一、前言 1979年6月地质矿产部航测总队出版了《中国航空磁力异常△T图》,该图范围包括我国东北、华北和部分华东地区(即经度102°以东、纬度32°以北地区)。并对我国东部陆地及大部分海域的航空磁力异常作了统一调平工作。我们收集了上述资料及部分中国海域及其毗邻海域(下称邻海)的磁测资料。做出了一张经过调平的中国东部及其邻海航空磁力异常△T图。并采用画航磁异常轴向这个最简单的方法,画出具有客观性和直观性的航磁异常轴向图,进行地质解释,提出研究结果,介绍了研究的方法,力争从这一航磁异常轴向图中提出更多的地质信息。在这以前,朱英发表了《华北地块的大地构造和鞍山式铁的矿分布规律——根据航空磁测结果的初步分析》。侯重初、刘寿彭等作了《泛华北地区航磁资料数据处理结果与初步地质解释》。姜枚作了磁特征线的研究等工作。
I. Introduction In June 1979, the Air Navigation Corps of the Ministry of Geology and Minerals published the “China Aviation Magnetic Abnormality △ T map”, which covers the northeast China, northern China and parts of eastern China (ie, east longitude 102 ° and northern latitude 32 ° ). And made uniform leveling work on the aviation magnetic anomalies on the land in the eastern part of China and in most of the sea areas. We have collected the above information and some of the magnetic measurements of some areas of China and its adjacent sea areas (hereinafter referred to as the “adjacent sea”). Made a leveling of the eastern China and its adjacent sea magnetic anomaly △ T map. And by using the simplest way to draw anomalous axial of magnetic anomaly, we can draw an axial aeromagnetic anomaly with objectivity and intuition, make a geological interpretation, put forward the research results, introduce the research methods, Abnormal axial map proposed more geological information. Prior to this, Zhu Ying published “The Geotectonic Structure of the North China Block and the Distribution of Anshan-type Iron Ore - A Preliminary Analysis Based on Aeromagnetic Survey Results”. Hou Chongchu, Liu Shoupeng made a “pan-North China aeromagnetic data processing results and preliminary geological interpretation.” Ginger made magnetic characteristics of the research work.
