All dating methods today can be grouped into one of two categories: .The former gives a numeric age (for example, this artefact is 5000 years old); the latter provides a date based on relationships to other elements (for example, this geological layer formed before this other one).Lead-lead dating: Another method that studies the chemical attributes of rocks, it's largely been superseded by uranium-lead dating in geological studies.However, it remains useful to astronomers and astrophysicists in dating meteorites and other extraterrestrial deposits on Earth.These energy levels are measured against what they should be if they had not been interfered with and we are able to obtain a date of the intervention.This is used in archaeological and anthropological contexts (7) in areas where radiocarbon dating is problematic such as dating post AD1700 and where dates from RC14 is anomalous or lacks data. Potassium-argon dating: Typically used in geology and geochronology, K-Ar dating has a minimum age of around 100,000 years ago (but can be problematic when examining material close to this earliest date) up to a top end of around 4.5 billion years.Ever since The Enlightenment, and possibly even before that, researchers have attempted to understand the chronology of the world around us, to figure out precisely when each stage in our geological, biological and cultural evolution took place.

But they can also show human intervention such as when woodland was cleared to make way for agriculture (6).The pre-enlightenment understanding of our geological and cultural history may now be proven wrong and subject to ridicule, but the principles of defining our place in time in the cosmos underpin many sciences.As technology advances, so do our methods, accuracy and tools for discovering what we want to learn about the past.The second is water deposition which essentially “freezes” that magnetic particle in places (5).
