Combined EPD and HS mineral processing technology of bedrock samples allows ideal liberation of crystals, grains and particles of different minerals followed by their successful hand-picking under binocular microscope to collect sufficient amount of high-quality research-grade mineral separates for geochronology (age-dating by U-Pb, K-Ar, Ar-Ar, Rb-Sr, Sm-Nd, Re-Os and other methods), indicator mineralogy (liberation and concentration of Zircon, Apatite, Monazite, Feldspar, Baddeleyite, Sericite, Illite, Biotite, Muscovite, Hornblende, Garnet, Sulphides etc.), crystallography, micropaleontology (microfossils) etc.
