Radiometric dating is least useful for dating


These are ones produced by decay of the long-lived radionuclides given in the upper part of Table 1. The age of a particular sample, and a particular geological time scale, only represents the current understanding, and science is a process of refinement of that understanding. Material that solidifies in such cracks remains behind as dikes. Now, igneous bodies can be of two types, extrusive and intrusive. So the problem must be solved by a host of assumptions that will probably never be tested. Rocks that flow in a plastic state record their deformation in the alignment of their constituent minerals. Radiometric dating has simply made the estimates more precise, and extended it into rocks barren of fossils and other stratigraphic tools. By measuring the concentration of the stable end product of the decay, coupled with knowledge of the half life and initial concentration of the decaying element, the age of the rock can be calculated. The effect is almost always a very small departure from homogeneous distribution of the isotopes -- perhaps enough to introduce an error of 0. In general, in one half-life, half of the parent will have decayed. Some fossils are found in Precambrian rocks, but most of them are found in Cambrian and later periods. In the latter case, refractory grains in particular may record the original age of the rock in their cores and the time of melting in their newly grown tips.
