航空瞬变电磁法在塔源二支线铅锌铜矿床的应用研究
|
摘要
采用航空瞬变电磁法,在塔源二支线铅锌铜矿床开展森林沼泽景观区矿产资源勘查方法试验研究。结果显示,已知矿体航空瞬变电磁异常特征明显,d B/dt剖面曲线呈北低、南高的双峰异常,矿体集中分布在值为0. 2 ms～0. 28 ms团块状时间常数高值区北侧,对应视电阻率为190Ω·m～240Ω·m、向东倾斜的低阻体,经Fraser滤波后对应一北东向串珠状展布的线性高值带。研究表明:航空瞬变电磁法能有效地揭示森林沼泽景观区铅锌铜多金属矿体的空间展布特征,为同类型地区开展矿产资源勘查提供方法技术借鉴。
By using the method of airborne transient electromagnetic method in the two branch line of Tayuan Pb-Zn-Cu deposit,the exploration methods of mineral resources is carried out in the forest swamp landscape. The results show that the characteristics of the transient electromagnetic anomalies of the known ore bodies are obvious. The d B/dt profile is significant bimodal anomalies,and the ore bodies are concentrated in the edge of the high value area( 0. 2 ms ～ 0. 28ms) of the time constant. The correspond apparent resistivity value is 190 Ω·m ～ 240 Ω·m,tendency to east low resistance body. After Fraser filtering,a linear high value band corresponding to a north east beaded line is found. The results show that the method can effectively reveal the spatial distribution characteristics of lead zinc copper polymetallic ore deposits in the forest swamp landscape area,and can provide a reference for the exploration of mineral resources in the same area.
