The document outlines common rocks, specifically focusing on igneous rocks, with a detailed description of Diorite, which is an intrusive igneous rock with a phaneritic texture. It highlights its intermediate composition and suitability for engineering projects due to its hardness and weather resistance. Other categories of rocks, such as sedimentary and metamorphic, are mentioned but not detailed.
