Cyclostratigraphy was born in 1980s as a subdiscipline of stratigraphy. Based on the Milankovitch theory, outcrop sections and cores are analyzed with methods such as geochemistry, spectrum analysis, and time-sequence analysis to study the complex responses of orbital forcing to sedimentary records.

旋回地层学作为一门独立的地层分支学科诞生于20世纪80年代，它以米兰科维奇天文轨道旋回为理论基础，以露头剖面、岩心等为研究对象，应用地球化学、光谱分析和时间序列分析等方法，研究天文轨道参数周期性变化在地层记录中的沉积响应。

Research on Coal-forming Environment and Sequence Stratigraphy in Coal Measures Strata;2.

结果表明：在高煤级煤早期阶段，形成于不同成煤环境的太原组煤与山西组煤的煤化特征仍有差异，在第三次煤化作用跃变之后这种差异逐渐缩小消失；高煤级煤分别以第三次和第四次煤化作用跃变为界，呈现出阶段性演化的特征，每阶段的演化机理有所不同；第三次煤化作用跃变中大分子结构的演化以芳构化作用主为，第四次煤化作用跃变则以强烈的环缩合作用占优势。
