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。
        In order to illustrate the feasibility and effectiveness of the ground high-precision magnetic method in the"Xinyu type"iron ore prospecting application,according to the magnetic characteristics of the"Xinyu type"iron ore,the Canadian GSM-19 Tproton magnetometer was used in Jishui iron mine.a 1:10000 ground high-precision magnetic method measurement was carried out in the mining area,and magnetic anomaly data was obtained.Through the transformation processing of the magnetic anomalyΔTpolar data and the upward extension extraction analysis,the magnetic anomalies of C1 and C2 were delineated.Through the verification of trenching and drilling engineering,the iron ore body was discovered and explored in the Jishui iron ore district.It has played a direct and rapid prospecting and target area delineation,and achieved good prospecting effect,providing geophysical basis and prospecting guidance for the"Xinyu type"iron ore exploration.
