layering
Metamorphic rocks have been modified by heat, pressure and chemical process usually while buried deep below Earth's surface. Exposure to these extreme conditions has altered the mineralogy, texture and chemical composition of the rocks. There are two basic types of metamorphic rocks: 1) foliated metamorphic rocks such as gneiss, phyllite, schist and slate which have a layered or banded appearance that is produced by exposure to heat and directed pressure; and, 2) non-foliated metamorphic rocks such as marble and quartzite which do not have a layered or banded appearance. Pictures and brief descriptions of some common types of metamorphic rocks are provided below.
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.
They are called sedimentary rocks.

Many people think that the wasl should be banded because it dosent prove to help anyone in their learning

There are at least that many nearly-indistinguishable banded species in the genus Amegilla, but the "true" Australian blue banded bee is Amegilla cingulata. The species found in SE Asia is Amegilla zonata.
