Abstract

Olivine (forsterite, rarely chrysoline) is characteristic mineral of alkaline-ultrabasic rocks in Noth-Western region of the Ukrainian shield. These rocks (melteigites, jacupirangites, melteigine-porphyries) form hypabissal intrusions and dikes. Olivines are earliest minerals but sometimes content inclusions of Cr-spinelids. Magnesian olivines are characterized by increased Cr and Ni contents, sometimes CaO that is typical for magnesian alkaline-ultrabasic rocks. By chemistry studied olivines are similar to those in kimberlites and lamproites.
