| Because of the young age of metamorphism and the low radiogenic Pb content of the titanite, precise geochronometric information was not obtained. |
|
| The pegmatites are composed of K-feldspar, quartz, plagioclase and biotite, with titanite, opaque minerals and apatite as accessory minerals. |
|
| Large titanite euhedra are abundant along with apatite and zircon, with allanite and epidote less so. |
|
| Small well-developed brown anatase crystals replacing larger titanite crystals have been collected from Corral Canyon, Churchill County, Nevada. |
|
| The sample is composed of K-feldspar, plagioclase and quartz with accessory apatite, magnetite, titanite, zircon and secondary epidote. |
|
| Secondary titanite, chlorite, white mica and pyrrhotite are abundant, and some samples contain metamorphic biotite. |
|
| All four samples are medium-grained, and comprise variable proportions of hornblende, feldspar and quartz with accessory biotite and titanite. |
|
| Growth of titanite took place during the metamorphic climax in rocks from the kyanite and sillimanite zones. |
|
| The metabasites typically contain coarse-grained hornblende, biotite and plagioclase with accessory titanite. |
|
| In several cases it is possible to test this by comparing early and late varieties of titanite from the same sample or same locality. |
|
| The matrix is dominantly felsic, but also contains biotite, muscovite, epidote and titanite. |
|
| Magnetite, apatite, titanite and zircon make up the accessory minerals. |
|
| Accessory chlorite, magnetite or ilmenite, titanite, apatite, partly chloritized biotite, epidote, pyrite and sometimes cummingtonite, are present. |
|
| How about sphene versus titanite, or celestine versus celestite? |
|
| The greenschist-facies overprint resulted in the growth of actinolitic amphiboles, plagioclase and titanite at the expense of pyroxene and rutile or ilmenite. |
|
| One of my favorite gems is sphene, or more properly, titanite. |
|
| The titanite grains from Zones 1 and 2 show marginal growth interstitial to newly grown crystals of metamorphic minerals such as plagioclase, biotite and zoisite. |
|
| Some calcareous veins contain epidote, titanite and apatite. |
|
| Brookite is best known from alpine-cleft-type occurrences, where it is round with anatase, rutile, titanite, quartz, adularia, albite, hematite, calcite, and chlorite. |
|
| As the magma cools, REE elements eventually become concentrated in accessory phases such as zircon, rutile, ilmenite, titanite and monazite. |
|
|
|
| Zircon, opaque minerals, titanite and Fe oxides are present in the rock as accessory minerals. |
|
| Typical accessory minerals include apatite, zircon, fluorite, magnetite, titanite, and allanite. |
|
| Kyanite, garnet, monazite, and amphibole are common minerals, while apatite, anatase, titanite, corundum, pyroxene, and epidote are rare. |
|
| The mylonitic foliation, which is defined by biotite, quartz, titanite and epidote, is deflected around the porphyroclasts. |
|
| In addition, the clay minerals included common mica, occasional garnet group minerals, apatite, and rare titanite, ilmenite, zircon, rutile and iron oxides. |
|
| Titanite occurs as up to 2 cm long, dark brown, euhedral crystals in textural equilibrium with the other minerals. |
