Wood county consists of complex and intriguing Precambrian rocks, overlain by Cambrian sedimentary rocks in turn overlain by Pleistocene and recent sediments. The Precambrian rocks consist of older gneisses, overlain by meta-volcanic and meta-sedimentary rock, intruded by several generations of granitic rocks. The meta-volcanic rocks include several ultramafic bodies that have been worked for talc on a small scale. The rocks represent an oceanic and island arc sequence caught between colliding continents during the 1.8 to 1.85 billion year old Penokean Orogeny. A younger sequence of lower metamorphic grade Proterozoic quartzite, chert and argillaceous rocks is found as isolated mounds, most notable Powers Bluff County Park. Complex metamorphic rocks are also well exposed along the Wisconsin River at Wisconsin River.
