摘要
元素的地球化学异常反映了元素的富集与迁移及其成矿作用特征,也可在一定程度上反映矿体的分布规律。通过对甲玛矿区外围的岩石和土壤的地球化学测量,将异常分为六类(A1,A2,B1,B2,B3,C2),并圈定A,B,C类成矿远景区各一处。初步推测甲玛外围为斑岩型、矽卡岩型Cu,Mo矿产潜力区。
The elemental geochemical anomaly reflects the migration or accumulation of elements and the the mineralization features,which reflect the ore body distribution to some extent.According to characteristics of chemical measurement of the rock and soil of Jiama deposits' periphery area,the anomaly can be divided into 6 types:A_1,A_2,B_1,B_2,B_3,C_2,which are delineated into three mineralization prospect areas(zone A,B and C).Based on the preliminary results,the periphery area of Jiama deposits are copper and Molybdenum potential area.
