Limestone geology.
Common Minnesota Rocks. Throughout geologic time, Minnesota's landscape has undergone many changes. At times, high mountains lined the horizon. Later, vast seas engulfed the region. Still later, great sheets of ice covered the land. All of these environments are recorded in the rocks and sediments found around the state.

Geological vs. Commercial Definition of Limestone: There is an academic, geological definition and a practical, commercial definition of limestone. The geological definition of limestone is a sedimentary rock consisting of at least 50% calcite and dolomite, with less than 50% other rock materials.Next in the geologic column is the 200-foot (60 m)-thick Toroweap Formation (see 6c in figure 1). It consists of red and yellow sandstone and shaly gray limestone interbedded with gypsum. The formation was deposited in a warm, shallow sea as the shoreline transgressed (invaded) and regressed (retreated) over the land.While limestone itself doesn’t affect the environment, limestone mining can have a negative impact. On the other hand, the environment can affect limestone by breaking it down. Limestone mining can pollute water and create sinkholes.
The geology of Minnesota comprises the rock, minerals, and soils of the U.S. state of Minnesota, including their formation, development, distribution, and condition.
