地层学自产生以来的300余年,研究内容基本上属于史密斯地层学(Smith Stratigraphy)的范畴。史密斯地层学是指研究那些层序正常,横向上可以远距离追索对比,构造简单,无变质或变质轻微,海相火山岩系不发育,具较广地理分布的地层的学科。它的研究始于被称为“英国地质之父”的威廉.史密斯(W.Smith,1769—1839)。近数十年来,随着古大陆造山带研究的兴起,史密斯地层学在研究造山带地 Stratigraphy since its inception more than 300 years, the research content basically belongs to the field of Smith Stratigraphy (Smith Stratigraphy) category. Smith Stratigraphy is a discipline that studies stratigraphic strata that are normal in sequence, recoverable in the long distance in the horizontal direction, simple in structure, minor in metamorphism, slight in development, and undeveloped in the marine volcanic rocks. Its research began with William Smith (1769-1839), known as the “father of British geology.” In recent decades, with the rise of ancient continental orogenic belt research, Smith Stratigraphy in the study of orogenic belt
