页岩中结核类型及成因研究

Study on the types and genesis of nodules in shale

结核是页岩中十分常见又复杂的一种沉积构造,其成分、结构、颜色等与围岩截然不同,在揭示构造活动、古环境、古物源和成岩作用等方面具有重要意义。因此,通过对结核的概念、页岩中结核类型、成因及地质意义等方面进行总结,为页岩成因研究提供参考。

Concretion is a very common and complex sedimentary structure in shale,which composition,structure,color is completely different from the surrounding rock.Concretion is of great significance in revealing tectonic activity,ancient environment,ancient material sources,and diagenesis.Therefore,this article summarizes the concept of concretion,types,genesis,and geological significance of concretion in shale,providing reference for the study of shale genesis.
