Examples of common chemical sedimentary rocks include halite, which  is rock salt; coal, and limestone.These sedimentary rocks are  formed from sediment produced by chemica â¦ l weathering.imestone or Sandstone are two examples of sedimentary rocks. Two examples of sedimentary rocks are slate (fine silt) and chalk (shell remains of sea creatures).
