对昆阳群中采集的283块样品用热退磁法做了磁清洗处理,经精度检验,进行了统计分析.根据获得的古地磁结果,探讨了昆阳群地层所代表的古地磁极性和古纬度,建立了该地区中、晚元古界古地磁视极移路径,并与华北地块及扬子地块该时期的视极移路径进行了对比,讨论了其构造运动及相互之间的关系,认为下昆阳亚群与长城系古纬度相近,古地磁极性及视极移路径可比,时代相当.
A total of 283 samples collected from Kunyang Group were magnetically cleaned by thermal demagnetization method. The accuracy was tested and statistical analysis was carried out. Based on the paleomagnetic results obtained, the paleomagnetic polarity and paleosalinity represented by the Kunyang Group strata are discussed, and the polar-migrating path of the Middle Proterozoic Paleocene in the area is established. In this period, the polar shift paths are contrasted, and their tectonic movements and their relations are discussed. The lower Kunyang sub-group is similar to the paleo-latitude of the Great Wall, and the paleomagnetic polarity and the apparent shift path are comparable with those of the era.
