摘要:
Additional palaeomagnetic results for the Särna alkaline body of western Sweden confirm the study of Bylund & Patchett (Bylund, G. & Patchett, P. G., 1977: Palaeomagnetism and Rb-Sr isotopic evidence for the age of the Särna alkaline complex, western central Sweden.Lithos 10, 73–79). A combined mean direction (D=201°,I=−23°) from both studies yields a palaeomagnetic pole at 13.6° W, 38.1° S (dp3.9°,dm7.3°) correlating with other European Upper Carboniferous data. Thermomagnetic determinations and petrologic study suggests that pyrrhotite is the predominant mineral responsible for magnetic remanence.
