| REE Geochemistry of Marbles of the Zhenzhumen Formation of the Laoling Group in Southern Jilin Province |
| REE geochemical characteristics of the marbles of the Zhenzhumen Formation can be divided into two kinds. The first is distributed in AreaⅠand the second in Area II. The REE geochemistry in Area I is characterized by relatively low REE content, no fractionation and flat REE pattern, whereas that in Area II by comparatively high REE content, strong fractionation and right-oblique REE pattern. The difference in REE characteristics reflects different sources of REE and different geotectonic environments. Area I is an aulacogen related to deep faults, while Area II is a continental rift characterized by volcanic activity. The Zhenzhumen Formation has no stratigraphic significance, and hence should be disintegrated. |
