With a low mechanical strength and high Poisson's ratio, coal can exhibit brittle or ductile deformation when exposed to lower levels of stress, strain rate, pressure, and temperature compared to the adjacent sedimentary rocks (sandstone, mudrock, and carbonate). The physical and optical properties of deformed coals have been extensively examined. However, it is still unclear if within the shallow crust, tectonic stresses can enhance the coalification and how the coal organic structure responds to ductile deformation. Here, dynamic-related coalification was reviewed to identify the significance of ductile deformation within the shallow crust. Compared with the brittle and transition stages, the dynamic-related coalification initiated within the ductile deformation could also exert a more substantial impact, resulting in a distinct evolution such as enhanced structural alignment, increased curvature in aromatic molecules, higher aromaticity, and generation of secondary defects. Although these alterations are similar to those resulting from normal thermometamorphism, their patterns are influenced by the stress mode and tectonic exposure, which was related to the host basins. Either tension or extrusion stresses under a high strain rate (corresponding to normal or high-angle reverse faults) are favorable for brittle deformation, where the dynamic-related coalification was presented as a stress degradation process. However, ductile deformation (or even rheology) was produced from compressive-stress, compressive-shear stress, or pure shear stress accompanying low strain rates (corresponding to the nappe, layer slip, and strike-slip faults). There, the deformation-related coalification was promoted to a greater extent and was present as stress condensation. Thus, the deformation extent of coal and the accompanying deformation-related coalification is of significance for identifying the ductile deformation within the shallow crust. The outcome of this paper can be applied to the geological analysis of coalfield structure in tectonically complex regions.

与邻近的沉积岩（砂岩、泥岩和碳酸盐岩）相比，煤的机械强度低且泊松比高，当暴露于较低水平的应力、应变率、压力和温度时，煤会表现出脆性或韧性变形。变形煤的物理和光学性质已被广泛研究。然而，尚不清楚在浅地壳内，构造应力是否可以增强煤化以及煤有机结构如何响应延性变形。在这里，回顾了与动力相关的煤化，以确定浅地壳内延性变形的重要性。与脆性和过渡阶段相比，在韧性变形中引发的与动力相关的煤化也会产生更实质性的影响，导致明显的演变，例如增强的结构排列、增加的芳香分子曲率、更高的芳香性和二次缺陷的产生。尽管这些变化与正常热变质作用产生的变化相似，但它们的模式受到与宿主盆地有关的应力模式和构造暴露的影响。高应变率（对应于正常或大角度反向断层）下的拉伸或挤压应力都有利于脆性变形，其中与动力相关的煤化表现为应力退化过程。然而，塑性变形（甚至流变）是由伴随低应变率（对应于推覆、层滑和走滑断层）的压应力、压剪应力或纯剪应力产生的。那里，与变形相关的煤化作用得到更大程度的促进，并以应力凝聚的形式存在。因此，煤的变形程度及其伴随的变形煤化对于识别浅层地壳内的韧性变形具有重要意义。本文研究成果可应用于构造复杂地区煤田构造地质分析。
