The black colors are likely two or three different minerals. If magma cools slowly, deep within the crust, the resulting rock is called intrusive or plutonic.Sedimentary rocks are rocks formed by deposition from a fluid (i.e., water, air, or ice). They are classified on the basis of their texture, grain size, and mineralogic composition. Characteristics of sedimentary rocks are described in Pellant p. 38-41and 44-45; Marshak, p. 176-186. Texture: Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.A number of classification schemes have been proposed to further subdivide conglomerates and breccias. One scheme is purely descriptive, partitioning these coarse clastic sedimentary rocks on the basis of grain size (e.g., boulder breccia versus cobble conglomerate) or composition or both (chert pebble breccia versus limestone cobble conglomerate).39.5% of the average surface sedimentary composition on P.

Oil Shale is organic-rich sedimentary rocks that have contain kerogen (insoluble organic matter in sedimentary rock. When subjected to intense heat, these shales yield oil. Oil shales range from brown to black in color. They are flammable and burn with a sooty flame. To identify a sedimentary rock, first determine if it is clastic, organic, or chemical. If it is clastic, examine the sizes and shapes of the fragments to determine the rock type. If it is organic or chemical, determine the rock’s composition and look for unique characteristics to arrive at an identification.Conglomerate is a clastic sedimentary rock made up of rounded clasts that are greater than two millimeters in diameter. The spaces between the clasts are generally filled with sand- and clay-size particles. The rock is bound together by a cement that is usually composed of calcite or quartz. Composition describes the mineral components found in sediment or sedimentary rock and may be influenced by local geology, like source rock and hydrology. Other than clay, most sediment components are easily determined by visual inspection (see Chapter 3 , Minerals). Dolomite is a common rock-forming mineral.
