构造倾斜会使原生剩磁偏角产生偏差，从而影响对地体构造旋转等特征的分析。对这种偏角偏差进行了理论分析和计算。倾伏褶皱在野外难以识别，即或识别，倾伏要素也很难准确测定。为此提出了利用多个参考点的古地磁资料分析地体运动特征的新方法。该方法是基于剩磁倾角数据，从而避免了偏角误差的影响，提高了分析的可靠性。利用该方法对我国西北地区的地质构造演化进行了研究，初步实现了该区古生代古地理的重建。
Tectonic tilt will lead to deviations of the primary residual magnetic declination, which will affect the analysis of features such as the rotation of the tectonics. The deviation of this deviation is analyzed theoretically and calculated. Piling folds in the field is difficult to identify, that is, or identify, subdued elements are also difficult to accurately determine. Therefore, a new method of analyzing the movement characteristics of the earth's surface using paleomagnetic data of multiple reference points is proposed. The method is based on remanence data to avoid the influence of declination error and improve the reliability of the analysis. By using this method, the geological tectonic evolution in the northwestern China is studied, and the Paleozoic paleogeography reconstruction in this area has been carried out.
