Detailed sectioning and analysis reveal that there are discontinuous gradients in²²⁶Ra content in these samples. These gradients result from periods of rapid growth (&gt;1 mm/100 years) separated by periods of no growth of erosion. Although the²²⁶Ra “age” of the nodules approximates the age of Oneida Lake, the nodules are not sediment-covered because they occur only in areas of the lake where fine-grained sediments are not accumulating.</p></div></div></div> application/pdf 10.1016/0012-821X(80)90005-9 en Elsevier Growth rates of manganese nodules in Oneida Lake, New York article
