| 英文摘要 | Changyi iron deposit, located at Jiaobei terrane, eastern North China Craton (NCC), is a banded iron formation (BIF) deposit kept in Paleoproterozoic Fenzishan Group. Ore bodies of the deposit are lens- or layer-like and mainly composed of amphibolite-bearing magnetite quartzite, which have expericed >636 degrees C amphibolite facies metamorphism. Major contents of SiO2 and Fe2O3T(SiO2 + Fe2O3T = 82.5% similar to 97.7%) coupled with minor Al2O3, MgO and CaO suggest that the ores originated from chemical deposition contaminated by clasitic or pelitic materials. LREE depletion, high Y/Ho ratios and positive La and Y anomalies indicate a marine environment. In addition, high Ti/V ratios, high Cr, Co and Ni concentrations as well as positive Eu anomalies suggest involvement of high-temperature hydrothermal fluids, implying ore-fanning elements were related to submarine volcanic activities. The lack of negative Ce anomalies also suggests an anoxic environment. Compared with Archean BIFs of NCC, the higher Al2O3, MgO, CaO and K2O contents as well as weaker positive Eu anomalies indicate that the Paleoproterozoic Changyi HIE deposit obtained more elastic or pelitic materials and less hydrothermal fluids in a shallower marine environment. |
