Isotopic dating is valuable in correlating sections and constructing regional or general stratigraphic scales; particular importance attaches to Precambrian formations, for which classical stratigraphic, paleontological, and lithological techniques are ineffective or less reliable than in the Phanerozoic. Considerable advances in this field have been made in the last 15-20 years: the Rb-Sr method has made it possible to date clayey sediments, which are common in beds of virtually all ages. The topic is complicated and requires not only the solution of special analytical problems but also reliable confirmation of methods. This paper discusses lithological basis, mineralogical and geochemical basis, dimensions of clay minerals, the processes dated, and model forms of dating for clayey rocks. Results of dating several deposits are discussed. 39 references.
