地震层析成像在工程勘测中的应用

目前,地震层析成像在许多工程勘测和矿产勘探部门开始试用,迫切需要有这方面的指南性的文章。本文综合介绍地震层析成象的原理、数据采集技术、图象重建的理论和方法,并通过一个成功的应用实例说明方法的应用效果。作为一种新的物探方法,地震层析成象的应用仍然存在许多问题,如非线性图像重建,文章对存在问题及对策作了详细讨论。

CHARACTERISTICS OF PRIMARY GEOCHEMICAL ZONING IN COPPER-IRON-GOLD POLYMETALLIC DEPOSITS OF SOUTHEASTERN HUBEI AREA AND ORE-PROSPECTING SIGNIFICANCE OF THE ZONALITY PATTERN

The seismic tomographic imagery has begun to be used on a trial basis in lots ofdepartments undertaking engineering survey and ore resource exploration. As a result, papers gui-ding the work in this aspect is urgently needed. This paper introduces comprehensively principlesof seismic tomographic imagery, data collection techniques and theories and methods for imagereconstruction. With an example of its successful application, the paper illustrates the effective-ness of this method. As a new geophysical prospecting method, the seismic torao?raphic imagerystill has many problems to be solved in its application, such as the reconstruction of the nonli-near image. A detailed discussion is made concerning these existing problems and the steps tosolve them.
