| 摘 要： | 通过1/1万的高精度磁法测量,在哈西亚图地区圈出了C1、C2、C3三个异常,从目前成果看,矿致异常的异常特征很明显:异常为南正北负,正磁异常大于负磁异常,峰值较高,当△T在3000 nT-8000nT区间时,梯度陡的磁异常区域,磁铁矿体埋藏深度较浅,一般小于20m,当△T大于8000 nT时,地表可揭露出磁铁矿(化)体。此次普查工作大致查明C2-1、C3磁异常为矿致异常,含矿岩性为矽卡岩,矿床属似层状矽卡岩型铁多金属矿床[4]。

| Abstract: | Applying 1/10000 high-precision magnetic measurements to circle C1,C2,C3 three anomaly areas in Ha Seattle.Viewing from the current results,anomaly characteristics of ore-caused anomaly is obvious,south of the anomaly is negative,and north is positive.The positive magnetic anomaly is greater than the negative,the peak is higher,when △T is between 3000 nT and 8000nT,in the steep gradient of the magnetic anomaly zone,buried depth of magnetite body is shallower,generally less than 20m;when △T is greater than 8000 nT,the surface outcrop magnetite(mineralized) orebody.This survey generally identifies the C2-1 and C3 are ore-caused anomalies,ore-bearing rock is skarn,type of the deposits are bedded skarn metal deposits of more iron. |
