2017/4/11
Recently, how to quantitatively estimate the growth rate of continental crust is an enigmatic issue. With the development
of ICP-MS technology, the U–Pb dating and Lu–Hf isotopic compositions of detr...
Coral growth-rate insensitive Sr/Ca as a robust temperature recorder at the extreme latitudinal limits of Porites
skeletal oxygen isotope in the coral Sr/Ca high latitudes coral growth rates
font style='font-size:12px;'>
2017/4/11
Oxygen isotope values of low-growth coral (<5 mm/yr) skeletons may reflect kinetic effects, which is problematic for
sea surface temperature (SST) reconstruction. Here, we report a Sr/Ca-based SST re...
Simple relationship between 26Al production rate and major elemental composition of meteorite samples
production rate 26Al terrestrial age howardite eucrite

2017/4/11
Estimation of 26Al (half-life = 705 kyr) content at the time of meteorite fall is required to calculate the terrestrial age
of meteorites using the 26Al content. Previous studies (e.g., Cressy, 1971;...
