Geochronology - Wikipedia
网页Geochronology is the science of determining the age of rocks, fossils, and sediments using signatures inherent in the rocks themselves. Absolute geochronology can be accomplished through radioactive isotopes, whereas relative geochronology is provided by tools such as paleomagnetism and stable isotope ratios.
Geochronology | Definition, History, Dating, Importance, & Facts
网页Geochronology, field of scientific investigation concerned with determining the age and history of Earth’s rocks and rock assemblages. Such time determinations are made and the record of past geologic events is deciphered by studying the distribution and succession of rock strata, as well as the.

Geochronology - an overview | ScienceDirect Topics
网页Geochronology is the science of age dating earth materials (rocks, minerals, fossils) and geologic events (Fig. 2). It plays a central role in all historical aspects of the planetary and Earth sciences.
Dating | Definition, Geology, Methods, & Facts | Britannica
网页dating, in geology, determining a chronology or calendar of events in the history of Earth, using to a large degree the evidence of organic evolution in the sedimentary rocks accumulated through geologic time in marine and continental environments. To date past events, processes, formations, and fossil organisms, geologists employ a variety of ...
Geochronology and radiometric dating | Britannica
网页geochronology, Dating and interpretation of geologic events in the history of the Earth. The classical technique of geochronology was stratigraphy, including faunal succession. Since the mid 20th century, radiometric dating has provided absolute age data to supplement the relative dates obtained from the fossil record.

Introduction to Geochronology | SpringerLink
网页Geochronology means dating of geological events. Although this expression was first used for geological time estimates, based on sedimentation rates, this term is now commonly applied to geological dating, based on …
Geochronology - SpringerLink
网页The science of geochronology provides the fourth dimension of geological and geobiological processes as a crucial requirement for their reconstruction in space and time, e.g., the determination of changes in biochemical fluxes, habitat conditions, and their comparison through Earth’s geological and biological evolution.
Geochronology and Radiogenic Isotopes | SpringerLink
网页2018年1月1日 · Geochronology is the science of determining absolute ages of geological events and Earth materials. It utilizes radioactive isotopes and the production and accumulation of radiogenic daughter isotopes naturally present on Earth. It can be applied to a wide range of samples including rocks, minerals, and …
