| contents | Shape of the 230Th vertical distribution curve ideally close to exponential is studied to determine isotopic age of deep-sea sediments. In practice such ideal 230Th vertical distribution curve is rarely occur; secondary maxima and minima often appear on it. It has been shown that oxyhydroxides of Fe, Mn, and also Corg and P are of prime importance for 230Th concentration. A method is offered for normalizing the vertical distribution curve of 230Th based on taking into account content of these elements in sediment. |
