| सारांश≠ | Radiocarbon dating is a radiometric technique that determines the age of organic materials by measuring the radioactive decay of ¹⁴C (carbon-14), a rare isotope produced in the atmosphere by cosmic ray interactions. Developed by Willard Libby in 1949, radiocarbon dating became a foundational method in archaeology, paleoclimate studies, and geology, enabling dating of organic materials from the past ~50,000 years with typical precision of ±50–100 years. | Paleomagnetic analysis is the study of remnant magnetization in rocks and sediments to determine the direction and magnitude of the Earth's ancient magnetic field and to establish the ages and tectonic histories of crustal rocks. Formalized by Fisher (1953) and Butler (1992), paleomagnetism underpins plate tectonics plate reconstruction, magnetostratigraphic dating, and paleoclimate studies. |
