在参与“全国重要矿产和区域成矿规律研究”项目中,通过对现有地质地球物理工作成果的再归纳、分析,发现往年的资料仍有深入研究的潜力。一些曾被认为是正常场的低缓磁异常,经过现代技术的探测,被勘探出新的矿田;一些隐伏矿体,也揭去了面纱,展现给我们优质的深部矿产资源。本文仅以岩浆岩型铁矿为主,归纳了该类型矿床的地球物理特征,以期为找矿工作提供有益信息。
In participating in the “Research on the Laws of Mineral Resources and Regional Mineralization in China”, through the reevaluation and analysis of the existing achievements of geophysical and physical work, it is found that the data of previous years still have the potential for further research. Some of the slow magnetic anomalies, once considered normal fields, have been explored to new fields through the exploration of modern technologies. Some of the hidden ore bodies have also revealed their veils and show us good quality deep mineral resources. In this paper, only the magmatic rock type iron ore mainly summarizes the geophysical characteristics of this type of deposit, in order to provide useful information for prospecting work.
