Rock formed as the earth was pulled together by gravitational attraction. Consequently the planet grew in size. One major constituent of the new planet was cal- cium. Water formed from hydrogen and oxygen. This filled the valleys and ocean basins of the earth. Water washed the rocks of the earth, leaching out elements including calcium into the ocean. Calcium is still being deposited into the oceans as sedimentary CaCO, from combina- tion with carbon dioxide (Fig. 1). See Figure 2 for the biogeochemistry of calcium. Ancient calcium "The calcium carbonate of the rivers would supply this substance in 5 X 105 years. This has been deposited as sedimentary limestone.
