The uranium-lead method
relative dating
Radio-active decay
gravity method
Geochronology is the method of determining the absolute age of rocks, using radiometric methods.
Based on their method of formation.
Igneous rocks can be classified by their method of formation and by their mineralogy.
This is known as radiometric dating.
Radiocarbon dating is a commonly used dating method for organic materials up to about 50,000 years old. It is based on the decay rate of carbon-14 isotopes. Potassium-argon dating is another method used for dating rocks and minerals, providing accurate dates for materials over longer time scales, up to billions of years.

something to do with science and rocks
Dating rocks age.
The radioactive decay of carbon, called "Carbon 12 dating". It isn't perfect, but it is usually accurate to within about 1,500 years, which makes it a very useful tool.
Igneous rocks do not contain much carbon.
Igneous rocks vary greatly in composition and method of formation, resulting in diverse densities.
The three kinds of rocks by their method of formation are IGNEOUS rocks, SEDIMENTARY rocks and METAMORPHIC rocks. Igneous rocks cool from magma or lava. Sedimentary rocks form by the deposition of particulates and silt. Metamorphic rocks form from rocks (usually sedimentary) that are compressed and heated underground.

I'd say 2GB, but 4GB rocks. I know.
