Two Types of Granites in the Western Yangtze Block and Their Implications for Regional Tectonic Evolution: Constraints from Geochemistry and Isotopic Data
I-type granite S-type granite geochemistry petrogenesis tectonic setting Western Yangtze Block
2018/4/10
In the western Yangtze Block, widespread Mesoproterozoic to Neoproterozoic rocks are the key to understanding the Precambrian tectonic-magmatic evolution of the region. However, their petrogenesis and...
The I-Xe chronometer and its constraints on the accretion and evolution of planetesimals
extinct radioisotopes iodine-xenon chondrites early solar system chronology
2017/4/10
We report a –1.6 ± 2.6 Myr (1s error) I-Xe age of the ungrouped achondrite NWA 7325 relative to the Shallowater
standard. We re-evaluate the calibration of the relative I-Xe dating system against the...
Heat and mass transfer from the mantle: heat flow and He-isotope constraints
heat flow helium isotope ratio geothermal energy mass transfer
2015/9/10
Terrestrial heat flow density, q, is inversely correlated with the age, t, of tectono-magmatic activity in the Earth's
crust (Polyak and Smirnov, 1966; etc.). «Heat flow-age dependence» ind...

O2 constraints Paleoproterozoic detrital pyrite uraninite
2014/4/8
Redox-sensitive detrital grains such as pyrite and uraninite in sedimentary successions provide one of the most conspicuous geological clues to a different composition of the Archean and early Paleopr...
Growth rate of continental crust in the northeast margin of the North China Craton: Constraints from the U–Pb dating and Lu–Hf isotopes of detrital zircons from the Laoha River
North China Craton detrital zircon U–Pb age Hf isotope Laoha River
2017/4/11
Recently, how to quantitatively estimate the growth rate of continental crust is an enigmatic issue. With the development
