| Abstract: | The mineral and microelement composition and structures have been studied and a comparative analysis has been carried out for manganese minerals with the general formula Mn(O,OH)2]+R0.5–1(OH)21.5] · nH2O (R = Mn, Na, K, Ni, Co, Ca, and others) that built iron-manganese concretions raised from different areas of the Sea of Okhotsk and the Bering Sea, and their synthetic analogues. The structures of synthetic manganese species were found to better withstand temperature impacts than those of the native minerals studied under the same conditions. |
