Abstract
Based on an extensive dataset (44 mineral pairs), we provide the temperature estimates for the crystallization of magmatic olivine (Mg# 88–89) and associated early mineral phases (spinel-group minerals, ilmenite, rutile, and phlogopite) from volcaniclastic kimberlites of the Udachnaya-East pipe. Using several geothermometers (olivine–chromite, olivine–ilmenite, and ilmenite–titanomagnetite), we apply strict compositional constraints corresponding to the calibration ranges of each thermometer to ensure maximum accuracy. In these study additionally presents 96 new chemical analyses of crystalline inclusions within magmatic olivine
