"Dragon" third leg for the first time to dive samples taken back to a cobalt-rich crusts


"Dragon" today (September 3) in the Pacific Northwest Association of China Ocean crusts mining exploration contracts Weihai mountainous district implemented the first 69 dives job, which is the "Dragon", the first pilot applications voyage The third leg of the first dive, samples taken back to a cobalt-rich crusts. Geology, State Oceanic Administration, Dr. Tang Limei that two of the samples for the study of its metallogenic mechanism, as well as with different occurrences of crusts contrast is important.To learn more please visit: http://www.solarpanelcellonline.com/

Tang Limei said that crusts are widely distributed in the Western Pacific, mainly in seamounts, ridges and Taiwan (with a relatively flat, wide top surface of the seabed Heights) slope. About 50,000 Pacific seamounts, which crusts most abundant storage capacity, but after detailed investigation and sampling of seamounts are few.

She said that the diversity of source material crusts, generally considered to be adsorbed metal element manganese mixed colloidal precipitate formed, bacterial activity in this process played an important role. Crusts usually a few millimeters per million annual growth rate of formation, and become a thick crust, may require thousands of years old, is the Earth's most natural process of slow one.

It is understood that crusts contained in cobalt, manganese, nickel and other metals used in alloys that can increase its hardness, strength and corrosion resistance and other special properties. In some industrialized countries, a large number of cobalt is used in the aerospace industry super alloy production. And high in the chemical industry, the cobalt can also be used in the production of photovoltaic cells, solar cell , fuel cells, superconductors, high-level laser system, a catalyst, a strong magnetic and cutting tools and other products.

The dives also obtained a six wrist starfish, four seamount rocks and two sediment samples, photographed corals, sponges, starfish, sea fish and other marine life information.

Field chief scientist Wang Chunsheng introduced through the dive, found that the giant sea benthos low abundance middle of last month, "dragon" probed Wei seamounts, in line with the characteristics of oligotrophic waters; wrist found in this area six starfish benthic organisms such giant, giant creatures have further illustrate the characteristics of wide distribution.
