Manganese nodule - Wikipedia

Manganese nodules « World Ocean Review,Manganese nodule treasures > Many thousands of square kilometres of the deep-sea floor are covered by metal-bearing nodules They contain primarily manganese, but also nickel, cobalt and copper, which makes them economically promisingManganese nodule | mineralogy | Britannica,Other articles where Manganese nodule is discussed: authigenic sediment: Manganese nodules are pebbles or stones about the size of walnuts that are built of onionlike layers of manganese and iron oxides Minor constituents include copper, nickel, and cobalt, making the nodules a potential ore of these valuable elements

Manganese nodules - creation

These ‘baby’ nodules will usually begin to develop only cm or mm below the sediment As the nodule matures, chemicals will also accumulate via precipitation from sea water adding more mass, eventually leading to what we see today Manganese nodule growth rates Figure 2Manganese Nodule Discovery Points to Genesis Flood | The ,Second, they are typically found only in the uppermost 50 centimeters (about 20 inches) of sediment 2 Scientists have drilled and extracted cores from seafloor sediments, and manganese nodules are sometimes found within the deeper sections of these sediment cores Yet even most of these buried nodules lie within the uppermost core sections Are manganese nodules examples of biogenous sediment?,Manganese nodule is what kind of sediment?
