• 钙锰矿

  The transformation of birnessite→buserite→todorokite is an important pathway for todoroktie formation.

  水钠锰矿→布塞尔矿→钙锰矿的转化是钙锰矿形成的一个重要途径。

• 钡镁锰矿

  The manganese-dominant mineral of Cobalt-rich crusts in this area isδ-MnO_2, for the three main manganese minerals of todorokite, birnessite andδ-MnO_2 in deep seas,δ-MnO_2 is the most thorough oxidized mineral, the O/Mn are 1.74~1.87,1.87~2.00,1.99.

  3.研究区富钴结壳的锰矿物为δ-MnO_2,前人研究表明:在最主要的三种深海锰矿物钡镁锰矿、钠水锰矿和δ-MnO_2中,δ-MnO_2是氧化最彻底的矿物,三者的O/Mn值依次为1.74~1.87,1.87~2.00,1.99。
