<sup>40</sup>Ar/<sup>39</sup>Ar DATING OF MARUYAMAITE (K-DOMINANT TOURMALINE) FROM DIAMOND-BEARING METAMORPHIC ROCKS OF THE KOKCHETAV MASSIF

40Ar/39Ar analyses were made on maruyamaite (potassium-dominant tourmaline) from tourmaline-quartz-feldspar rocks discovered within the Kumdy-Kol microdiamond deposit (Kokchetav massif, North Kazakhstan).
