Chemical composition of manganese crusts fom the Southwest Pacific Ocean

During cruise L582SP of R/V Lee from USGS, dredges performed on the Tonga ridge have retrieved manganese crusts deposited on sandstone formations. These samples have been analysed using atomic absorption spectrophometry techniques.

在美国地质调查局（United States Geological Survey, USGS）所属‘李号’（R/V Lee）科考船的L582SP航次期间，于汤加海岭开展的深海拖网采样作业采集到了附着于砂岩地层之上的锰结壳。上述样品已通过原子吸收分光光度法完成分析。
