If igneous or metamorphic ( though metamorphic rock is hard to do ) radiometric dating can be used. The radioactive substance that may be in igneous rock devolves into a daughter substance and the rate of this change, coupled with other parent/daughter changes, give one a very precise age on the rock being examined.

It is best determined by radiometric dating techniques which measure the decay of radioactive elements.

Absolute geologic age is determined through radiometric dating, and is the most precise method for determining the age of a rock or fossil within a small range. Relative geologic age is determined by the index fossils that may be contained within the rock that indicate a much broader range of possible ages based on the time the organism existed on Earth.
The absolute age of a rock is determined by the amount of decay of certain elements as interpreted from their known half-life. The absolute age is stated in a number of years with a margin of error, as opposed to the relative age, which is more of a range of years in which the rock could have formed, based on index fossil evidence and the law of superposition.
The age in years of a rock or other object is known as Absolute Age.
Absolute age is the age of a rock as determined by the measurement of radioactive decay from the time of the rock's formation.

The method used will be determined by the rock type, but the age of a rock will be determined by a determination of the amount of decay of a radioactive isotope, either contained in the rock, or in a geologic layer of rock coinciding with a fossil.
Relative age can be determined using superposition and cross-cutting relationships. Absolute age can only be determined using radiometric dating methods, such as Rb-Sr.
Through Radioactive Dating or Isotopic Dating.
The absolute age of rock is determined by the amount of radioactive decay, not by the rate of erosion and deposition.
Radioactive dating is used to determine the absolute ages of rocks. By Jennifer Palos
Relative age is the age of a rock relative to the rock layers around it, absolute age is a rock's exact age.
