Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks
From Greek phullon leaf + -ite1

Archaeological Significance
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

Learn more about Properties of Phyllite
What is Phyllite? In this section, we will learn more about properties of Phyllite i.e. physical and thermal properties. Physical properties of Phyllite include Color, Streak, Hardness, Structure, Cleavage, Fracture, Luster, Specific Gravity etc. The strength of Phyllite is 50.00 N/mm2. Streak of Phyllite is white while its cleavage is crenulation and pervasive. Luster of Phyllite is phyllitic and its fracture is conchoidal. Phyllite is opaque in nature.
