摘要
锰矿物是深海环境及地表常见的可再生矿物,锰矿物的形成和物相的转化与地球化学演变具有重要的关系。深海环境中的锰矿化物的物相转变,与微生物作用及热液活动具有重要的关联。因此,为了探寻锰矿化物的物相转变的特征及转变过程,利用拉曼光谱分析、XRD分析、扫描电镜、投射电镜等技术,开展了微生物作用及低温热液作用对锰矿化物物相转变的实验。研究表明,微生物作用可促使水钠锰矿化物转化为低价锰矿化物,而热液作用可使得三斜水钠锰矿化物转化为钡镁锰矿化物。
Manganese minerals are common renewable minerals in deep-sea environment and earth surface. The formation of manganese minerals and the transformation of their facies are of great importance to geochemical evolution. The phase transition of manganese minerals in deep-sea environment has very important associations with microbial activities and hydrothermal activities. Therefore, in order to explore the characteristics and transformation process of phase transition of manganese ore, Raman spectrum analysis, XRD analysis, scanning electron microscope,and projective electron microscope were used to carry out the experiment of microbiological action and the effect of low temperature hydrothermal action on the phase transformation of manganese mineralizer. The study shows that microorganism can promote the conversion of sodium manganese ore into low manganese ore, and the effect of hydrothermal solution can convert trichroic sodium manganese ore into barium magnesium manganese ore.
