals in other intrusions have demonstrated that these can give additional information on petrogenesis (e.g. Sha Chappell, 1999 Hoskin et al., 2000

Basalt Rock Formation, Properties, Composition, Uses

Accessory minerals present in relatively minor amounts include iron oxides and irontitanium oxides, such as magnetite, ulvospinel, and ilmenite. Because of the presence of such oxide minerals, basalt can acquire strong magnetic signatures as it cools, and paleomagnetic studies have
