Resumo

In the present work, based on a substantial dataset (43 pairs), we provide estimates of variations in crystallization temperatures of magmatic olivine in kimberlites with Mg# 88–89, as well as crystalline inclusions of spinel-group minerals, ilmenite, rutile, and phlogopite in such olivine. The estimates were obtained using different geothermometers (olivine–chromite, olivine–ilmenite, and ilmenite–titanomagnetite pairs), with careful consideration of compositional variations of the minerals used for calibration. Olivine with Mg# 88–89 is the most widespread by volume among the zones of magmatic olivine crystallization in individual grains from the volcaniclastic kimberlites of the Udachnaya-East pipe. In addition, the study reports 96 chemical analyses of the above-mentioned crystalline inclusions in this olivine.
