    Here we show that carbonate-rich lakes can concentrate phosphate to >1 molal levels by locking up calcium in carbonate minerals, which prevents phosphate removal by apatite precipitation Phosphate-rich lakes may have preferentially formed on the prebiotic Earth because of carbonic acid weathering under CO2-rich atmospheres and the absence of ....

  • Which Minerals Include Phosphate?

    Apatite is a family of minerals centered around fluorapatite, or calcium phosphate with a bit of fluorine, with the formula Ca 5 (PO 4) 3 F Other members of the apatite group have chlorine or hydroxyl that take the place of the fluorine; silicon, arsenic or vanadium replace the phosphorus (and carbonate replace the phosphate group); and strontium, lead, and other elements substitute for the ....
