| Abstract: | Based on the Fe and Mn concentrations in single points of the profiles cutting the crusts of polymetallic nodules CCA33, CCB29, CCC50 and CCC14 from the Clarian-Clipperton Area in the Eastern Pacific Basin, the authors have calculated the instanttaneous growth rates during nodule formation processes, divided nodules formation processes into many stages, determinated stage growth rates, built highresolution time scales in nodule crusts and rebui1t the nodule growth history. These studies suggest that using instantaneous growth rate, a new concept and index, we can start a new way of studying nodule growth history and drawing paleoenvironmental information from nodule records. |
