本文分析研究了云南省内九个地磁台站在湾扰、磁暴急始中的特点,发现在这两种地磁短周期事件中△Z的位相及Wiese矢量指向,在省内东西两半部存在着显著差异。作者按DV型CA的观点并结合有关地震活动性、地质构造、水文等资料推测:沿着红河断裂带方向,在其邻侧的地壳、上地幔中存在着一个高导层。这个北西方向延伸的高导层,其南端在思茅的东侧,北端在丽江的西侧。高导层的规模较大,对省内地磁短周期变化具有控制作用。 文中提出,这一研究工作还是很初步的。考虑到这一高导层的研究对于地磁工作和红河断裂带的研究具有一定的意义,有必要把这一项工作继续深入下去。
This paper analyzes and studies the characteristics of nine geomagnetic stations in Yunnan Province during the Bay disturbance and magnetic storm emergency. It is found that the phase of △ Z and the Wiese vector pointing in these two geomagnetic short-period events exist in both east and west of the province Significant differences. According to the viewpoint of DV type CA and combined with the information on seismic activity, geological structure and hydrology, the author speculates that there is a high-conductivity layer in the crust and upper mantle along the Honghe fault zone. The northwest extension of the high-conductivity layer, the southern end of Simao in the east, north of Lijiang in the west. The high-conductivity layer is large in scale, and plays a controlling role in the short-period change of geomagnetic in the province. The article proposed that this research is still very preliminary. Considering that the study of this high conductivity layer has certain significance for the geomagnetic work and the study of the Red River fault zone, it is necessary to continue this work.
