What is the difference between radiometric and relative dating

Say for example that a volcanic dike, or a fault, cuts across several sedimentary layers, or maybe through another volcanic rock type.Dating is a technique used in archeology to ascertain the age of artifacts, fossils and other items considered to be valuable by archeologists.

For inorganic materials, such as rocks containing the radioactive isotope rubidium, the amount of the isotope in the object is compared to the amount of the isotope's decay products (in this case strontium).Two broad categories of classification methods are relative dating and absolute dating.Though using similar methods, these two techniques differ in certain ways that will be discussed in this article.There are many methods employed by these scientists, interested in the old, to get to know the age of items.It is possible to tell the number of years ago a particular rock or archeological site had been formed.Geologists draw on it and other basic principles ( to determine the relative ages of rocks or features such as faults.
