| The Research on 10A Manganese Mineral Phase in the Oceanic Polymetallic Nodules |
| The conclusion of the research on 10A manganese minerals in the oceanic polymetallic nodules have argued for a long time.In order to explore the species of 10A manganese minerals in our research area,the authors choosed thirteen representative samples mainly composed of 10A manganese minerals from more than 100 nodule samples and studied their thermal stability.Three different cases were summarized:The appearance of 7A diffraction peak and the movement of 10A diffraction peak to higher angle show the existence of buserite Ⅰ and asbolane_buserite mixed_layer mineral in the original samples∶The absence of 7A diffraction peak and the movement of 10A diffraction peak to higher angle indicate that there isn't buserite I but asbolane_buserite mixed_layer mineral in the original samples:The absence of 7A diffraction peak and the basic disappearance of 10A diffraction peak illustrate the existence of asbolane in the original samples;The authors explained above phenomena by using the theory of crystal structure and pointed out that the main species of 10A manganese minerals in the nodules in our research area are buserite Ⅰ,asbolane_buserite mixed_layer mineral and asbolane,no or almost no todorokite is present. |
