Pb-Sr-Nd isotope characteristics of mantle sources of kimberlites from the Nakym field (Yakutia)

For the first time presented are U-Pb isotope analysis data for three kimberlite samples from two Nakyn field pipes (Botuobinskaya and Nurbinskaya) in combination with their new Sr-Nd characteristics and ICP-geochemistry. RE distribution spectra in kimberlites from two pipes are identical and have t...

Description
Summary:For the first time presented are U-Pb isotope analysis data for three kimberlite samples from two Nakyn field pipes (Botuobinskaya and Nurbinskaya) in combination with their new Sr-Nd characteristics and ICP-geochemistry. RE distribution spectra in kimberlites from two pipes are identical and have the same negative Th, U, Nb anomalies as well as lowered LRE content; Sr and Nd isotope compositions for two pipes are somewhat various. The Pb isotope composition behavior is correlated with the Sr-Nd data.
