构造横剖面测制与恢复,是利用在地表观察测量或近地表获取的各种地质信息、数据资料来绘制地表和恢复地下较深部位的构造形态,建立剖面沿线的构造地质模型。然而,在实际工作中,能否获取足够的信息资料以及剖面恢复中合理有效的作图方法选择等,直接决定着所作构造横剖面的准确性、可靠性。该文就构造横剖面测制和恢复中存在的若干具体问题和拟采用的技术措施,进行了分析与讨论。
Tectonic cross-section measurement and restoration is the use of surface observations or near-surface acquired by the acquisition of a variety of geological information and data to map the surface and restore the deep underground tectonic shape, the establishment of section along the tectonic geological model. However, in practice, the availability of sufficient information and the selection of reasonable and effective mapping methods for profile restoration will directly determine the accuracy and reliability of the constructed cross-sections. This paper analyzes and discusses some specific problems existing in the construction and recovery of cross sections and the technical measures to be adopted.
