Why is radiometric dating on sedimentary rocks usually unsuccessful?

Why is radiometric dating on sedimentary rocks usually unsuccessful? Sedimentary rocks form from many older rock particles. Sedimentary rocks never have particles that contain radioactive isotopes. Sedimentary rocks form too quickly to be accurately dated.

What is wrong with radiometric dating?

Here is yet another mechanism that can cause trouble for radiometric dating: As lava rises through the crust, it will heat up surrounding rock. Lead has a low melting point, so it will melt early and enter the magma. This will cause an apparent large age. Uranium has a much higher melting point.

What are the three records of sedimentary rocks?

There are three basic types of sedimentary rocks.Clastic sedimentary rocks form from the accumulation and lithification of mechanical weathering debris. Chemical sedimentary rocks form when dissolved materials preciptate from solution. Organic sedimentary rocks form from the accumulation of plant or animal debris.
