Sedimentary rocks. and metamorphic rocks made form sedimentary rocks.
Metamorphic rocks can have various types of minerals, such as quartz, feldspar, mica, and amphibole, which form grains within the rock. These grains can be elongated or flattened, depending on the degree of metamorphism the rock has undergone. The size, shape, and alignment of these grains provide valuable information about the rock's history and the conditions under which it formed.
Metamorphic rocks are made from pre-existing rocks that have been altered by heat, pressure, and/or chemical processes within the Earth's crust. These changes cause the minerals and textures of the original rock to recrystallize, forming a new rock with different properties.
Understand that metamorphic rocks are those that have changed in some way by heat or pressure or both. Sedimentary rocks are formed from sediments and igneous rocks are formed by fire. When these rocks change again, they become metamorphic. Marble is one type of metamorphic rock.Look at the way the grain are formed. In schist rocks, you can see that the layers and the grains all go the same way. Warning Metamorphic rocks are difficult to classify because different amounts of heat or pressure to the same rock can look different.

Igneous rocks, Sedimentary rocks Metamorphic rocks.
Those would be non-foliated metamorphic rocks, like quartzite and marble.

It is a type of Metamorphic rock
Any type of rock can become metamorphic.
igneous, sedimentary. and metamorphic
Metamorphic is a group of rocks with similar characteristics. There are minerals in the rocks so they could be considered made of minerals but they are not minerals themselves.
Sediment rocks
Non-foliated metamorphic rock, such as marble or quartzite, is characterized by the absence of visible layering or banding. The mineral grains in these rocks recrystallize and grow in a uniform manner, without forming distinct layers like in foliated rocks. This type of metamorphism typically occurs under conditions of high pressure and temperature without the presence of directed stress.
