Limestone. Limestone ( calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium.Shale can be fairly hard if it has a silica cement, making it closer to chert. Typically, it is soft and easily weathers back into clay. Shale may be hard to find except in road cuts, unless a harder stone on top of it protects it from erosion. When shale undergoes greater heat and pressure, it becomes the metamorphic rock slate.Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash. Clastic Sedimentary Rocks:... Limestone member of the South Bend Formation. The Little Kaw is the transgressive limestone of this new cyclothem and the Gretna Shale is the offshore unit.It is the most common non-siliciclastic ( sandstone and shale are common siliciclastic rocks) sedimentary rock.
