古地磁方法

Sr同位素方法和其它一些地层学方法，如古地磁方法和稳定同位素方法相比不需要那样高的采样密度，也不受地区、纬度和沉积相等因素的影响，因而应用较为简单。

Sr isotope method is independent of facies and latitude and may not require the high sample density of paleomagnetic and stable isotopic methods .

本文以云贵高原厚度分别为9.47m和5.4m的两个碳酸盐岩风化剖面为例，探讨了古地磁方法在碳酸盐岩风化剖面定年中的应用。

In this paper , two weathered profiles of 9.47m and 5.4m deep are made as example for the study on the application of paleomagnetism dating to terra rossa profiles .

从而使用古地磁方法确定的块体绕垂直轴的旋转量和地层绕水平轴的掀斜量更为接近客观实际。

In that case , it will enable us to get more reliable amounts of the rotation of the block around the vertical axis , and that of the tilting of the strata around the horizontal axis , based on paleomagnetic method .

目前为止，油田地应力方向的研究方法很多，每种测试技术都有其优点和局限性，本文主要讨论利用差应变分析和古地磁方法结合确定地应力方位的方法。

So far , many methods have been used for studying the in-situ direction of oilfields and every method has its advantages and disadvantages . This thesis focuses on the method that predicts in-situ stress orientation for wells using differential strain analysis ( DSA ) and palaeomagnetic orientation .
