'''Monzogranit''' adalah [[batuan]] [[granit]] [[Biotit|ber-biotit]] yang dianggap sebagai hasil dari [[fraksionasi]] akhir [[magma]] (SiO2 > 73%, dan FeO + MgO + TiO2 < 2.4), bersifat [[Peraluminous|peraluminus]] rendah (Al2O3/ (CaO + Na2O + K2O) = 0.98–1.11),dan mengandung [[ilmenit]], [[sfen]], [[apatit]], dan [[zirkon]] sebagai mineral-mineral asesoris. Meskipun rentang komposisi monzogranit sangat kecil, batuan ini memilki kecenderungan yang dikontrol terutama oleh [[Kristalisasi fraksional|fraksionasi]] [[biotit]] dan [[plagioklas]]. (Fagiono,2002). Monzogranit dibagi menjadi dua kelompok (Monzogranit magnesio-potasik dan monzogranit fero-potasik) dan dikategorikan lebih jauh menjadi tipe-tipe batuan berdasaran karakteristik makroskopiknya, karateristik kelelehannya, fitur-fitur spesifik, ketersediaan data isotop, dan tempat khas keterbentukannya.
