Dating of sedimentary rocks

ANSWER: Sedimentary 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.

QUESTION: Can we date sedimentary rocks using radiometric dating techniques?Radioactive elements are unstable; they breakdown spontaneously into more stable atoms over time, a process known as radioactive decay.Radioactive decay occurs at a constant rate, specific to each radioactive isotope.Therefore, as calcium carbonate is deposited and turns into sedimentary rock, it leaves a chemical fingerprint of the animals and their environment, and of the plants and bacteria that were there at the time.It has always been difficult to distinguish between microbial and non-biological contributions to calcium carbonate rock formations.
