  • How do you recognize limestone and marble? [USGS]

    Limestone forms when shells, sand, and mud are deposited at the bottom of oceans and lakes and over time solidify into rock Marble forms when sedimentary limestone is heated and squeezed by natural rockforming processes so that the grains recrystallize If you look closely at a limestone, you can usually see fossil fragments (for example
