Pullfrey and Walsh provide a concise survey of the geology and mineral resources of Kenya, outlining the principal geological formations and relating them to the country’s known mineral deposits. The account covers the Precambrian basement rocks, younger sedimentary formations, and Tertiary and Quaternary volcanic rocks, together with economically important metallic and non-metallic minerals. Gem materials and ornamental stones are included among the mineral resources, placing their occurrences within the broader geological framework of Kenya. The work serves as a compact introduction to the country’s economic geology and to the relationship between its geological history and mineral resources.
