The difference was startling. One of the crucial experiments which the group performed was to draw water from the hot springs vent andmeausre how much calcium carbonate was deposited with the microbes present. However, sedimentary rocks can be age dated if a volcanic ash horizon or a diabase sill or dyke can be found within the sequence. It may start to grow during early diagenesis, typically forming syntaxial outgrowths on detrital zircon grains. Radioactive elements decay at a certain constant rate and this is the basis of radiometric dating. 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 difficult. 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. Volume 68, Issues 3—4 , January , Pages Radiometric dating of sedimentary rocks: When these creatures die, their shells are incorporated as part of the sedimentary rock.
