Navajo Sandstone (NA-va-ho) 190 to 180 million years ago. The Navajo Formation consists of one rock layer, Navajo Sandstone. While the Navajo is a dominant rock layer across the Colorado Plateau, it is thickest in Zion National Park - 2200 feet (700 m) thick. Navajo is a cliff-forming sandstone, but soft and easily cut by flowing water.The monolith is within Uluru–Kata Tjuta National Park (established in 1958 as Ayers Rock–Mount Olga National Park and renamed in 1993), which also includes the Olgas (Kata Tjuta), a group of tors about 20 miles (32 km) west-northwest of Uluru/Ayers Rock. The park has an area of 512 square miles (1,326 square km). In 1985 official ownership …only. The sedimentary sandstone equivalent is termed a "quartz cemented quartzose sandstone." Samples submitted to a petrographic laboratory should be representative of the in-place rock unit. For example, if a granitic gneiss is sampled but only the granite portion submitted, the rock will be petrographically classified as Sedimentary rock - Clastic, Chemical, Organic: There are many different systems of classifying sandstones, but the most commonly used schemes incorporate both texture (the presence and amount of either interstitial matrix—i.e., clasts with diameters finer than 0.03 millimetre—or chemical cement) and mineralogy (the relative amount of quartz and the …

It forms from the slow crystallization of magma below Earth's surface. Granite is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles, and other minerals. This mineral composition usually gives granite a red, pink, gray ...Description. Conglomerate is a sedimentary rock made of rounded pebbles and sand that is usually held together (cemented) by silica, calcite or iron oxide. It is a stone similar to sandstone but the rock particles are rounded or angular gravel rather than sand. Conglomerate is a coarse-grained rock that is often formed in riverbeds.
