Discovery of spherulitic magnetic grains and its iron oxide mineralogy in paleosols


, : Discovery of spherulitic magnetic grains and its iron oxide mineralogy in paleosols. Acta Agriculturae Zhejiangensis 12(1): 31-33

The morphology and mineralogy of spherulitic magnetic grains separated by high-gradient magnetic separation in palaeosols was investigated by scanning and transmission electron microscopy (TEM), magnetic measurements and X-ray diffraction. The spherulitic magnetic grains were 250-1000 micro m in diameter, indicating that they were a complex of suparaparamagnetic and stable-single domain ferrimagnetic minerals.
