煤的积累和石油页岩的形成发生在每种能源中的独特的盆地条件下发生。在特别的特殊条件下，它们可以在同一盆地共存。许多研究已经进行了解释煤积累以及油页岩的金属遗传模型的理论和模型。本文试图解决煤炭和石油页岩共存的关键理论问题。我们研究不同类型的盆地，以研究这种共存的地理基础。我们得出的结论是，盆地的构造活动控制了盆地填充的整体特征，因此代表了煤炭和油页岩共存的外部条件。盆地的情节构造活性和构造演化导致水系统和材料供应的变化，从而导致各种环状煤炭和油页岩形成。过去的气候条件决定了是否有合适的材料形成煤炭和石油页岩。我们确定了共存的六种主要类型的煤炭和油页岩。我们的研究表明，所有六种类型都可以发生在水扩展的系统中。周期性的湖泊洪水有利于多层煤炭和石油页岩的发展。本文表明，适合形成煤和油页岩的条件之间存在一些相似之处和差异。我们通过对盆地背景，盆地空间框架，地层框架，动态沉积框架及其在共存空间中的发展以及形成的控制机制的全面分析，建立了煤和油页岩共存的模型，以及共存的过程，共存过程，分布和分布和出现。
The accumulation of coal and the formation of oil shale occur in basin conditions that are unique for each of these energy resources. In particularly special conditions, they can coexist in the same basin. Many studies have been carried out on theories and models explaining coal accumulation, as well as on the metallogenic model of oil shale. This paper attempts to address the key theoretical issue of the coexistence of coal and oil shale. We study different types of basins in order to investigate the geotectonic basis of such coexistence. We conclude that the basins’ tectonic activity controls the overall characteristics of basin filling, and thus represents the external conditions for the coexistence of coal and oil shale. Episodic tectonic activity and the tectonic evolution of the basins leads to changes of the water system and material supply, resulting in various cyclic patterns of coal and oil shale formations. Past climatic conditions determine whether there were suitable materials to form coal and oil shale. We identified six main types of coexisting coal and oil shale. Our research shows that all six types can occur in the system tract of water expansion. Periodic lake flooding is conducive for the development of coal and oil shale in multiple thin layers. This paper demonstrates that there are some similarities and differences between the conditions suitable for the formation of coal and oil shale. We establish a model for the coexistence of coal and oil shale through a comprehensive analysis of basin background, basin spatial framework, stratigraphic framework, dynamic field of deposition and its evolution in the coexisting space, and the controlling mechanism of the formation, together with the coexistence process, distribution and occurrence.
