metadata.name: dc.description.abstract
metadata.value: The article is devoted to studying of isotope-geochemical characteristics of phosphorite and
  the enclosing carbonate Karatau Phosphorus deposit. As a result of the work on the identification
  of the least altered rocks, the primary isotopic composition of Sr, C and O in the water
  of the Karatau basin was established, as well as the isotopic composition of Nd phosphorites.
  Kyrshabakty Formation underlying phosphorite characterized 87Sr/86Sr ratio 0.70839, δ13C
  value ranges from +0.2 to 0.6 ‰. The primary Sr isotopic composition of the phosphate-bearing
  Chulaktau Formation, varies from 0.70877 to 0.70905, and the carbon isotope composition
  ranges from –3.1 to 0.8 ‰. Based on these data, the sedimentation interval of these rocks
  was established. Phosphate accumulation within the Karatau basin occurred in the range of
  520–509 million years ago as a result of biogenic precipitation of the phosphorus of ocean
  water on the shelf of the passive margin of the continent.
