title: Rutile From the Zelenyi Yar Titanium-Zirconium Placer and Its Possible Primary Sources
abstract: Rutile of the Neogene-aged Zelenyi Yar titanium-zirconium placer was studied. The average size of the rutile grains is 0.25 mm that are elliptical, rounded, short-prismatic, isometric, and elongated-prismatic crystals in shape. On the surface of the crystals, elements of physical abrasion of varying degrees, as well as chemical dissolution, are observed. The color of the rutile crystals ranges from black to yellow with black and brown being the most common. A relationship between the concentrati
