Dating the particles which make up the rock wouldnt give you the age of the rock itself.
Rocks cannot be dated directly using radiometric dating, which is based on the idea that when rocks are in liquid form, their radiometric clock resets.
Dating sedimentary rock layers
Nuclear decay of radioactive isotopes is a process that behaves in a clock-like fashion and is thus a useful tool for determining the absolute age of rocks.
Apwps for different continents can be used as a reference for newly obtained poles for the rocks with unknown age.
Sedimentary rock absolute dating
:inclusions, which are fragments of older rock within a younger igneous rock or coarse-grained sedimentary rock, also facilitate relative dating.
Rocks - Is it true that scientific dating techniques used to determine the age of materials have limitations?
Age dating of sedimentary rocks
Believe they can indirectly date sedimentary rocks using radiometric dating if they find igneous or metamorphic rock imbedded in or around a sedimentary rock layer.
Most ancient sedimentary rocks cannot be dated radiometrically, but the laws of superposition and crosscutting relationships can be used to place absolute time limits on layers of sedimentary rocks crosscut or bounded by radiometrically dated igneous rocks.
Often applied to the trace mineral zircon in igneous rocks, this method is one of the two most commonly used (along with argon-argon dating) for geologic dating.
 first method is used for paleomagnetic dating of rocks inside of the same continental block.
However, in order to place absolute dates on the relative time scale, other dating methods must be considered.
Relative dating techniques provide geologists abundant evidence of the incredible vastness of geologic time and ancient age of many rocks and formations.
Burial dating uses the differential radioactive decay of 2 cosmogenic elements as a proxy for the age at which a sediment was screened by burial from further cosmic rays exposure.
Is the science of determining the age of rocks, fossils, and sediments using signatures inherent in the rocks themselves.
