Lectures in isotope geology / Лекции по изотопной геологии

Geochronology means dating of geological events. Although this expression was first used for geological time estimates, based on sedimentation rates, this term is now commonly applied to geological dating, based on radioactive decay and spontaneous fission.
Geochronology is a discipline that lies between the earth sciences, physics, and chemistry. The problems of geochronology are twofold: technical problems dealing with the highly sophisticated methods of age determination on one hand and the more intuitive approach of the earth sciences on the other hand. Geochronology is therefore the ideal discipline for teamwork. The experimental part of geochronology covers the wide field from trace element chemistry to mass spectrometry with electronics and computer application-and last but not least, mineral separation and all the techniques of mineralogy. Within the last few years the precision of age determination has been improved considerably, to some extent owing to the challenge of working on moon material <...>
