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

• Evaporite sedimentary rocks are composed of minerals formed from the evaporation of water. The most common evaporite minerals are carbonates (calcite and others based on CO2−3), chlorides (halite and others built on Cl−), and sulfates (gypsum and others built on SO2− 4). Evaporite rocks commonly include abundant halite (rock salt), gypsum, and anhydrite.
• Organic-rich sedimentary rocks have significant amounts of organic material, generally in excess of 5% total organic carbon. Common examples include coal, oil shale, and other sedimentary rocks that act as reservoirs for liquid hydrocarbons and natural gas.
• Siliceous sedimentary rocks are almost entirely composed of silica (SiO2), typically as chert, opal, chalcedony or other microcrystalline forms.
• Iron-rich sedimentary rocks are composed of >15% iron; the most common forms are banded iron formations and ironstones
