Abstract:
      In order to illustrate the feasibility and validity of the ground high-precision magnetic method in the prospecting of "Xinyu" iron ore deposit, according to the magnetic characteristics of "Xinyu" iron ore deposit, the ground high-precision magnetic method was used to measure the magnetic anomaly data in Jishui iron ore district by using GSM-19T proton magnetometer made in Canada. Two magnetic anomalies, C1 and C2, are delineated by transforming and processing the data of_T polarization of magnetic anomaly and extracting and analyzing the upward continuation. The iron ore bodies are found through the verification of trench exploration and drilling engineering. The direct and rapid prospecting and target delineation are carried out in the exploration of Jishui Iron Ore Mine Area, and good prospecting results are obtained. "Iron ore exploration provides geophysical basis and guiding role in prospecting.
