一、前言地层接触关系的研究是追溯地壳运动历史(运动方式、强弱、范围、延续时间等)和揭示矿产的生成、富集、赋存与破坏条件的重要方法;是地层学、地史学、构造地质学、古地理学等专门学问的重要组成部分。所以研究地层接触关系有非常重要的理论意义和实际意义。但是在目前的实际工作中对此问题却存在着一定的混乱现象,例如同一现象有人认为是整合,有人则认 I. Preface The study of stratigraphic contact is an important way to trace the history of the crustal movement (mode of movement, strength, scope, duration, etc.) and reveal the conditions for the formation, enrichment, occurrence and destruction of the mineral; , Structural geology, paleogeography and other specialized knowledge of the important components. Therefore, the study of the relationship between strata has very important theoretical and practical significance. However, there is a certain confusion in the current practical work on this issue. For example, some people think that the same phenomenon is amalgamated, while others think that
