| They have parallel bright shiny mica wrapping round large grains of pink garnet, brown staurolite, or blue kyanite. |
|
| Initial monazite growth at staurolite facies conditions takes place during prograde conditions. |
|
| Wing et al. suggested that cordierite or staurolite could play the same role as andalusite or kyanite in a monazite-producing reaction. |
|
| The Stephens Creek Shear Zone contains a peak assemblage of garnet-plagioclase-staurolite-biotite, with staurolite overgrowing garnet. |
|
| This same rock is also the source for staurolite in Patrick County, Virginia. |
|
| The schist has been glaciated, resulting in exposed outcrop surfaces of 20-30 meters, studded with staurolite crystals. |
|
| The Burd Gol melange is also the most highly metamorphosed unit locally containing amphibolite grade staurolite and kyanite schists. |
|
| The sample contains the mineral assemblage garnet, staurolite, biotite and rare epidote. |
|
| Furthermore, the textural evidence implies that the main hydrous minerals in this rock, staurolite and biotite, largely predate garnet growth. |
|
| The petrological evolution of the shear zones indicates that either staurolite grew before garnet or, more commonly, garnet growth occurred before staurolite. |
|
| These phases predate the main foliation, a well-differentiated crenulation cleavage that wraps around the porphyroblasts of garnet and staurolite. |
|
| Textures of kyanite, xenotime and monazite, and some staurolite and biotite, indicate that peak metamorphic mineral growth occurred after D 2 deformation. |
|
| For example, Georgia's state rock is staurolite, and quartz crystal is the state gem. |
|
| The researchers identified a speck of the mineral staurolite in a South African diamond. |
|
| There are number of natural and synthetic materials which could be used in place of garnet for abrasive purposes such as staurolite, diamond and corundum among others. |
