| 摘 要： | 为了对中亚造山成矿带东段南缘红旗岭岩浆型铜镍硫化物矿床深部（500～1 000 m）隐伏矿体进行成矿预测，采用高精度重力和2.5维人机交互式反演方法，对含矿性较好的镁铁质—超镁铁质岩体（如#1、#3及新#3岩体）进行底部含矿性研究。结果表明：高精度重力异常开展不同高度上延并结合垂向一阶导数等数据处理，可有效地厘定深部隐伏岩体空间展布；2.5维人机交互式反演方法可以识别深部微弱的矿致异常，推测研究区#3岩体埋深700～1 100 m存在5个脉状盲矿体。经钻探验证，成功发现32 259 t]镍矿（矿石平均品位达0.36%），其中②号矿体为最厚矿体，见矿深度为700～1 100 m，镍矿平均品位为0.39%，储量达27 433 t。

| Abstract: | Hongqiling
magmatic Cu-Ni sulfide deposit is located in the southeastern margin of the
Central Asian orogenic belt (CAOB). In this paper, the multi-degree vertical
derivative and 2.5-D interactive inversion technique are used to predict the
mineralization of the hidden orebodies in the deep (500-1 000 m) Cu-Ni deposit,
and to study the ore-bearing properties of the mafic-ultramafic rocks (such as
#1, #3 and new #3 plutons). The results show that the high-precision gravity
anomaly can effectively determine the spatial distribution of deep hidden
orebodies by carrying out data processing on the upper edge of different
heights and the vertical first-order derivative, and the 2.5-D interactive
inversion technique can be used to detect the weak anomaly caused by deep
orebodies. It is speculated that there are 5 blind vein-shaped orebodies in the
#3 pluton in the study area with a burial depth of 700-1 100 m. After drilling
verification, 32 259 t of Ni ore was successfully discovered (the average grade
of ore is 0.36%), of which No. 2 ore body is the thickest ore body, the ore
penetration depth is 700-1 100 m, the average Ni ore grade is 0.39%, and the
reserves are up to 27 433 t. |
