Sandstone/limestone flaake graphite

Virtual Museum ID: 19-NCM17

Specimen Summary

Limestone is a carbonate sedimentary rock. It is composed of skeletal fragments of organisms found in marine areas such as corals and molluscs. It consists primarily of calcite, which reacts to hydrochloric acid. Limestone can be found in warm and shallow marine waters. There are varieties of limestone such as chalk, coquina, tufa and more.

Sandstone is a sedimentary rock that is composed of sand sized particles of rocks, minerals, and organic material. Sand-size particles range in size from 1/16 millimeter to 2 millimeters. It has a cementing material that binds the sand particles together and can contain a matrix made of silt or clay. It is one of the more common sedimentary rocks. These rocks can be found in sedimentary basins. Sandstone is used as a construction material or a material used in manufacturing. It is also an aquifer for groundwater.
