Young Blonde Girl With Blue Eyes Takes Off Her Bra Near Sedimentary Rocks At The Sea Coast

Compositional classification schemes
Alternatively, sedimentary rocks can be subdivided into compositional groups based on their mineralogy:
• Siliciclastic sedimentary rocks, are dominantly composed of silicate minerals. The sediment that makes up these rocks was transported as bed load, suspended load, or by sediment gravity flows. Siliciclastic sedimentary rocks are subdivided into conglomerates and breccias, sandstone, and mudrocks.
• Carbonate sedimentary rocks are composed of calcite (rhombohedral CaCO3), aragonite (orthorhombic CaCO3), dolomite (CaMg(CO3)2), and other carbonate minerals based on the CO2−3 ion. Common examples include limestone and dolostone.
