溱潼凹陷E_f²底界的趋势面分析

THE TREND-SURFACE ANALYSIS OF THE BOTTOM OF E_f² IN QINTONG DEPRESSION

本文是趋势面分析在研究构造中的一次应用.文中简单地介绍了趋势面分析的原理;比较详细地阐述了所做工作的实际成果;初步分析了成果资料中某些局部构造在原有物探资料上未被发现的原因.最后指出,在地质变量存在某种不连续的情况下,利用趋势面分析以突出局部构造仍然是值得注意的.

This article deals with an application of the Trend-Surface Analysis method for the study of geologic structures. It gives briefly the principle of the method while elucidates at some length the practical results obtained. Preliminary analysis has been made for the reason why some of the local structures were not discovered from the original geophysical material. Finally, it has been pointed out that attention should be paid to the use of the method of trend-surface analysis when the geological conditions vary discontinuously in order to bring local structures into prominence.
