: ilmenite, epidote, zircon and apatite occupy a small fraction of the volume.
The abundance of accessory minerals
is 1-3% and opaque minerals is 1-3%.
The RM mineralogy, as shown by X-ray diffractometry, was dominated by plagioclases and pyroxens with ilmenite, magnetite, apatite and quartz as accessory minerals
Epidote, quartz, muscovite, H/L and clay were accessory minerals
.The complete characterization of the originally employed historic materials also provided information on the techniques, which should be respected for successful restoration programs.
The dominant minerals are plagioclase phenocrysts, quartz, K-feldspar, and hornblende and accessory minerals
such as biotite, pyroxene, apatite, sphene, and opaque minerals can be seen in some of these rocks.
In accordance with these observations, a variable proportion of interstitial minerals, including clinopyroxene, [H.sub.2]O-bearing phases (amphibole, phlogopite) and other accessory minerals
In this paper, accessory minerals
such as zircon, sphene and apatite are studied in Ghareh Gheshlagh area.
A variety of accessory minerals
, including biotite, muscovite, sphene, zircon, garnet, and epidote, also occur in these rocks.
Rare earth elements in ultramafic and mafic rocks and their minerals; minor and accessory minerals
The groundmass is composed of quartz, feldspar, devitrified glass, minor magnetite, ilmenite, pyrite, rare galena, fluorite and accessory minerals
similar to those in trachyte samples (i.e., microlites of zircon, apatite, monazite, and allanite).
