中文摘要:
      本文分析了地球物理找矿方法在甘肃肃北红柳疙瘩铁矿勘查中的找矿效果,研究结果表明矿床的含矿岩石主要为纤闪石化辉长岩,矿体多以板状、不规则状透镜状产出,总体走向呈北北东向,倾向北西,倾角中等;1∶1万地面高精度磁法测量、1∶1万激电中梯扫面和激电测深方法在该矿床具有较好的应用效果,圈定出2处(M1、M2)局部磁异常区和3处(JD1、JD2、JD3)激电异常,根据M2磁异常和JD3激电异常圈定的综合异常具有较大的找矿潜力,经钻探工程验证,发现了一定规模的钛铁矿体。
英文摘要:
      This paper analyzes the prospecting effect of geophysical prospecting method in the exploration of Hongliugeda iron deposit in Gansu Province, and the results show that:The ore-bearing rocks of the deposit are mainly fiber-flash petrochemical gabbro, ore bodies are mostly plate-shaped, irregular lenticular output, the overall trend is northward eastward, inclined to north West, inclination medium; 1∶10000 ground high-precision magnetic method measurement, 1∶10000 excitation in the ladder sweep surface and excitation sounding method in the deposit has a good application effect, identified 2 places (M1, M2) excitation anomalies of local magnetic anomaly area and 3 places (JD1,JD2 and JD3) have great prospecting potential according to the comprehensive anomaly of M2 magnetic anomaly and JD3 excitation anomaly, and a certain scale titanium ore body is found by drilling engineering verification.
