What magma type has melted sedimentary rocks?

Magma that has melted sedimentary rocks is typically classified as sialic magma, which is rich in silica and aluminum. This type of magma often forms through the process of crustal anatexis, where heat and pressure cause sedimentary rocks to partially melt. The resulting magma can contribute to the formation of granitic rocks when it cools and solidifies. Sialic magma is generally less dense and more viscous than basaltic magma.
