Abstract
Hydrothermal veins of Muruntau gold-ore deposit (Central Kyzylkum) hav e been studied by using isochrone technique. The analysis of fractions with different densities gave isochrones with the following parameter s: Hydrothermal veins (Sr-87/Sr-86) T, Ma Quartz-tourmaline 0.71527 +/ - 39 257 +/- 13 Quartz-arsenopyrite 0.72065 +/- 9 230.2 +/- 3.5 Quartz -adularia 0.751 +/- 8 219.4 +/- 4.2 The ages obtained reflect the diff erent stages of the deposit evolution: gold-ore and gold-silver one. S trontium isotope analysis reveals the matter of hydrothermal veins is originated from the surrounding black schists.
