大洋富钴结壳的基本框架——超微生物建构的锰质叠层石柱体
The basic frame of oceanic cobalt-rich crusts—manganese stromatolite columns constructed by ultramicrobes

摘要: 大洋富钴结壳和锰结核一样是潜在的海底矿产资源,对其成因的研究将有助于指导找矿和资源评价。通过大型反光显微镜、透射电子显微镜和其他测试手段,系统研究了结壳的结构构造、物质组成以及叠层石纹层与超微生物的关系。发现结壳与光滑型锰结核的叠层石类型及超微生物种极其相似,它们都以微小叠层石和中华微放线菌为主要特征,具有相同的生物成因机制。认为超微生物建构的锰质叠层石柱体是大洋富钴结壳的基本框架,从而对结壳矿体的形成提出了新的见解。Abstract: The oceanic cobalt-rich crusts as same as the manganese nodules, are the latent mineral product of oceanic bottom.Studying their formation will help to lock for the mineral deposits and assessment of resources.The texture and structure, matter composition of cobalt-rich crusts and the relationships between stromatolite laminae and ultramicrobes are systematically studied by the reflection light microscope and transmission electron microscope, as well as other analysis methods.It is found that cobal-trich crusts are similar to the smooth manganese nodules in stromatolite type and ultramicrobe species: The both have minima and Miniactinomyces chinesis.They have similar organogenic mechanism.It is considered that the ultramicrobes are constructors of the basic frame of oceanic cobalt-rich crusts (manganese stromatolite columns), and thus a new view on the crust's formation is advanced.
