摘要
基于重力勘探测量精度高、时间周期短等优点,利用重力勘探对测区2条测线进行测量,利用经过各种校正后的重力布格异常数据编绘出舜耕山断裂的重力异常等值线图,结合磁法勘探的资料和区域地质背景,分析重力异常产生的原因,野外数据表明,重力异常分布较为复杂,总体上在-10~40 g.u.之间变化,高、低重力异常分布区域明显,在重力异常突变处圈定了舜耕山断裂的存在,舜耕山断裂发育位置在7号测点附近,舜耕山断裂向东西向延伸,推测舜耕山断层走向为近东西向。
Based on the advantages of high accuracy and short time period in gravity survey,two survey lines in the survey area are measured by gravity survey,the isogram of gravity anomaly of Shungenshan fault is drawn by using the gravity Boog anomaly data after various kinds of correction,and the cause of gravity anomaly is analyzed combining the data of magnetic prospecting and the regional geological background,the distribution of gravity anomaly is more complex,and the whole is-10 g.u.to 40 g.u..The distribution of high and low gravity anomalies is obvious,the existence of Shungenshan fault is delineated at the sudden change of gravity anomaly,the development location of Shungenshan fault is near survey point 7,and Shungenshan fault extends eastward and Westward,the strike of Shungengshan fault is supposed to be nearly EW.
