The isochron method is a radiometric dating technique used to determine the age of a sample by measuring isotopic ratios and plotting them on an isochron diagram. This method helps eliminate the need for assumptions about the initial conditions of the sample, providing more accurate age estimations in geochronology.

Isotopic ratios tell us how many different kinds of the same atom are in something, like how many apples and green apples are in a basket. Scientists use these ratios to learn about the history of rocks, water, and even the air we breathe.

Geochronology is the science of determining the age of rocks, fossils, and sediments, which provides a timeline for Earth's history and the evolution of life. This field uses a variety of dating methods, such as radiometric dating, to establish absolute and relative time scales, enabling researchers to reconstruct past geological events and understand the planet's development over billions of years.
