Primary U distribution in scleractinian corals and its implications for U series dating
uranium diagenesis coral dating.
2014/4/9
In this study we use microsampling techniques to explore diagenetic processes in carbonates. These processes are important as they can affect the accuracy of U series chronometry. Fission track maps o...
Fe3+-Rich Montmorillonite-Beidellite Series in Ayvacik Bentonite Deposit, Biga Peninsula, Northwest Turkey
