The geology of the greater Arcadia area is dominated by greenstone lithologies of the Arcturus Formation of the Harare Greenstone Belt (HGB). These greenstones are encircled and intruded by a variable suite of granitic rocks, the oldest of which may have been intruded at a similar time with the youngest felsic volcanic rocks of the belt.
