Consequently, carbonates are ideal petroleum reservoirs.Sandstones with Carbonate Cement, Coal Exploration Core,Oct 02, 2019· Sandstones occasionally have carbonate mineral cements that cause the rock to react to HCl. Carbonate-cemented sandstones may have any of the sedimentary structures seen in other kinds of sandstone. Two kinds of carbonate cement are common in Carboniferous coal fields: (64X CaCO 3) Calcite-cemented sandstone (64X FeCO 3) Siderite-cemented sandstone

Sandstones make up about 20 to 25 percent of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface, as seen in the Goldich dissolution series.
