As an AI language model, I do not have access to recent geographical data on the topic. However, I can provide general information about the formation and distribution of rocks. The rocks found in a particular region are influenced by several factors such as geological history, tectonic activity, and environmental conditions. The rocks in Northern and Central Minnesota are predominantly formed by the Canadian Shield, a geological formation that is more than 3 billion years old. These rocks are typically igneous and metamorphic rocks, such as granites, gneisses, and schists. The rocks in Southern Minnesota, including South Saint Paul, are primarily sedimentary rocks, such as sandstone, limestone, and shale. These sedimentary rocks are formed by the deposition of sediments in shallow seas, lakes, or rivers over millions of years. Therefore, the rocks found in South Saint Paul may not have a direct relationship with the rocks in Northern and Central Minnesota, although regional geological processes may have contributed to their formation or distribution.
