    • What is limestone?

      2021-3-26 · Limestone is an organic, sedimentary rock. This means it was formed from the remains of tiny shells and micro-skeletons deposited on the sea bed. Over the years this sediment was compressed to form solid rock. Limestone is formed in layers – called bedding planes. These bedding planes contain vertical cracks called joints.

    • Sediments and Sedimentary Rocks

      Furthermore, despite their great variety, only three sedimentary rocks are very common - shale, sandstone, and limestone. Sedimentary rocks contain numerous clues to their origin and the environment in which they were deposited. Geologists determine this information from the shape and sequence of rock layers and from the sediment grains and the ...
