DISTRIBUTION CHARACTERISTICS OF CARBONATE, MgO, CaO IN THE SEDIMENTS FROM THE CENTRAL PACIFIC |
|
Abstract: |
This paper is a preliminary study of the distribution characteristics of carbonate, MgO, CaO in the sediments from the central pacific. In the investigation area, the depth of water and type of sediments are important controlling factors on the distribution of carbonate, MgO, CaO in sediment. In the surface sediments, the content of carbonate and CaO decreased with the increase of the depth of water, but the plot of the MgO content against the depth of water appeared to be bell shaped. "The dissolution transition layer " and "Carbonate compensation depth(CCD)"occurred at the depth of about 3000-3500m and 5000m. |
