  1. Sedimentary Rocks Compaction and Cementation of

    Sedimentary rocks like shale limestone and sandstone form from preexisting rocks. If you start with sand mud or organic material these sediment deposits get eroded and transported over time. This happens because shorelines move back and forth compacting material below like a steam roller.

    Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth’s sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate cement lime and building stone are made. 71% of all crushed stone produced in the is either limestone or dolomite.
