Rutile u pb dating
DOI: 10.31897/PMI.2018.4.357 Introduction and problem statement. The widely known Pizhemskoe titanium deposit and the Ichetju polymineral occurence, located in the Middle Timan (Komi Republic), promise to be in a great demand both in terms of giant titanium and quartz sandstones of glass quality resources and the possible expansion of the list of promising mineral components (rare metals - yttrium, zirconium, niobium, rare earth elements, diamonds, etc.). The main minerals among the 50 indicated are quartz, rutile, anatase, niobium rutile, ilmenite, zircon, mona-zite, columbite, garnets, chromespinelide, tourmaline, staurolite, gold with silver impurities, rounded diamonds of the Urals-Brazilian type . It was established that rutile originates from various sources with different ages (presumably, ca. Along with zircon, known as a universal geochronometer, rutile is widely used for these purposes [9, 12, 17, 21, etc.].
