Many of these organisms have left their remains as fossils in sedimentary rocks.Geologists have studied the order in which fossils appeared and disappeared through time and rocks. Fossils can help to match rocks of the same age, even when you find those rocks a long way apart.These provide us with an abundance of resources, which we use to worship and serve Him for His purposes and glory.Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample.They point to a catastrophic origin for granites, consistent with the biblical timeframe for earth history and God’s judgment during the Flood.
In the walls of the Grand Canyon, we can see that the whole horizontal sedimentary strata sequence was folded without fracturing.
For example, microscopic dinoflagellates have been studied and dated in great detail around the world.
Correlation with them has helped geologists date many New Zealand rocks, including those containing dinosaurs.
Fossils are important for working out the relative ages of sedimentary rocks.
Throughout the history of life, different organisms have appeared, flourished and become extinct.Correlation can involve matching an undated rock with a dated one at another location.
