中文摘要:
      为了说明地面高精度磁法在“新余式”铁矿找矿应用中的可行性和有效性,根据“新余式”铁矿具磁性的特点,利用加拿大产GSM-19T质子磁力仪,在吉水铁矿区进行了1:1万地面高精度磁法测量,获得了磁异常数据。通过对磁异常ΔT化极数据进行转换处理和向上延拓提取分析,圈定了C1、C2两处磁异常,通过槽探、钻探工程的验证,发现了铁矿体,在吉水铁矿区勘查中起到了直接、快速找矿和靶区圈定,取得了较好的找矿效果,为“新余式”铁矿勘查提供了地球物理依据和找矿指导作用。
英文摘要:
      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.
