Wing et al. suggested that cordierite or staurolite could play the same role as andalusite or kyanite in a monazite-producing reaction. |
|
The foliation in the lowest unit is locally overgrown by porphyroblasts of andalusite and by biotite. |
|
The aluminium silicate minerals andalusite, kyanite, and sillimanite are good examples of this phenomenon of polymorphism. |
|
Monazite clusters occur in a variety of host minerals, including cordierite, quartz, biotite and andalusite. |
|
In sample IK99-31 chloritoid is in equilibrium with kyanite, andalusite and chlorite. |
|
The spotted textures are marked by the growth of biotite, cordierite and andalusite on the metamorphic foliation. |
|
Andalusite porphyroblasts that overgrow the S 1 fabric were pseudomorphed by colourless mica. |
|
These have a narrow metamorphic aureole in which andalusite is developed. |
|
Evidence of contact metamorphism of the wall-rock includes andalusite porphyroblasts enclosed in a fabric related to Caledonian nappe emplacement. |
