Geochronology of Metasomatic Events
2012In order to date any geological event, suitable mineral geochronometers that record that and only that event must be identified and analyzed. In the case of metasomatism, recrystallisation is a key process that controls both the petrology and the isotopic record of minerals. It can occur both in the form of complete neocrystallisation (e.g.

Accurate knowledge of climate variations in the past is an essential preamble to any realistic modeling of future climate, and requires an understanding of the mechanisms that govern the natural dynamics of the climate, and especially of its rapid changes.

There are marked similarities in between laterites of India and Australia because these continents have moved from polar to tropical palaeolatitudes over the past 80 million years. On the basis of palaeolatitudes and laterite magnetizations, the favourable optimum climate of laterite formation was prevailed in India from Late Cretaceous to Late ...

Geochronology as based on Solar Radiation
Science, 1927In the article by Dr. G. De Geer on the "Geochronology as based on Solar Radiation" (SCIENCE, 1927, LXVI, p. 458), in line 14 of the second column for "this" read "the," in line 22 of the fourth column omit the words "already made" and in line 37 of the fifth column for "non" read "now."

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.
