Accessory Minerals in New Idria serpentinite
, 2019 Serpentinite is a rock composed almost wholly of serpentine-group minerals and contain accessory minerals that are sensitive to formation chemical condition. In 2017 Patton did a study on accessory minerals of an ophiolite.

Accessory minerals: a provenancing tool for steatite quarries [PDF]
ArchaeometryAbstract Steatite has been a widely traded material across a range of archaeological contexts. Yet, challenges inherent to determining its provenance limits our understanding of the networks and mechanisms of its exchange. We present a robust new accessory mineral provenancing “fingerprint” method based their specific growth history ...

Potential Occurrence of Accessory Minerals in the Lower Mantle
MineralsIn a seminal paper V.M. Goldschmidt pointed out that, in terms of volume of the constituent ions, Earth’s crust and mantle are basically a packing of negatively charged oxygen ions bound together by the volumetrically barely significant cations. Here, this statement is revisited using modern assessments of mantle composition and pressure-dependent ...
