中文摘要:本文以蓟县地区高于庄组发育的臼齿构造为例, 通过对臼齿构造详细的岩石学、形态学和岩性与流变学的关系, 以及追踪具独特岩性的臼齿构造母岩的变化。结果表明, 微亮晶方解石大小、底基质岩性和粘性在臼齿构造发育过程中具有重要作用; 相对的, 岩性均一地层中臼齿构造形态多种多样。而臼齿构造直径与其弯曲度之间的关系说明臼齿构造形成过程本身也影响最终的臼齿构造形态。在此基础上, 讨论了臼齿构造在分析古海洋环境方面的重要意义。

Morphological Characteristics and Genesis of Molar-Tooth Structures in Gaoyuzhuang Formation of Jixian Area
Abstract:Based on a detailed petrographic examination of MT structures from the Proterozoic Gaoyuzhuang Formation in Jixian, this paper made an interpretation of the microscale relationship between crack morphology and lithology as well as potential rheology and variability of the surrounding substrate by tracing the distribution of petrographically distinctive MT microspar. The results show that grain size, substrate lithology and substrate cohesion all played critical roles in the development of MT. In contrast, the presence of a wide range of MT morphologies within petrographically homogeneous substrates and the existence of an apparent relationship between crack diameter and sinuosity suggest that the void-forming process itself also played a role in determining the final morphology of MT. On such a basis, this paper discusses the significance of the molar structure in the analysis of the ancient marine environment.
