前言国外运用古地磁学除在研究地质年代学、地层学和大地构造方面已取得很大的成就外,在预测矿产,研究矿床成因及磁测资料的地质解释方面,也获得某些可喜的成果.古地磁学将有可能成为地质找矿中的一种工具.我国把古地磁用于地质矿产勘探方面所做工作还不多,这里介绍的鞍山弓长岭铁矿区所做的古地磁工作,虽获得了一点效果,但还只是一个初步的尝试. Preface The use of paleomagnetic geography abroad has made great achievements in geochronology, stratigraphy and geotectonics. Some promising achievements have also been made in predicting the mineralization, studying the genesis of the deposit and geologic interpretation of magnetic data Paleomagnetism will likely become a tool in geological prospecting.Our country does not do much work on paleomagnetic exploration for geology and mineral resources. The paleomagnetic work done by the Anshan Gongchangling iron ore area , Although a little effect, but only a preliminary attempt.
