摘要
本文叙述了吉林省辉南县半砬坡子铁矿的矿区地质特征,半砬坡子铁矿产于混合花岗岩或以黑云斜长片麻岩为主的残留地层之中,主要由Ⅰ-1、Ⅰ-2、Ⅱ、Ⅲ-1号4条工业矿体组成。圈定磁异常4个,其中Ⅰ-1号异常是本区最大的矿致异常,走向近东西,呈带状,长290 m,宽160 m,异常强度-1951~3103 nT。经探槽、钻探工程验证见矿良好。描述了矿体特征、矿石质量、矿石类型和特征、围岩特征,并对矿床成因及找矿标志进行了初步探讨。
In this paper,the geological features and magnetic anomalies of the Banlapozi iron ore mine in Huinan County,Jilin Province are described,the Banlapozi iron deposit is produced in the residual strata dominated by migmatitic granite or biotite plagioclase gneiss,which is mainly composed of four industrial ore bodiesⅠ-1,Ⅰ-2,ⅡandⅢ-1.Four magnetic anomalies are delineated,among which theⅠ-1 anomaly is the largest mine-induced anomaly in the area,trending near east and west,in a belt-like manner,with a length of 290 m,a width of 160 m,and an anomalous intensity of-1951 nT to 3103 nT.It has been verified by trench and drilling engineering that the ore is well intervened.The characteristics of the ore body,ore quality,ore type and characteristics,and surrounding rock characteristics were described,and the genesis and prospecting signs of the ore deposit were preliminarily discussed.
