Metamorphic iron ore geological feature and prospectiong potential in Sidaogou area,Beijing city

The tectonic geophysical characteristics of Sidaogou iron mining area in Beijing have been systematically summarized through the geological mapping and high-precision magnetic measurement survey in a scale of 1∶10000 in this paper,which provide a reliable of geophysicist for the delineation of metamorphic iron ore.Three tectonic have been delineated based on the geological and geophysical analysis,and among them the C_sd-3 anomaly belt has a better prospecting potential,and put forward the next step working suggestion.
