Absolute dating also known as radiometric dating is based by the measurement of the content of specific radioactive isotopes of which the "half time" is known. Half time is the time needed for half of a given quantity of an isotope to decay in its byproducts. Comparing the quantity of the parent form and the byproduct will give a numerical value for the age of the material containing such isotopes. Example include carbonnitrogen, uranium-led, uranium-thorium. Relative dating instead allows for identifying the sequential order of geological events one relative to the other.

International law - Wikipedia

Stratigraphy is a key concept to modern archaeological theory and practice. Modern excavation techniques are based on stratigraphic principles. The concept derives from the geological use of the idea that sedimentation takes place according to uniform principles. When archaeological finds are below the surface of the ground as is most commonly the case , the identification of the context of each find is vital in enabling the archaeologist to draw conclusions about the site and about the nature and date of its occupation. It is the archaeologist's role to attempt to discover what contexts exist and how they came to be created. Archaeological stratification or sequence is the dynamic superimposition of single units of stratigraphy, or contexts.

International law

In , Niels Stensen , better known then and now by his Latinized name Nicolaus Steno, formulated a few basic rules that helped him make sense of the rocks of Tuscany and the various objects contained within them. His short preliminary work, De Solido Intra Solidum Naturaliter Contento — Dissertationis Prodromus Provisional report on solid bodies naturally embedded in other solids , included several propositions that have since become fundamental to geologists studying all kinds of rocks. Three of these are known as Steno's principles, and a fourth observation, on crystals, is known as Steno's Law.

Adapted by Sean W. First Edition. View Source. The methods that geologists use to establish relative time scales are based on geologic laws and principles. A scientific law is something that we understand and is proven, and a principle is a guide we use to help us evaluate a system.
