All sedimentary rocks are made of different components that have been transported and deposited on the earth's surface. Detrital and chemical rocks are the two sub-types of sedimentary rocks.Bedding Planes. Figure 5.4.1 5.4. 1: Horizontal strata in southern Utah. The most basic sedimentary structure is bedding planes, the planes that separate the layers or strata in sedimentary and some volcanic rocks. Visible in exposed outcroppings, each bedding plane indicates a change in sediment deposition conditions.On strike-slip faults the motion is typically only horizontal, or with a very small vertical component, and as discussed above the sense of motion can be right lateral (the far side moves to the right), as in Figures 12.12 and 12.13, or it can be left lateral (the far side moves to the left). Transform faults are strike-slip faults.Alabaster. Alabaster is a common name, not a geological name, for massive gypsum rock. It …The three types of rock are: igneous. metamorphic. sedimentary. Look through the slideshow to find out more about the three rock types. 1. Igneous rocks. Igneous rocks are formed from the cooling ...Sedimentary Rocks. Sedimentary rocks are made when sand, mud, and pebbles are laid down in layers. They are classified into three groups: Clastic, Biologic, and Chemical. These layers are packed under more and more layers as time goes by. Eventually, the layers will lithify and turn into rock. You can find these rocks in deserts, …Sediments of all sorts may be lithified to become rocks. Clastic material typically comprises quartz and clays; less commonly other minerals. Minerals produced by chemical precipitation include clays, carbonates, sulfates, halides, zeolites, and chert.
