Abstract:This paper discusses the posibility of palaeomagnetic research on Precambrian metamorphic rocks from the relationship between metamorphism and acquired magnetic remanence of minerals and rocks, correlation between the time for acquisition of magnetic remanence and isotopic geochronological records and influence upon directions of magnetization by rock deformation during metamorphism or oro-genic processes. Some examples of paleomagp.etic studies of early Precambrian rocks abroad are cited. Meanwhile, take for example the palaeomagnetic results from Precambrian metamorphic rocks in northern Fujian Province, this paper discusses the reliability of and their significance in geology and tectonics.
