Phoshorus in carbonate rocks

By statistical processing of more than 7000 complete silicate analyses new, more reliable Clarkеs of Phosphorus (P2O5 and P,%) and phosphorus modules for carbonate rocks and their analogues (unconsolidated young sediments and carbonate metamorphites) were calculated. These Clarkes were noticeably lower than previously calculated. For the first time, a correlation analysis of phosphorus content and values of phosphorus modules with rock-forming components of carbonate rocks was performed, which allowed to clarify the mechanism of phosphorus accumulation.
