Lacustrine soils are formed from sedimentary deposits in ancient lakes. These deposits are generally made up of fine-grained elements including silt, clay, and occasionally carbonates, which are usually well-sorted and have highly laminated bedding.
Locations and examples
Examples include:
- The Great Lakes region of North America, where historic lake basins have left excellent soil suitable for cultivation.
- Former lake locations included Lake Bonneville in Utah, which covered a large chunk of the western United States thousands of years ago.
