{{#category_index:S|sedimentary rock}} A rock formed from sediment that has accumulated in layers, or a chemical rock formed by precipitation from solution, or an organic rock consisting of the remains of the secretions of plants or animals. Clastic rocks were transported from their source area as solid particles whereas chemical rocks were transported as ions in solution and then precipitated. Clastics are often rich in quartz and/or feldspar and the most prominent chemical rocks are carbonates, salts, and sulphates. See Figure L-7.
