Home Chronostratigraphic Earth History Geology. Evidence from radiometric dating indicates that Earth is about 4. Different spans of time on the GTS are usually delimited by changes in the composition of strata which correspond to them, indicating major geological or paleontological events, such as mass extinctions. For example , the boundary between the Cretaceous period and the Paleogene period is defined by the Cretaceous-Paleogene extinction event, which marked the demise of the non-avian dinosaurs and many other groups of life. Older time spans which predate the reliable fossil record before the Proterozoic Eon are defined by the absolute age. The first serious attempts to formulate a geological time scale that could be applied anywhere on Earth were made in the late 18th century. Share to:.
Radiometric dating of granitic intrusions associated with the Caledonian orogeny yields ages between about million and million years. The igneous activity that produced such intrusions constituted the final stages of subduction and obduction that is, overthrusting of the edge of one lithospheric plate.

As a result of this and other findings, notably that of Ernest Rutherford see. The ability to quantify the geologic time scale-i. As explained earlier. Radioisotope dating techniques have shown that this water is many thousands of years old. The use of such water, which is not being recharged under the current climatic regime, is termed groundwater mining. Mass spectrometers capable of measuring isotopic ratios allow the composition of elements to be determined in which one or more.
How Carbon Dating Works
During the s and s, isotopic dating of rocks showed that the crystalline massifs of Precambrian age from about 4. It is now evident.
Radiometric dating (often called radioactive dating) is a way to find out how old something is. The method compares the amount of a naturally occurring radioactive isotope and its decay products, in samples. The method uses known decay rates.
