Isochrons

Isochrons are lines on a map or graph that connect points representing equal times. In geology, for example, they illustrate when different rocks or geological features were formed. By analyzing the age of various samples relative to each other, scientists can determine the timing of events in Earth's history. Isochrons help in understanding processes like volcanic eruptions or the timing of tectonic shifts, providing a clearer picture of how geological formations and events occurred over time. Essentially, they are tools for visualizing the timing of changes in the Earth's surface.
