Paul Renne, director of the Berkeley Geochronology Center, which specializes in dating rocks, said the researchers made "a reasonably good argument" to support their dating of the fossils.
Geochronology is the science of measuring ages, rates, and histories of geologic or planetary materials, and using these insights to understand processes and phenomena in earth and planetary science.
According to isotopic geochronology, intrusion of Yunmengshan plutons happened in Middle Yanshanian.
Geochronology: the study of time in relation to the history of the Earth.
This paper studied the geochronology of sandstone - type uranium deposit in the Dongsheng area of Ordos Basin.
His doctoral thesis was devoted to the geochemistry, geochronology and nuclear chemistry of the noble gases xenon and krypton.
As isotope geochronology uses the elements of long half-life to determine the geological age, the half-life through out the period may be considered to be constant.
Development of geochronology from isotopic chronology to tectonic chronology must evolve several stages including ther- mal chronology, tectono-thermochronology and deformation chronology.
Geochronology is an important fundamental branch of modern geology, which was coming into being in the early 20 century and got rapid development in 1950s and 1960s.sentencedict.com
