St. Croix County is underlain by Cambrian and Ordovician sedimentary rocks. The Cambrian sediments are largely sandstones, often glauconitic. The Ordovician section tends to be carbonate dominated, with the notable exception of the super-mature St. Peter Sandstone. The carbonates are quarried for crushed stone. Calcite and drusy quartz can be found in these rocks.

Several faults originally of Keweenawan age, but reactived in post-Ordovician time, shift Cambrian and Ordovician strata. The most notable is the Hastings - Hudson Fault, traceable near Hudson and through Willow River State Park.

The Wisconsinan St. Croix moraine cuts through the county near the Interstate 94 corridor. The landscape south of there is bedrock dominated with only thin older glacial drift. North of the interstate the terrain is dominated by glacial landforms. Interesting materials can be found in the glacial drift including iron formation, float copper, omars, jasper and "Lake Superior" agates.
