Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock. Coal is a sedimentary rock formed over millions of years from compressed plants. Sedimentary rock cannot be radiometrically dated you would only be dating the clasts themselves not the rock unit. The boundary between the two different rock types represents a n.

Objects enclosed in rock must be older than the time of rock formation the principle of inclusions the determination that a granite pluton is not intrusive into overlying sedimentary layers because there are pebbles of granite in the bottom most layer is an application of the principle of.

Inorganic detrital rocks on the other hand are formed from broken up pieces of other rocks not from living things. At the inner gorge of the grand canyon the vishnu schist and zoroaster granite are overlain by sedimentary rocks. It might be possible to date some chemical sedimentary rocks isotopically but there are no useful isotopes that can be used on old chemical sedimentary rocks.

The basalt is a sill intruded into older sedimentary rock. States that during the formation of sedimentary rocks each layer is older than the one above and younger than the one below this statement reflects the relative age of sedimentary rocks. The granite is older if the sandstone contains pebbles of the granite. Sedimentary dikes or clastic dikes are vertical bodies of sedimentary rock that cut off other rock layers.

The sedimentary layers were deposited on a basaltic lava flow. Then later a new pluton cooled creating new granite that is younger than the sandstone. But you could have had an igneous rock millions of years ago that was weathered and eroded into sediments that then became the sandstone. Strictly speaking granite is an.

Radiocarbon dating can be used on sediments or sedimentary rocks that contain carbon but it cannot be used on materials older than about 60 ka. One of the best known clastic sedimentary rocks is sandstone. These rocks are often called clastic sedimentary rocks. Bed 2 is older than bed 4 but younger than bed 1.
