八十年代初期覆盖于浅海火山堆积物坚硬基岩上的海洋铁锰结壳被认为是一种钴的潜在经济来源。现在看来铂在铁锰结壳中也有相当的富集。但控制这些金属富集的地球化学机制及地质学与海洋学条件却了解得不多。本文通过对马绍尔群岛拉塔克岛链中铁 Marine ferromanganese crust, which covers the hard bedrock of shallow volcanic deposits in the early 1980s, is considered to be a potential source of cobalt. It now appears that platinum is also quite enriched in ferromanganese crusts. However, little is known about the geochemical mechanisms and geological and oceanographic conditions governing these metal enrichments.
