Portions of the reason why rarely dating of sedimentary rocks is dated directly by its association in sedimentary rocks are the ages imprecise. Relative to circle study we will decay products of one of rock or trace element.
Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Over naturally-occurring isotopes are known.
Radiometric dating is commonly used on igneous rocks (lava), and on some sedimentary minerals. But fossils can generally not be dated directly. When lava is hot, argon escapes, so it is generally assumed that no argon is present when lava cools.
It is currently possible to date igneous and metamorphic rocks by a variety of radiometric methods to within a million years, but establishing the depositional age of sedimentary rocks has remained exceedingly [HOST] by:

This is the most widely used system for radiometric dating of sedimentary strata, because it can be used to date the potassium-rich authigenic mineral glauconite and volcanic rocks (lavas and tuffs) that contain potassium in minerals such as some feldspars and micas.
Radiometric dating, radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant.
Sedimentary rocks may have radioactive elements, but they are precipitated from other rocks, which means that the radiometric clock cannot be set to zero. One example is one of the potassium isotopes, potassium , which is radioactive and decomposes into two different daughter elements (potassium in argon 40) in a ratio of % to %.
Why can’t we use isotopic dating techniques with sedimentary rocks? An important assumption that we have to be able to make when using isotopic dating is that when the rock formed none of the daughter isotope was present (e.g., 40 Ar in the case of the K-Ar method). A clastic sedimentary rock is made up of older rock and mineral fragments, and when the rock forms it is almost certain that.
