Yes, silicate minerals can form non-foliated metamorphic rocks. Non-foliated metamorphic rocks, such as marble and quartzite, are typically composed of silicate minerals and do not exhibit a layered or banded appearance. Instead, they have a more uniform texture due to the recrystallization of minerals under heat and pressure. While not all silicate minerals result in non-foliated rocks, many do when subjected to specific metamorphic conditions.
Quartzite
Lack of banding
Quartzite is a nonfoliated metamorphic rock that is granular and composed mainly of quartz. It forms from the metamorphism of quartz-rich sandstone.
Nonfoliated metamorphic rocks are formed around igneous intrusions where the temperatures are high but the pressures are relatively low and equal in all directions (confining pressure).
