DISTRIBUTION FEATURE OF IRON MANGANESE ALUMINIUM AND CALCIUM CARBONATE IN SEDIMENTS IN MANGANESE NODULE FIELD, NORTH PACIFIC OCEAN |
| |
| Abstract: | The data of iron manganese aluminium and calcium carbonate in 55 sediment samples of manganese nodule field from the North Pacific Ocean has been analysed. The content of iron manganese aluminium and calcium carbonate in the sediment were mainly controlled by water depth, the calcium carbonate content increased with decrease of water of depth. Whereas, the iron manganese aluminium content increased with increase of water of depth. The elements content is closely related to sedimentary type. The iron manganese aluminium content increased with the decrease of grain-size of sediments. Therefore, the calcium carbonate content increased with the increase of grain-size of sediments. The relationship between manganese aluminium and iron can be expressed by the equations (YMn= 44.80 XFe-6.18, r= 0.92) and (YA1 = 0.54 XFe-0.42, r= 0.97). Whereas the relationship between iron and calcium carbonate can be expressed by the equation (YFe = 92.55 Xc2co3, r= -0.96). |
