Inclusion relative dating
This is used for evaluation of the age of a rock using the so called radiometric methods In determining the absolute age of a rock different methods are used Uranium – Lead, Uranium – Thorium, Potassium – Argon, Rubidium – Strontium, Carbon “Fission Tracks” and Thermoluminescence.In determining the chronology of rocks and facies of all marine, mixed and continental sediments, the fluctuations and changes in the order of land and sea in Earth’s past are followed.Steno reasoned that strongly tilted rocks did not start that way, but were affected by later events—either upheaval by volcanic disturbances or collapse from beneath by cave-ins.Today we know that some strata start out tilted, but nevertheless this principle enables us to easily detect unnatural degrees of tilt and infer that they have been disturbed since their formation.
This principle allows us to piece together the succession of fossil life that defines much of the geologic time scale.
The age of a rock is determined by stratigraphy, a branch in geology which studies the chronology of events and changes, along with the development of organisms, which have determined the development of the Earth from when it became an independent spatial body until today.
The age, or the chronology of geological creations and events is determined using relative and absolute age.
The quotes given here are from the English translation of 1916.
"At the time when any given stratum was being formed, all the matter resting upon it was fluid, and, therefore, at the time when the lower stratum was being formed, none of the upper strata existed." Today we restrict this principle to sedimentary rocks, which were understood differently in Steno's time.This method has been developed as part of paleontology – science concerned with fossils and development of life through geological history.
