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...
