Describe the formation of igneous, metamorphic, and sedimentary rocks. Igneous rocks form by melting and solidification Metamorphic rocks form by heat and pressure Sedimentary rocks form by compaction and cementation. The Guide to Getting it On How is a dike formed? A dike is formed when magma is injected into fractures in rock.By using radiometric dating to determine the age of igneous brackets, researchers can accurately determine the age of the sedimentary layers between them. Using the basic ideas of bracketing and radiometric dating, researchers have determined the age of rock layers all over the world. Radioisotope Dating of Rocks in Based on radiometric dating, long-age geologists say that the basalt dating” methods to successfully date Grand Canyon rocks.

The most widely known form of radiometric dating is carbon dating. This is what archaeologists use to determine the age of human-made artifacts. But carbon dating won't work on dinosaur bones. The half-life of carbon is only 5, years, so carbon dating is only effective on samples that are less than 50, years old.

According to the Smithsonian Institute, using radiodating of sedimentary rock tells the date of formation of the original igneous rock, which, through the processes of weathering and erosion, formed the layers of the sedimentary rock. Radiodating determines the maximum age of sedimentary rock. If a layer of igneous rock forms on top of the sedimentary rock, scientists determine an age bracket for the rock sample, but not an absolute age. Geological Survey states that it is possible to use Carbon radiometric dating for sedimentary rock younger than 50, years by dating once living material from the sediment.
