Granite and quartzite are sillious rock.
Slate and laterite rock are argillaceous rock.
Marble and limestone are calcareous rock.
These are all chemical classifications of rock.

It's Both metamorphic and silicious rock.

It is not a sillicious rock. Silicious rocks are sedimentary rocks. Quartzite is a metamorphic rock.
So, option A is correct.

It is metamorphic & silicious rock.

But silicious rock is the type of metamorphic rock.

So, silicious rock is the correct answer.

You are absolutely right, Thanks @Amol Dabke.

Geological classification of quartzite is a metamorphic rock because it formed metamorphic action on sandstone.

Chemical classification is silicious rock. It is a non-stratified rock.

Agree.

It is Physically Metamorphic and Chemically Silicious.
Adarsh said:   7 years ago
From geological classification, Quartzite is metamorphic rock and physical classification Quartzite is stratified and chemical classification Quartzite is silicious rock.

Quartzite is a nonfoliated metamorphic rock composed almost entirely of quartz. It usually forms from the metamorphism of sandstone.
